6: Yaw Rate/Side G Sensor and Circuit Between Yaw Rate/Side G Sensor and VDC/TCS/ABS Control Unit
Inspection 6: Yaw Rate/Side G Sensor and Circuit Between Yaw Rate/Side G Sensor and VDC/TCS/ABS Control UnitCAUTION: Sudden turns (such as spin turns, acceleration turns), drifting, etc.; when VDC function is OFF (VDC OFF indicator lamp is turned on) may cause yaw rate/side G sensor circuit to indicate a malfunction.
However, this is not a malfunction, if normal operation can be resumed after restarting engine. Then erase memory of self-diagnosis.
Inspection Procedure
1. CHECK SELF-DIAGNOSTIC RESULTS (1)
Check the self-diagnostic results.
CAUTION: If vehicle is on turn-table at entrance to parking garage, or on other moving surface, VDC OFF indicator lamp may illuminate and CONSULT-II 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. And after doing spin turns or acceleration turns with VDC "OFF" (VDC OFF switch "ON"), too, the results will return to a normal state by re-starting vehicle.
Do "YAW RATE SENSOR " and "SIDE G-SEN CIRCUIT" appear on self-diagnosis display?
YES >> GO TO 2.
NO >> INSPECTION END
2. CHECK SELF-DIAGNOSTIC RESULTS (2)
1. Turn ignition switch OFF and disconnect yaw rate/side G sensor connector and VDC/TCS/ABS control unit connector. Then reconnect them securely.
2. Perform VDC/TCS/ABS control unit self-diagnosis again.
OK or NG
OK >> Poor connection of connectors. Repair or replace suspect connector. Perform self-diagnosis again.
NG >> GO TO 3.
3. CHECK YAW RATE/SIDE G SENSOR CIRCUIT
1. Turn ignition switch OFF and disconnect yaw rate/side G sensor connector and VDC/TCS/ABS control unit connector.
2. Check continuity between VDC/TCS/ABS control unit harness connector M93 and yaw rate/side G sensor harness connector M51.
OK or NG
OK >> GO TO 4.
NG >> Open or short in harness. Repair or replace the suspect harness.
4. PERFORM DATA MONITOR
1. Connect VDC/TCS/ABS control unit connector and yaw rate/side G sensor connector.
2. Check "DATA MONITOR" for yaw rate /side G sensor. Make sure results are normal.
OK or NG
OK >> Perform VDC/TCS/ABS control unit self-diagnosis again.
NG >> Malfunction of yaw rate/side G sensor. Replace yaw rate/side G sensor and perform VDC/TCS/ABS control unit self-diagnosis again.
