DTC CONFIRMATION PROCEDURE

1.

CHECK SELF-DIAGNOSIS RESULTS

Check the self-diagnosis results.

Is above displayed on the self-diagnosis display?

YES

>> Proceed to diagnosis procedure. Refer to 

BRC-155, "Diagnosis Procedure"

.

NO

>> Inspection End.

Diagnosis Procedure

INFOID:0000000007356868

Regarding Wiring Diagram information, refer to 

BRC-207, "Wiring Diagram - With VK56DE"

.

CAUTION:

• Sudden turns (such as spin turns, acceleration turns), drifting, etc. when VDC function is OFF may

cause the yaw rate/side/decel G sensor system to indicate a malfunction. This is not a malfunction if

normal operation can be resumed after restarting the engine.

• If vehicle is on turn table at entrance to parking garage, or on other moving surface, SLIP indicator

lamp may illuminate and CONSULT self-diagnosis may indicate yaw rate sensor system malfunction.

However, in this case there is no malfunction in yaw rate sensor system. Take vehicle off of turn

table or other moving surface, and start engine. Results will return to normal.

1.

CONNECTOR INSPECTION

1. Disconnect the ABS actuator and electric unit (control unit) connector and yaw rate/side/decel G sensor

connector. 

2. Check the terminals for deformation, disconnection, looseness or damage.
Is the inspection result normal?

YES

>> GO TO 2

NO

>> Repair or replace as necessary.

2.

YAW RATE/SIDE/DECEL G SENSOR HARNESS INSPECTION

Check continuity between the ABS actuator and electric unit (control unit) connector E127 and the yaw rate/

side/decel G sensor connector B73.
