Inspection Procedure

Check self-diagnosis results.

Is above displayed on the self-diagnosis display? 

YES: GO TO 2.

No: INSPECTION END

1. Turn ignition switch OFF and disconnect yaw rate/side G sensor connector M145 and ABS actuator and electric unit (control unit) connector E30, check terminal for deformation, disconnection, looseness, and so on. If any malfunction is found, repair or replace terminal.
2. Reconnect connector and perform self-diagnosis.

OK or NG 

OK: INSPECTION END

NG: GO TO 3.

1. Turn ignition switch OFF and disconnect yaw rate/side G sensor connector M155.
2. Turn ignition switch ON or OFF and check voltage between yaw rate/side G sensor harness connector M155 and ground.
   VOLTAGE SPECIFICATION
   
   

   Yaw rate/side G sensor (harness connector M155)	Ground	Measurement condition	Measure value
   4	-	Ignition switch ON	Battery voltage (Approx. 12 V)
   		Ignition switch OFF	Approx. 0 V

OK or NG 

OK: GO TO 4.

NG:

• Repair or replace malfunctioning components.
• Perform the self-diagnosis, and make sure that the result shows "NO DTC IS DETECTED".

1. Turn ignition switch OFF and disconnect Yaw rate/side G sensor connector M145 and ABS actuator and electric unit (control unit) connector E30.
2. Check continuity between Yaw rate/side G sensor harness connector M145 and ABS actuator and electric unit (control unit) harness connector E30.
   CONTINUITY SPECIFICATION
   
   

   ABS actuator and electric unit (control unit)	Yaw rate/side G sensor	Continuity
   1	-	Yes

OK or NG 

OK: GO TO 5.

NG:

• Repair or replace malfunctioning components.
• Perform the self-diagnosis, and make sure that the result shows "NO DTC IS DETECTED".

1. Disconnect yaw rate/side G sensor connector M155 and ABS actuator and electric unit (control unit) connector E30.
2. Check continuity between yaw rate/side G sensor harness connector terminals and ABS actuator and electric unit (control unit) harness connector terminals.
   YAW RATE SEN (DATA MONITOR)
   
   

   Yaw rate/side G sensor (Harness connector M155	YAW RATE SEN (DATA MONITOR)	Continuity
   2	25	Yes
   3	45

OK or NG 

OK: GO TO 6.

NG: Repair or replace malfunctioning components.

1. Connect the Yaw rate/side G sensor connector and ABS actuator and electric unit (control unit) connector.
2. Select "YAW RATE SEN", "SIDE G-SENSOR" in "DATA MONITOR" and check yaw rate/side G sensor signal.

OK or NG 

OK:

• Replace ABS actuator and electric unit (control unit).
• Perform the self-diagnosis, and make sure that the result shows "NO DTC IS DETECTED".

NG:

• Replace yaw rate/side G sensor.
• Perform the self-diagnosis, and make sure that the result shows "NO DTC IS DETECTED".
