Diagnosis Procedure (Rear Pressure Sensor)

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM ".

1. CONNECTOR INSPECTION 
   1. Turn the ignition switch OFF.
   2. Disconnect the rear pressure sensor connector and ABS actuator and electric unit (control unit) connector and inspect the terminals for deformation, disconnection, looseness, or damage.

      Is the inspection result normal? 

      YES: GO TO 2

      NO: Repair connector.

2. REAR PRESSURE SENSOR CIRCUIT INSPECTION 
   1. Measure the continuity between the ABS actuator and electric unit (control unit) connector E125 (A) and rear pressure sensor connector E32 (B).

      ABS actuator and electric unit (control unit)		Rear pressure sensor		Continuity
      Connector	Terminal	Connector	Terminal
      E125 (A)	21	E32 (B)	1	Yes
      	22		3
      	23		2

   2. Measure the continuity between the ABS actuator and electric unit (control unit) connector E125 (A) and body ground.

      ABS actuator and electric unit (control unit)		-	Continuity
      Connector	Terminal
      E125 (B)	21	Ground	No
      	22
      	23

      Is the inspection result normal? 

      YES: GO TO 3

      NO: Repair or replace harness or connector.

3. REAR PRESSURE SENSOR INSPECTION 
   1. Reconnect the rear pressure sensor and ABS actuator and electric unit (control unit) connectors.
   2. Perform PRESS SEN2 component inspection. Refer to "COMPONENT INSPECTION (REAR PRESSURE SENSOR) ".

      Is the inspection result normal? 

      YES: Inspection End.

      NO: Replace the rear pressure sensor.
