CHECK REAR WIPER MOTOR OUTPUT VOLTAGE

  1. Connect BCM connector.

  2. Rear wiper switch OFF, and wait for 1 minute or more.

  3. Disconnect rear wiper motor connector.

  4. Ignition switch ON.

  5. With operating rear wiper switch, check voltage between rear wiper motor harness connector and ground.

    (+) (−) Condition

    Voltage

    (Approx.)
    Rear wiper motor
    Connector Terminal
    D506 1 Ground Rear wiper switch ON

    Battery voltage

    (5 seconds*)

    *: When rear wiper motor connector is disconnected and rear wiper switch is ON for more than 5 seconds, BCM stops the power supply according to rear wiper motor protection function. To perform the check again, turn rear wiper switch OFF, wait for 1 minute or more, and then perform the check.

Is the inspection result normal?

YES>>

GO TO 5.

NO>>

GO TO 4.
