 02 - INTRODUCTION

Circuit Simulation Test

The non-regular malfunctions and other malfunctions that cannot be detected through a road test can be
detected by circuit simulation test. The possible vehicle malfunction can be determined efficiently by
simulating condition/environment when the malfunction occurs.
Simulation test can be classified into the following 7 types:
 Vehicle vibration test
 Thermosensitive test
 Freezing test 02
 Leakage test
 Load test
 Cold/hot start test
 Voltage drop test
HINT:
It is extremely important to listen carefully to customer's description about the malfunction for simulating the
conditions when the symptoms occur.
1. Vehicle vibration test
When the vehicle is running on an uneven road or the engine is vibrating (A/C is on and engine is idling),
malfunctions may occur. In this case, check the conditions related to vibration. Check the following areas
on vehicle:
a. Connector and wire harness
Determine the connectors and wire harnesses that
may affect the electrical system being inspected. Slightly Vibrate

When monitoring whether the system has

malfunctions that are being simulated, vibrate or
wiggle each connector and wire harness slightly. This
test may show loose or poor electrical connections.

Slightly Vibrate
Slightly Wiggle
RT21020170

HINT:
When connector is exposed to humid environment, a layer of corrosive film may form on its terminals.
With the connector connected, this condition may not be found by visual check.If an intermittent
malfunction occurs, it may be caused by corrosion. It is recommended that the terminals of relevant
connectors in the system should be checked and cleaned after disconnecting the connectors.
b. Sensors and relays.
Slightly vibrate the sensors and relays that you want to check in the system. The sensors or relays that
are loose or poorly installed may be found through this test.

Chery Automobile Co., Ltd. 02–17

 02 - INTRODUCTION

c. Engine compartment
 There are many reasons for the electrical malfunction that occurred due to vehicle vibration, and it is
necessary to check the following conditions:
- Connectors are not installed correctly.
- Wire harness is not long enough, so it is extended when engine is vibrating or shaking.
- Wire harness hangs over the bracket or movable components.
- Ground wire is loose, dirty or corrosive.
02 - Wire harness is too close to the high temperature components.
 To inspect the components under the engine hood, first confirm that the ground connection is in
perfect condition (refer to the grounding inspection described below). First confirm that the system is
correctly grounded. Then slightly vibrate the wire harness or components as previously instructed to
check if the connection is loose. Refer to the circuit diagram to check the continuity of wire harness.
d. Backside of instrument panel
 Improper wire clamping will cause the wire harnesses to be entangled when installing accessories.
The vibration of vehicle will cause the wire harnesses near the bracket or mounting screw to wind
excessively.
 When vehicle vibrates, unclamped or loose wire harness will be stuck in the seat components (such
as slide guide). When wire harness passes through the underside of mounting area, check if it is
damaged or stuck.
2. Thermosensitive test
In hot weather or after the vehicle is parked for a short time, the user may worry about the vehicle
condition. At this time, it is necessary to perform thermosensitive test.
Perform test by heating components with a heat gun or equivalent.

CAUTION

 DO NOT heat components to a temperature higher than 60°C (140°F).

 Perform test by heating components with a heat gun or equivalent.

3. Freezing test
If malfunction disappears after warming up the vehicle in winter, it may be caused by freeze of some parts
in the wire harness/electrical system. Use the following two methods to check this condition:
Method 1: Put vehicle outdoors overnight. Make sure that the temperature is low enough to duplicate the
malfunction. Perform a quick and thorough diagnosis on the component that may be affected in the
morning.
Method 2: Put suspected part in refrigerating room and wait until it is frozen. Reinstall the component to
vehicle and check if malfunction reoccurs. If malfunction occurs, repair or replace the component.
4. Leakage test
Malfunction may occur only during high humidity or in
rainy or snowy weather. In this case, malfunction may
occur due to water entering electrical parts. Leakage can
be checked by spraying water to vehicle (similar to car
wash).

RT21020180

02–18 Chery Automobile Co., Ltd.

 02 - INTRODUCTION

5. Load test
Malfunction occurs only when electrical device is turned
on. Turn on the electrical equipment (A/C, rear window
defogger, radio, fog light, etc.) one by one and determine
the relationship between electrical equipment and
malfunction. Confirm the malfunction by a load test.

02
RT21020190

6. Cold/hot start test

Some malfunctions occur in cold start and disappear when engine warms up. In this case, park vehicle
without operation for a whole night and restart it the next day. Perform test and determine the cause
quickly.
7. Voltage drop test
Generally, the voltage drop test is used to find out the possible causes that affect the normal function of
electrical components or circuits.
Check the circuit with a digital multimeter.
If resistance of single wire harness measured by a digital multimeter is very low (0 Ω or close to 0 Ω), the
wire harness or circuit is normal.
The unnecessary resistance in circuit may be caused by poor, loose grounding, corrosive switch contact
and loose wire connector or adapter.

Precautions for Control Module and Electrical Components

Inspection
 Before performing electrical operations, turn ignition
switch to LOCK and disconnect the negative battery
cable, then wait for 2 minutes until the backup power
supply of airbag module is depleted (w/ airbag system).

RT21020200

 Disconnecting the battery cable will delete the clock, audio and DTC records. Therefore, it is necessary to
confirm these records before disconnecting the cable.
 Never connect the electrodes of battery terminals reversely.
 Only install components that meet the vehicle specifications.
1. Inspect input and output conditions of components and their functions before replacing control module.
 When disconnecting components:
- Do not use excessive force when disconnecting connector.
- If connector is installed by tightening bolt, loosen mounting bolt and then disconnect the connector
by hand.
 When connecting components:
- Make sure that terminals are not bent or damaged, and then connect it correctly before installing
connector.

Chery Automobile Co., Ltd. 02–19

 02 - INTRODUCTION

- Tighten the mounting bolt until the painted area of connector is flush with the surface when installing
connector by tightening bolt.
 Never drop or hit the control module to prevent excessive impact.
 Note that the condensation is not formed on control module due to extreme change of temperature and
keep it free from water drop or rain. If water is found on the control module, dry it thoroughly and then
install it to vehicle.
 Be careful not to allow fluid to adhere to the control module connector.
 Avoid cleaning the control module with volatile fluid.
02
 When using digital multimeter, be careful not to get
the testing probes to contact with each other to result
in a short circuit. Avoid damaging the battery due to
short circuit in power transistor inside the control
module.

RT21020210

 Use specified test adapter to check the input and output signals of control module.
2. Check fuse
 Check that fuse wire is connected.

Good Blown

 The probe of digital multimeter may be connected incorrectly with the socket of connector. To detect the
connector correctly, use a "T" shaped pin and follow the procedures below. To obtain optimal
connection, clamp the "T" shaped needle with a spring clamp.
a. Detect from wire harness side
- If there is a back cover for connector, remove the back cover before detecting terminal.
- Do not detect the water-proof connector from the wire harness side. Failure to do this may
damage the seal between wire harness and connector.
b. Detect from terminal side
- Female terminal:
Do not insert any object that is bigger than male terminal into the female connector.
- Male terminal:
Carefully detect the contact surfaces of each terminal with a "T" shaped needle. Do not bend the
terminal.
2. Check terminal contact spring for proper tension
 The contact spring on terminal may produce intermittent signals in the circuit.
 If intermittent open circuit occurs, follow the procedures below to check open wire harness and contact
spring on the female terminal.
- Use a male terminal matched with female terminal.
- Disconnect the suspected defective connector and secure the terminal side upward.
- When securing the wire harness of male terminal, try to insert the male terminal into female terminal.
- Move connector and check if male terminal can be inserted easily.
