Diagnosis Procedure

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

1. CHECK REAR WIPER MOTOR OUTPUT VOLTAGE

   WITH CONSULT ACTIVE TEST

   1. Turn the ignition switch OFF.
   2. Disconnect rear wiper motor.
   3. Turn the ignition switch ON.
   4. Select "RR WIPER" of BCM (WIPER) active test item.
   5. While operating the test item, check voltage between BCM harness connector and ground.

      Terminals			Test item	Voltage (Approx.)
      (+)		(-)
      BCM			REAR WIPER
      Connector	Terminal
      M19	55	Ground	ON	Battery voltage
      			OFF	0V

      Is the measurement value normal? 

      YES: GO TO 2

      NO: GO TO  3

2. CHECK REAR WIPER MOTOR GROUND CIRCUIT
   1. Turn the ignition switch OFF.
   2. Check continuity between rear wiper motor harness connector and ground.

      Rear wiper motor		Ground	Continuity
      Connector	Terminal
      D602	1		Yes

      Does continuity exist? 

      YES: Replace rear wiper motor. Refer to "REMOVAL AND INSTALLATION ".

      NO: Repair or replace harness.

3. CHECK GLASS HATCH AJAR SWITCH CIRCUIT
   1. Disconnect BCM.
   2. Turn ignition switch OFF.
   3. Make sure glass hatch is closed
   4. Check continuity between BCM harness connector and ground.

      BCM		Ground	Continuity
      Connector	Terminal
      M19	42		No

      Does continuity exist? 

      YES: Repair harness if shorted. If not, refer to "DIAGNOSIS PROCEDURE " (with Intelligent Key system) or "DIAGNOSIS PROCEDURE " (without Intelligent Key system).

      NO: GO TO 4

4. CHECK REAR WIPER MOTOR OPEN CIRCUIT
   1. Check continuity between BCM harness connector and rear wiper motor harness connector.

      BCM		Rear wiper motor		Continuity
      Connector	Terminal	Connector	Terminal
      M19	55	D602	4	Yes

      Does continuity exist? 

      YES: GO TO 5

      NO: Repair or replace harness.

5. CHECK REAR WIPER MOTOR SHORT CIRCUIT

   Check continuity between BCM harness connector and ground.

   BCM		Ground	Continuity
   Connector	Terminal
   M19	55		No
