Inspection 6 Yaw Rate/Side/Decel G Sensor System

WARNING: This page is about a different car, the 2003 Nissan Murano. However, it is still accessible from the selected car via links, so may be relevant.

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

INSPECTION PROCEDURE

CHECK SELF-DIAGNOSIS RESULT
Check self-diagnosis 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 problem with yaw rate/side/ decel G sensor system. As soon as the vehicle leaves the turntable or moving object, restart engine to return the system to normal.

Is Above Displayed In Self-Diagnosis Display Items?
1. YES: GO TO 2.
2. NO: Inspection END
CHECK CONNECTOR
1. Disconnect yaw rate/side/decel 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 re-conduct a ABS actuator and electric unit (control unit) self-diagnosis.
OK or NG
1. OK: Connector terminal contact is loose, damaged, open or shorted.
2. NG: GO TO 3.
CHECK YAW RATE SENSOR/SIDE G SENSOR HARNESS
1. Turn ignition switch OFF and disconnect yaw rate/side/decel 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/decel G sensor vehicle side connector.

OK or NG
1. OK: GO TO 4.
2. NG: If open or short in harness, repair or replace harness.
CHECK YAW RATE SENSOR/SIDE/DECEL G SENSOR
1. Connect yaw rate /side/decel G sensor M61 and ABS actuator and electric unit (control unit) connector E24.
2. Use Data Monitor to check if yaw rate sensor/side/decel 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/decel G sensor, and then re-conduct ABS actuator and electric unit (control unit) self-diagnosis.
