Diagnosis Procedure

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

1. CONNECTOR INSPECTION 
   1. Turn ignition switch OFF.
   2. Disconnect ABS actuator and electric unit (control unit) and VDC OFF switch connectors.
   3. Check connectors and terminals for deformation, disconnection, looseness or damage.

      Is the inspection result normal? 

      YES: GO TO 2.

      NO: Repair or replace as necessary.

2. CHECK VDC OFF SWITCH 

   Check VDC OFF switch. Refer to "COMPONENT INSPECTION ".

   Is the inspection result normal? 

   YES: GO TO 3.

   NO: Replace VDC OFF switch. Refer to "REMOVAL AND INSTALLATION ".

3. CHECK VDC OFF SWITCH SIGNAL 

   With CONSULT.

   1. Connect ABS actuator and electric unit (control unit) and VDC OFF switch connectors.
   2. Turn ignition switch ON.
   3. In "DATA MONITOR" select "OFF SW" and check VDC OFF switch signal.

      Condition	DATA MONITOR
      VDC OFF switch is pressed and released	On
      VDC OFF switch is pressed and released again	Off

      Is the inspection result normal? 

      YES: Refer to "WORK FLOW ".

      NO: GO TO 4.

4. CHECK VDC OFF SWITCH CIRCUIT 
   1. Turn ignition switch OFF.
   2. Disconnect ABS actuator and electric unit (control unit) and VDC OFF switch connectors.
   3. Check continuity between ABS actuator and electric unit (control unit) connector E33 terminal 15 and VDC OFF switch connector M64 terminal 6.

      ABS actuator and electric unit (control unit)		VDC OFF switch		Continuity
      Connector	Terminal	Connector	Terminal
      E33	15	M64	6	Yes

   4. Check continuity between ABS actuator and electric unit (control unit) connector terminal E33 terminal 15 and ground.

      ABS actuator and electric unit (control unit)		-	Continuity
      Connector	Terminal
      E33	15	Ground	No

      Is the inspection result normal? 

      YES: GO TO 5.

      NO: Repair or replace malfunctioning components.

5. CHECK VDC OFF SWITCH GROUND CIRCUIT 

   Check continuity between VDC OFF switch connector M64 terminal 8 and ground.

   VDC OFF switch		-	Continuity
   Connector	Terminal
   M64	8	Ground	Yes

   Is the inspection result normal? 

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

   NO: Repair or replace malfunctioning components.
