Safety Information
For your own safety and the safety of others, and to prevent damage to the device and
vehicles upon which it is used, it is important that the safety instructions presented
throughout this manual be read and understood by all persons operating or coming into
contact with the device.

There are various procedures, techniques, tools, and parts for servicing vehicles, as well
as in the skill of the person doing the work. Because of the vast number of test
applications and variations in the products that can be tested with this equipment, we
cannot possibly anticipate or provide advice or safety messages to cover every
circumstance. It is the automotive technician’s responsibility to be knowledgeable of the
system being tested. It is crucial to use proper service methods and test procedures. It
is essential to perform tests in an appropriate and acceptable manner that does not
endanger your safety, the safety of others in the work area, the device being used, or the
vehicle being tested.

Before using the device, always refer to and follow the safety messages and applicable
test procedures provided by the manufacturer of the vehicle or equipment being tested.
Use the device only as described in this manual. Read, understand, and follow all safety
messages and instructions in this manual.

Safety Messages
Safety messages are provided to help prevent personal injury and equipment damage.

ii
DANGER
When an engine is operating, keep the service area WELL VENTILATED or attach a
building exhaust removal system to the engine exhaust system. Engines produce carbon
monoxide, an odorless, poisonous gas that causes slower reaction time and can lead to
serious personal injury or loss of life.

SAFETY WARNINGS

 Always perform automotive testing in a safe environment.

 Wear safety eye protection that meets ANSI standards.
 Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or hot
engine parts.
 Operate the vehicle in a well-ventilated work area, for exhaust gases are poisonous.
 Put the transmission in PARK (for automatic transmission) or NEUTRAL (for manual
transmission) and make sure the parking brake is engaged.
 Put blocks in front of the drive wheels and never leave the vehicle unattended while
testing.
 Be extra cautious when working around the ignition coil, distributor cap, ignition wires
and spark plugs. These components create hazardous voltages when the engine is
running.
 Keep a fire extinguisher suitable for gasoline, chemical, and electrical fires nearby.
 Do not connect or disconnect any test equipment while the ignition is on or the
engine is running.
 Keep the test equipment dry, clean, free from oil, water or grease. Use a mild
detergent on a clean cloth to clean the outside of the equipment as necessary.
 Do not drive the vehicle and operate the test equipment at the same time. Any
distraction may cause an accident.
 Refer to the service manual for the vehicle being serviced and adhere to all
diagnostic procedures and precautions. Failure to do so may result in personal injury
or damage to the test equipment.
 To avoid damaging the test equipment or generating false data, make sure the
vehicle battery is fully charged and the connection to the vehicle DLC is clean and
secure.
 Do not place the test equipment on the distributor of the vehicle. Strong electro-
magnetic interference can damage the equipment.

4.5 Generic OBDII Operations
OBDII/EOBD vehicle diagnosis option offers a quick way to check for DTCs, isolate the
cause of an illuminated malfunction indicator lamp (MIL), check monitor status prior to
emissions certification testing, verify repairs, and perform other emissions-related
services. The OBDII direct access option is also used for testing OBDII/EOBD-compliant
vehicles that are not included in the Diagnostics database. Diagnostics toolbar buttons
at the top of the screen are available for specific vehicle diagnostics. See Table 4-2
Diagnostics Toolbar Buttons for details.

4.5.1 General Procedure

 To access the OBDII/EOBD diagnostics functions
1. Tap the Diagnostics application button from the MaxiCheck Job Menu. The
Vehicle Menu will appear.
2. Tap the EOBD button. There are two options for establishing communication
with the vehicle.
 Auto Scan — select to establish communication using each protocol in
order to determine which one the vehicle is using.
 Protocol — select to open a submenu of available protocols. A
communications protocol is a standardized way of data communication
between an ECM and a diagnostic tool. Global OBD may use several
different communications protocols.
3. Select a specific protocol under the Protocol option. Wait for the OBDII
Diagnostics Menu to appear.
4. Select a function to continue. Supported functions may vary by vehicle.
 DTC & FFD
 I/M Readiness
 Live Data

 Figure 4-23 OBDII Diagnostics Menu Screen

4.5.2 Function Descriptions

This section describes the various functions of each diagnostic option:

DTC & FFD

When this function is selected, the screen displays a list of stored codes and pending
codes. When the Freeze frame data of certain DTCs are available for viewing, a
snowflake button will display on the right side of the DTC item. The Erase Codes and
Read codes functions can be applied by tapping the function buttons at the bottom of the
screen.

Figure 4-24 DTC & FFD Menu Screen

37
 Stored Codes
Stored codes are emissions-related DTCs from the ECU of the vehicle. OBDII/EOBD
codes are prioritized according to their emissions severity, with higher-priority codes
overwriting lower-priority ones. The priority of the code determines the illumination
of the Malfunction Indicator Light (MIL) and the codes erase procedure.
Manufacturers rank codes differently, so DTCs may vary by vehicle.

 Pending Codes
These are codes whose storing conditions have been met during the last drive cycle,
but need to be met on two or more consecutive drive cycles before the DTC is stored.
The purpose of displaying pending codes is to assist the service technician after a
vehicle repair when diagnostic information is cleared, by reporting test results after
a single drive cycle.
a) If a test fails during the drive cycle, the DTC associated will be reported. If the
pending fault does not occur again within 40 to 80 warm-up cycles, the fault is
automatically cleared from memory.
b) Test results reported do not necessarily indicate a faulty component or system.
If test results indicate another failure after additional driving, a DTC is stored to
indicate a faulty component or system.
 Freeze Frame
In most cases, the stored frame is the last DTC reported. Certain DTCs, those that
have a greater impact on vehicle emission, have a higher priority. In these cases,
DTCs of the highest priority will be retained. Freeze frame data includes a "snapshot"
of critical parameter values at the time the DTC is stored.
 Erase Codes
This option is used to clear all emissions-related diagnostics data including DTCs,
freeze frame data, and specific manufacturer-enhanced data from the vehicle ECU.
This option resets the I/M Readiness Monitor Status for all vehicle monitors to “Not
Ready” or “Not Complete”.
A confirmation screen will appear when the Clear Codes option is selected to prevent
accidental loss of data. Select Yes on the confirmation screen to continue or No to
exit.

I/M Readiness

This function is used to check the readiness of the monitoring system. It is an excellent
function to use prior to having a vehicle inspected for local emissions compliance.
Selecting I/M Readiness opens a submenu with two choices:

 Since DTCs Cleared — displays the status of monitors since the last time the DTCs
were erased.
 This Drive Cycle — displays the status of monitors since the beginning of the current
drive cycle.

38
Live Data

This function displays the real time PID data from the ECU. Displayed data includes
analog and digital input and output, and system status information broadcast in the
vehicle data stream.
Live data can be displayed in various modes. See Live Data for detailed information.

On-Board Monitor

This option allows you to view the results of On-Board Monitor tests. The tests are useful
after the service when a vehicle's control module memory is already erased.

Component Test

This function enables dual-directional control of the ECM so that the tablet can transmit
control commands to operate the vehicle systems. This function is useful in determining
how well the ECU responds to a command.

Vehicle Information

This function enables the display of the vehicle identification number (VIN), calibration
identification number, calibration verification number (CVN), and other information of the
test vehicle.

Vehicle Status

This function checks the current condition of the vehicle, such as the communications
protocols of OBDII modules, quantity of fault codes, and the status of the Malfunction
Indicator Light (MIL).

 Service
The Service application is specially designed to provide quick access to the vehicle
systems for various scheduled service and maintenance tasks. The typical service
operation screen is a series of menu-driven commands. Follow the on-screen
instructions to select appropriate options, enter values or data, and perform necessary
actions. The application will display detailed instructions to complete selected service
operations.

After entering a special function, the screen will display two options: Diagnosis and Hot
Functions. Diagnosis enables the reading and clearing of codes, which is sometimes
necessary after completing certain special functions. Hot Functions consists of sub
functions of the selected special function.

The most commonly used services are described in this chapter.

5.1 Oil Reset Service

Perform reset for the Engine Oil Life system, which calculates an optimal oil life change
interval depending on the vehicle driving conditions and climate. The Oil Life Reminder
must be reset each time the oil is changed so that the system can calculate when the
next oil change is required.

IMPORTANT
 Always reset the engine oil life to 100% after every oil change.
 All required work must be carried out before the service indicators are reset. Failure
to do so may result in incorrect service values and cause DTCs to be stored by the
relevant control module.
 For some vehicles, the tool can reset additional service lights such as maintenance
cycle and service interval. On BMW vehicles for example, service resets include
engine oil, spark plugs, front/rear brakes, coolant, particle filter, brake fluid, micro
filter, vehicle inspection, exhaust emissions inspection and vehicle checks.

5.2 Electronic Parking Brake (EPB) Service

This function has a multitude of usages to maintain the electronic braking system
including deactivating and activating the brake control system, assisting with brake fluid
control, opening and closing brake pads, and calibrating brakes after disc or pad
replacement.

45
 EPB Safety

It can be dangerous to perform Electronic Parking Brake (EPB) system maintenance, so

before you begin the service work, please keep the following rules in mind:

 Ensure that you are fully familiar with the braking system and its operation before
commencing any work.
 The EPB control system may require deactivation before carrying out any
maintenance/diagnostic work on the brake system. This can be done from the tool
menu.
 Only carry out maintenance work when the vehicle is stationary and on level ground.
 Ensure that the EPB control system is reactivated after the maintenance work has
been completed.
NOTE
Autel accepts no responsibility for any accident or injury arising from the maintenance of
the EPB system.

5.3 Battery Management System (BMS) Service

The BMS (Battery Management System) allows the tool to evaluate the battery charge
state, monitor the closed-circuit current, register the battery replacement, and activate
the rest state of the vehicle.
NOTE
 This function is not supported by all vehicles.
 The sub functions and actual test screens of the BMS may vary by vehicle. Follow
the on-screen instructions to make correct selections.
The vehicle may use either a sealed lead-acid battery or an AGM (Absorbed Glass Mat)
battery. Lead acid batteries contain liquid sulphuric acid and can spill when overturned.
AGM batteries (valve regulated lead acid, VRLA batteries) also contain sulphuric acid,
but the acid is contained in glass mats between terminal plates.
It is recommended that the replacement aftermarket battery has the same specifications,
such as capacity and type, as the original battery. If the original battery is replaced with
a different type of battery (e.g., a lead-acid battery is replaced with an AGM battery) or a
battery with a different capacity (mAh), the vehicle may require reprogramming the new
battery type in addition to performing the battery reset. Consult the vehicle manual for
additional vehicle-specific information.

46
5.4 Steering Angle Sensor (SAS) Service
Steering Angle Sensor Calibration permanently stores the current steering wheel position
as the straight-ahead position in the steering angle sensor EEPROM. Therefore, the front
wheels and the steering wheel must be set exactly to the straight-ahead position before
calibration. In addition, the vehicle identification number is also read from the instrument
cluster and stored permanently in the steering angle sensor EEPROM. On successful
completion of calibration, the steering angle sensor fault memory is automatically cleared.
Calibration must always be carried out after the following operations:
 Steering wheel replacement
 Steering angle sensor replacement
 Any maintenance that involves opening the connector hub from the steering angle
sensor to the column
 Any maintenance or repair work on the steering linkage, steering gear or other
related mechanism
 Wheel alignment or wheel track adjustment
 Accident repairs where damage to the steering angle sensor or assembly, or any
part of the steering system may have occurred

NOTE
 AUTEL accepts no responsibility for any accident or injury arising from servicing the
SAS system. When interpreting DTCs retrieved from the vehicle, always follow the
manufacturer’s recommendation for repair.
 All software screens shown in this manual are examples, actual test screens may
vary for each vehicle being tested. Observe the menu titles and on-screen
instructions to make correct option selections.
 Before starting the procedure, make sure the vehicle has ESC. Look for the button
on dash.

5.5 Diesel Particle Filter (DPF) Service

The Diesel Particle Filter (DPF) function manages DPF regeneration, DPF component
replacement teach-in, and DPF teach-in after replacing the engine control unit.
The ECM monitors driving style and selects a suitable time to employ regeneration. Cars
driven a lot at idling speed and low load will attempt to regenerate earlier than cars driven
with higher load and speed. In order for regeneration to take place, a prolonged high
exhaust temperature must be obtained.
In the event of the car being driven in such a way that regeneration is not possible, i.e.,
frequent short journeys, a diagnostic trouble code will eventually be registered in addition
to the DPF light and "Check Engine" indicators. A service regeneration can be requested
in the workshop using the diagnostic tool.

47
 Before performing a forced DPF regeneration using the tool, check the following items:
 The fuel light is not on.
 No DPF-relevant faults stored in system.
 The vehicle has the specified engine oil.
 The oil for diesel is not contaminated.

IMPORTANT
Before diagnosing a problem vehicle and attempting to perform an emergency
regeneration, it is important to obtain a full diagnostic log and read out relevant measured
value blocks.

NOTE
 The DPF will not regenerate when the engine management light is on or when there
is a faulty EGR valve.
 The ECU must be re-adapted when replacing the DPF and when topping up the fuel
additive Eolys.
 If the vehicle needs to be driven in order to perform a DPF service, a second person
is required for the function: One person should drive the vehicle while the other
person observes the screen on the tool. Do not attempt to drive and observe the
tablet at the same time. This is dangerous and puts your life and the lives of other
motorist and pedestrians at risk.

5.6 Tire Pressure Monitor System (TPMS) Service

This function allows you to quickly look up the tire sensor IDs from the vehicle's ECU and
to perform TPMS replacement and reset procedures after tire sensors are replaced.

5.7 Immobilizer (IMMO) Service

An immobilizer is an anti-theft mechanism that prevents an automobile's engine from
starting unless the correct ignition key or other device is present. This device prevents
thieves from starting the car by a method known as hot wiring. Most new vehicles have
an immobilizer as standard equipment. An important advantage of this system is that it
doesn't require the car owner to activate it; it operates automatically. An immobilizer is
considered as providing much more effective anti-theft protection than an audible alarm
alone; many auto insurance companies offer lower rates for vehicles that are equipped
with an immobilizer.

As an anti-theft device, an immobilizer disables one of the systems needed to start a

car's engine, usually the fuel supply or the ignition. This is accomplished by radio
frequency identification between a transponder in the ignition key and a device called a
radio frequency reader in the steering column. When the key is placed in the ignition, the

48
transponder sends a signal with a unique identification code to the reader, which relays
it to a receiver in the vehicle's computer control module. If the code is correct, the
computer allows the fuel supply and ignition systems to operate and start the car. If the
code is incorrect or absent, the computer disables the system, and the car will be unable
to start until the correct key is placed in the ignition.

The IMMO service can disable a lost vehicle key and program the replacement key fob.
One or more replacement key fobs can be programmed.

This may happen when you are in an area with low signal strength. Turn off your
device if is not in use.
C. When you cannot turn on the tablet:
Make sure the tablet is connected to a power source or the battery is charged.
D. When you are unable to charge the tablet:
 Your charger may be out of order. Contact your nearest dealer.
 You may be attempting to use the device in an overly hot/cold temperature. Try
changing the charging environment.
 Your device may have not been connected to the charger properly. Check the
connector.

NOTE
If your problems persist, please contact Autel’s technical support personnel or your local
selling agent.

16.3 About Battery Usage

Your tablet is powered by a built-in Lithium-ion Polymer battery. This means that, unlike
other forms of battery technology, you can recharge your battery while some charge
remains without reducing your tablet’s autonomy due to the “battery memory effect”
inherent in those technologies.

DANGER
The built-in Lithium-ion Polymer battery is factory replaceable only; incorrect replacement
or tampering with the battery pack may cause an explosion.
Do not use a damaged battery charger.

 Do not disassemble or open crush, bend or deform, puncture or shred.

 Do not modify or remanufacture, attempt to insert foreign objects into the battery,
expose to fire, explosion or other hazard.

78
  Make sure to use the charger and USB cables only that come together in the
package. If you use the other charger and USB cables, you might incur malfunction
or failure of the device.
 Only use the charging device that has been qualified with device per the standard.
Use of an unqualified battery or charger may present a risk of fire, explosion, leakage,
or other hazard.
 Avoid dropping the tablet. If the tablet is dropped, especially on a hard surface, and
the user suspects damage, take it to a service center for inspection.
 The closer you are to your network’s base station, the longer your tablet usage time
because less battery power is consumed for the connection.
 The battery recharging time varies depending on the remaining battery capacity.
 Battery life inevitably shortens over time.
 Since over charging may shorten battery life, remove the tablet from its charger once
it is fully charged. Unplug the charger, once charging is complete.
 Leaving the tablet in hot or cold places, especially inside a car in summer or winter,
may reduce the capacity and life of the battery. Always keep the battery within normal
temperatures.

exempt RSSs. Operation is subject to the following two conditions:

1. This device may not cause harmful interference.

2. This device must accept any interference received, including interference that may
cause undesired operation.

Cet appareil est conforme aux CNR exempts de licence d’Industrie Canada. Son
fonctionnement est soumis aux deux conditions suivantes:

1. Ce dispositif ne peut causer des interferences; et

2. Ce dispositif doit accepter toute interférence, y compris les interférences qui peuvent
causer un mauvais fonctionnement de l’appareil.

WARNING
Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.

NOTE
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation.

This equipment generates uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not occur
in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:

-- Reorient or relocate the receiving antenna.

-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help.

82
Changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.

SAR

The radiated output power of this device is below the FCC radio frequency exposure limits.
Nevertheless, the device should be used in such a manner that the potential for human
contact is minimized during normal operation.

The exposure standard for wireless devices employs a unit of measurement known as the
Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 W/Kg. Tests for
SAR are conducted using standard operating positions accepted by the FCC with the
device transmitting at its highest certified power level in all tested frequency bands.

Although the SAR is determined at the highest certified power level, the actual SAR level
of the device while operating can be well below the maximum value. This is because the
device is designed to operate at multiple power levels so as to use only the power required
to reach the network. To avoid the possibility of exceeding the FCC radio frequency
exposure limits, human proximity to antenna should be minimized.

RF WARNING STATEMENT

The device has been evaluated to meet general RF exposure requirement. The device
can be used in portable exposure condition without restriction.

The term “IC” before the radio certification number only signifies that IC technical
specifications were met.

RoHS COMPLIANCE

This device is declared to be in compliance with the European RoHS Directive

2011/65/EU.

CE COMPLIANCE

This product is declared to conform to the essential requirements of the following

Directives and carries the CE mark accordingly:

RED Directive 2014/53/EU
