Inspection 6: Yaw Rate/Side/Decel G sensor Circuit

CAUTION: Sudden turns (such as spin turns, acceleration turns), drifting, etc. may cause yaw rate/side/decal G sensor circuit indicate a malfunction. However this is not a malfunction if normal operation can be resumed after restarting engine.

INSPECTION PROCEDURE
1. CHECK SELF-DIAGNOSTIC RESULTS





Check self-diagnostic results.





CAUTION: When on a turntable, such as at a parking structure entrance, or when on a moving object with engine running, the VDC OFF indicator lamp might turn on and self-diagnosis using the CONSULT-II yaw rate sensor system malfunction might be displayed, but in this case there is no malfunction with yaw rate/side/decal G sensor circuit. As soon as the vehicle leaves the turntable or moving object, restart engine to return the system 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 restarting vehicle.

Is above displayed in self-diagnosis display items?
YES >> GO TO 2.
NO >> INSPECTION END

2. CHECK CONNECTOR
1. Disconnect yaw rate/side/decal G sensor connector M61 and ABS actuator and electric unit (control unit) connector E24 and check terminals for deformation, disconnection, looseness, and so on. If there is an error, repair or replace terminal.
2. Reconnect connectors and perform a ABS actuator and electric unit (control unit) self-diagnosis again

OK or NG
OK >> Connector terminal contact is loose, damaged, open or shorted.
NG >> GO TO 3.

3. CHECK YAW RATE SENSOR/SIDE G SENSOR HARNESS





1. Turn ignition switch OFF and disconnect yaw rate/side/decal G sensor connector M61 and ABS actuator and electric unit (control unit) connector E24.





2. Check continuity between ABS actuator and electric unit (control unit) vehicle side connector and yaw rate/side/decal G sensor vehicle side connector.

OK or NG
OK >> GO TO 4.
NG >> If open or short in harness, repair or replace harness.

4. CHECK YAW RATE SENSOR/SIDE/DECEL G SENSOR
1. Connect yaw rate /side/decal G sensor M61 and ABS actuator and electric unit (control unit) connector E24.





2. Use "Data Monitor" to check if yaw rate sensor/side/decal G sensor are normal.

OK or NG
OK >> Perform ABS actuator and electric unit (control unit) self diagnosis again
NG >> Replace the malfunctioning yaw rate sensor/side/decal G sensor, and then perform ABS actuator and electric unit (control unit) self-diagnosis again
