Diagnosis Procedure

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

1. CHECK FRONT WASHER MOTOR FUSE 
   1. Turn the ignition switch OFF.
   2. Check that the following fuse is not blown.

      Unit	Location	Fuse No.	Capacity
      Front washer motor	Fuse block (J/B)	9	10A

      Is the fuse blown? 

      YES: Replace the fuse after repairing the affected circuit.

      NO: GO TO 2

2. CHECK WIPER AND WASHER SWITCH INPUT VOLTAGE 
   1. Disconnect combination switch (wiper and washer switch).
   2. Turn the ignition switch ON.
   3. Check voltage between combination switch (wiper and washer switch) harness connector and ground.

      Terminals			Voltage (Approx.)
      (+)		(-)
      Combination switch (wiper and washer switch)		Ground
      Connector	Terminal
      M28	14		Battery voltage

      Is the measurement value normal? 

      YES: GO TO 3

      NO: Repair or replace harness.

3. CHECK WIPER AND WASHER SWITCH GROUND CIRCUIT 

   Check continuity between combination switch (wiper and washer switch) harness connector and ground.

   Combination switch (wiper and washer switch)		Ground	Continuity
   Connector	Terminal
   M28	12		Yes

   Does continuity exist? 

   YES: GO TO 4

   NO: Repair or replace harness.

4. CHECK FRONT AND REAR WASHER MOTOR POWER SUPPLY 
   1. Turn ignition switch OFF.
   2. Connect combination switch (wiper and washer switch), disconnect front and rear washer motor.
   3. Turn ignition switch ON.
   4. Check voltage between front and rear washer motor harness connector and ground.

      Terminal			Condition		Voltage (V) (Approx.)
      (+)		(-)
      Front and rear washer motor	Terminal
      E105	1	2	Washer switch	Front: ON	Battery voltage
      	2	1		Rear: ON

      Is the measurement value normal? 

      YES: Replace front and rear washer motor. Refer to "WASHER MOTOR ".

      NO: Repair or replace harness.
