PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (HEADLIGHT CLEANER CONTROL RELAY - BATTERY AND BODY GROUND)


    1. A01GY92E05

      Disconnect the A6 headlight cleaner control relay connector.

    2. Measure the voltage according to the value(s) in the table below.

      Standard voltage
      Tester Connection Switch Condition Specified Condition
      A6-3 (IG) - Body ground Power switch ON (IG) 11 to 14 V
      A6-3 (IG) - Body ground Power switch OFF Below 1 V

    3. Measure the resistance according to the value(s) in the table below.

      Standard resistance
      Tester Connection Condition Specified Condition
      A6-4 (E) - Body ground Always Below 1 Ω

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

      		 Headlight cleaner motor operation is normal

    NG

    REPLACE HEADLIGHT CLEANER MOTOR Click here

    OK

  3. CHECK HARNESS AND CONNECTOR (HEADLIGHT CLEANER MOTOR - HEADLIGHT CLEANER CONTROL RELAY AND BATTERY)


    1. A01H25CE02

      Disconnect the A92 headlight cleaner motor connector.

    2. Disconnect the A6 headlight cleaner control relay connector.

    3. Measure the voltage according to the value(s) in the table below.

      Standard voltage
      Tester Connection Condition Specified Condition
      A92-2 - Body ground Always 11 to 14 V

    4. Measure the resistance according to the value(s) in the table below.

      Standard resistance
      Tester Connection Condition Specified Condition
      A92-1 - A6-6 (PB) Always Below 1 Ω
      A92-1 - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK
