INSPECTION PROCEDURE

PROCEDURE


  1. INSPECT HEADLIGHT DIMMER SWITCH (TURN SIGNAL SWITCH)


    1. A015CPQE02

      Remove the headlight dimmer switch Click here.

    2. for LH Side:

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      13 (TR) - 12 (EL) Turn signal switch right turn Below 1 Ω
      Turn signal switch off 10 kΩ or higher
      15 (TL) - 12 (EL) Turn signal switch left turn Below 1 Ω
      Turn signal switch off 10 kΩ or higher
    3. A015DMNE01

      for RH Side:

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      16 (TR) - 19 (EL) Turn signal switch right turn Below 1 Ω
      Turn signal switch off 10 kΩ or higher
      18 (TL) - 19 (EL) Turn signal switch left turn Below 1 Ω
      Turn signal switch off 10 kΩ or higher

    NG
    OK
  2. CHECK HARNESS AND CONNECTOR (HEADLIGHT DIMMER SWITCH - TURN SIGNAL FLASHER AND BODY GROUND)


    1. A0159J2E02

      Disconnect the E14 switch connector.

    2. Disconnect the E19 relay connector.

    3. for LH Side:

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      E14-13 (TR) - E19-6 (ER) Always Below 1 Ω
      E14-15 (TL) - E19-5 (EL)
      E14-12 (EL) - Body ground
      E14-13 (TR) - Body ground Always 10 kΩ or higher
      E14-15 (TL) - Body ground
    4. A0159J2E01

      for RH Side:

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

      Standard Resistance
