1. Power door lock system function description

a. Power door lock system can lock/unlock all doors by wireless key, mechanical key, center control
switch and contact switch on the handle.
 Wireless key sends the lock/unlock request signals to Passive Entry & Passive Start (PEPS)
controller, which will control Body Control Module (BCM) via CAN line. Then, Body Control Module
(BCM) sends these request signals to the lock fastener of each door in order to lock/unlock all doors
simultaneously.
 After inserting mechanical key into the driver side door key cylinder, doors can be locked/unlocked
by turning the key clockwise or counterclockwise, but body anti-theft function cannot be set.
 Contact switch on handle: when the wireless key is outside the vehicle and within a 1.5 m semicircle
area around the front door handle, pressing the door handle switch can lock/unlock the doors.
 Contact switch on luggage compartment door: when the wireless key is outside the luggage
compartment door and within a 1.5 m semicircle area around the luggage compartment door handle,
pressing the door handle switch can unlock the luggage compartment door.
 Function active: effective at any time, even when engine starts.

 Lock success: when all doors are fully closed, input lock signal from center control switch, and
execute the lock command.
 Lock failure: when at least one door is not fully closed, input lock signal from center control switch,
execute the lock command, and then execute the unlock command after a 1 second delay.
 Unlock success: input the unlock signal from center control switch and execute lock command,
regardless of whether the doors are fully closed.
 Door lock response: when the protection is not activated, Body Control Module (BCM) responses to
each lock or unlock input.
 Door lock protection: lock then unlock the doors and repeat this sequence 4 times within 10 seconds
(Note: door lock then unlock = 1 sequence). Once the protection is activated, door lock function will
be disabled for 15 seconds. Before the disable function is activated, make sure that the final
command is unlock, rather than lock.

Diagnosis Tools
X-431 3G Diagnostic Tester
When connecting X-431 3G diagnostic tester:
 Connect X-431 3G diagnostic tester (the latest software) to Data Link Connector (DLC) for communication
with vehicle.
 DLC is located at the driver side instrument panel crossmember.
 DLC uses a trapezoidal design which can hold 16 terminals.

Digital Multimeter
When using a digital multimeter:
 Troubleshoot the electrical malfunctions and wire harness system.
 Troubleshoot the basic malfunction.
 Measure voltage, current and resistance.

Diagnostic Help
1. Connect X-431 3G diagnostic tester (the latest software) to Data Link Connector (DLC), and make it
communicate with vehicle electronic module through data network.
2. Confirm that malfunction is present, and carry out diagnostic test and repair procedures.
3. If DTC cannot be cleared, malfunction is present.
4. Only use a digital multimeter to measure the voltage of electronic system.
5. Refer to any Technical Bulletin that may apply to the malfunction.
6. Visually check the related wire harness.
7. Check and clean all the door lock system ground points related to the latest DTC.
8. If multiple trouble codes were set, use circuit diagrams and look for any common ground circuit or power
supply circuit applied to the DTC.

38–18 Chery Automobile Co., Ltd.

 38 - DOOR LOCK

Intermittent DTC Troubleshooting

If malfunction is intermittent, perform the followings:
 Check if connectors are loose.
 Check if wire harnesses are worn, pierced, pinched or partially broken.
 Wiggle related wire harnesses and connectors and observe if the signal is interrupted in the related circuit.
 If possible, try to duplicate the conditions under which DTC was set.
 Look for data that has changed or DTC to reset during wiggle test.
 Look for broken, bent, protruded or corroded terminals.
 Inspect the mounting areas of power door lock assembly, wire harnesses or wire harness connectors and
so on for damage, foreign matter, etc. that will cause incorrect signals.
 Check and clean all wire harness connectors and grounds related to the current DTC.
 Remove the Body Control Module (BCM) from malfunctioning vehicle and install it to a new vehicle and
perform a test. If DTC cannot be cleared, Body Control Module (BCM) is malfunctioning. If DTC can be
cleared, reinstall Body Control Module (BCM) to the original vehicle.
 If multiple trouble codes were set, refer to circuit diagrams to look for any common ground circuit or power
supply circuit applied to the DTC.
 Refer to any Technical Bulletin that may apply to the malfunction.

Ground Inspection
Groundings are very important to entire circuit system, which are normal or not can seriously affect the entire
circuit system. Groundings are often exposed to moisture, dirt and other corrosive environments. Corrosion
(rust) and oxidation may increase load resistance. This situation will seriously affect the circuit operation. 38
Perform the following operations when checking the ground points:
1. Remove the ground bolt or nut.
2. Check all contact surfaces for tarnish, dirt and rust, etc.
3. Clean as necessary to ensure that contacting is in good condition.
4. Reinstall the ground bolt or nut securely.
5. Check if add-on accessories interfere with ground circuit.
6. If several wire harnesses are crimped into one ground eyelet terminal, check for proper crimps. Make sure
all wire harnesses are clean, securely fastened to provide a good ground line.

Diagnosis Procedure
HINT:
Use following procedures to troubleshoot the power door lock control system.

1 Vehicle brought to workshop

NEXT

2 Check battery voltage

Standard voltage: 11 to 14 V
If voltage is below 11 V, recharge or replace the battery before proceeding to next step.

Confirm that battery voltage is between 11 to 14 V before performing following procedures.
 Turn ignition switch to LOCK.
 Connect X-431 3G diagnostic tester (the latest software) to Data Link Connector (DLC), and make it
communicate with vehicle electronic module through data network.
 Turn ignition switch to ON.
 Use X-431 3G diagnostic tester to record and clear DTCs stored in Body Control Module (BCM).
 Turn ignition switch to LOCK and wait for a few seconds.
 Turn ignition switch to ON, and then select Read Code.
 If DTC is detected, malfunction indicated by DTC is present. Go to Diagnosis Procedure - Step 1.
 If DTC is not detected, malfunction indicated by DTC is intermittent (See page 38-19).
