STEERING ANGLE SENSOR CIRCUIT CHECK
1.
Disconnect the ESP/TCS/ABS control unit connector and the
steering angle sensor connector.
2.
Check for continuity between the ESP/TCS/ABS control unit
harness connector B109 and the steering angle sensor harness
connector M33.
Is inspection result OK?
OK
>> GO TO 4.
NG
>> Repair or replace the disconnected harness.
4.
DATA MONITOR CHECK
Perform the “STR ANGLE SIG” value in “DATA MONITOR” and check that it is in normal condition.
Is inspection result OK?
OK
>> Perform the ESP/TCS/ABS control unit self-diagnosis again.
NG
>> Replace the spiral cable (with the steering angle sensor) and adjust the neutral position of steer-
ing angle sensor.

Inspection procedure
1.
SELF-DIAGNOSIS RESULT CHECK 1
Check the self-diagnosis results.
CAUTION:
When the vehicle on a turn-table at an entrance of parking lot or on a moving unit, the ESP OFF indica-
tor lamp turns ON, and the self-diagnosis with CONSULT-II may indicate that the yaw rate sensor sys-
tem is malfunction. In this case, the yaw rate sensor is not malfunction. Move the vehicle from the
turn-table or other moving unit, and restart the engine. This will return the status normal.
Are “YAW RATE SENSOR” and “SIDE G-SEN CIRCUIT” indicated in the self-diagnosis results.

TROUBLE DIAGNOSIS
2.
SELF-DIAGNOSIS RESULT CHECK 2
1.
Disconnect connectors of the yaw rate/side G sensor and the
ESP/TCS/ABS control unit.
2.
Check for continuity between the ESP/TCS/ABS control unit
harness connector B109 and the yaw rate/side G sensor har-
ness connector B115.
Is inspection result OK?
OK
>> GO TO 3.
NG
>> Repair or replace the disconnected harness.
3.
YAW RATE SENSOR / SIDE G SENSOR CIRCUIT CHECK
Check that the “YAW RATE SEN” and the “SIDE G-SENSOR” are in normal operation in “DATA MONITOR”.
Is inspection result OK?
OK
>> Perform the ESP/TCS/ABS control unit self-diagnosis again.
NG
>> The yaw rate / side G sensor malfunction. After replacing the sensor, perform the self-diagnosis of
the ESP/TCS/ABS control unit again.
