.

PROBABLE CAUSES

• The CAN bus line is defective.
• Malfunction of engine control module
• VIN not written
• Malfunction of AWC-ECU

DIAGNOSTIC PROCEDURE

STEP 1. Scan tool CAN bus diagnostics
Using scan tool MB991958, diagnose the CAN bus lines.
Q: Is the check result normal?

YES : Go to Step 2.
NO :  Repair the CAN bus lines. (Refer to GROUP 54C − 

Troubleshooting 

P.54C-15

.) After repairing the CAN 

bus line, go to Step 2.

the CAN bus lines are normal.

• Do not drop the G and yaw rate sensor or sub-

ject it to a shock.

• When G and yaw rate sensor is replaced, cali-

brate G and yaw rate sensor (refer to GROUP 
35C − On-vehicle Service 

P.35C-287

), and ini-

tialize the lateral/longitudinal acceleration 
correction amount stored in AWC-ECU. (Refer

self-diagnosis of the G and yaw rate sensor.

.

PROBABLE CAUSES

• Malfunction of G and yaw rate sensor
• Malfunction of AWC-ECU

DIAGNOSTIC PROCEDURE

STEP 1. Scan tool CAN bus diagnostics
Using scan tool MB991958, diagnose the CAN bus lines.
