Diagnosis Procedure

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

1. CONNECTOR INSPECTION 
   1. Turn the ignition switch OFF.
   2. Disconnect the delta stroke 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. DELTA STROKE SENSOR CIRCUIT INSPECTION 
   1. Measure the continuity between ABS actuator and electric unit (control unit) connector E125 (A) and delta stroke sensor connector E114 (B).

      ABS actuator and electric unit (control unit)		Delta stroke sensor		Continuity
      Connector	Terminal	Connector	Terminal
      A: E125	26	B: E114	1	Yes
      	39		3
      	40		5

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

      ABS actuator and electric unit (control unit)		-	Continuity
      Connector	Terminal
      A: E125	26	Ground	No
      	39
      	40

      Is the inspection result normal? 

      YES: GO TO 3

      NO: Repair or replace harness or connector.

3. DELTA STROKE SENSOR INSPECTION 
   1. Reconnect the delta stroke sensor and ABS actuator and electric unit (control unit) connectors.
   2. Perform the delta stroke sensor component inspection. Refer to "COMPONENT INSPECTION ".

      Is the inspection result normal? 

      YES: Replace the ABS actuator and electric unit (control unit). Refer to "REMOVAL AND INSTALLATION ".

      NO: Replace the delta stroke sensor.
