INSPECTION PROCEDURE

PROCEDURE


  1. INSPECT FUSE (ECU-IG & GAUGE)


    1. Remove the ECU-IG & GAUGE fuse from the instrument panel junction block.

    2. Measure the resistance of the fuse.

      Standard resistance
      Below 1 Ω

    NG

    REPLACE FUSE

    OK

  2. INSPECT IG1 RELAY (Marking: IG1)

    A01J7M3E02

    1. Remove the IG1 relay from the No. 3 relay block.

    2. Measure the resistance of the relay.

      Standard resistance
      Tester Connection Specified Condition
      3 - 5 10 kΩ or higher
      3 - 5

      Below 1 Ω

      (when battery voltage is applied to terminals 1 and 2)

    NG

    REPLACE IG1 RELAY

    OK

  3. INSPECT IGNITION SWITCH ASSEMBLY

    A01J7H4E01

    1. Remove the ignition switch.

    2. Measure the resistance of the switch.

      Standard resistance
      Tester Connection Switch Position Specified Condition
      1 (IG1) - 4 (AM1) OFF 10 kΩ or higher
      1 (IG1) - 4 (AM1) ON Below 1 Ω

    NG

    REPLACE IGNITION SWITCH ASSEMBLY

    OK

  4. CHECK WIRE HARNESS (MASTER SWITCH - BATTERY AND BODY GROUND)

    A01J50DE06

    1. Disconnect the P6 master switch connector.

    2. Measure the voltage of the wire harness side connectors.

      Standard voltage
      Tester Connection Condition Specified Condition
      P6-6 (B) - Body ground Ignition switch ON 10 to 14 V

    3. Measure the resistance of the wire harness side connectors.

      Standard resistance
      Tester Connection Specified Condition
      P6-3 (E) - Body ground Below 1 Ω

    NG

    REPAIR OR REPLACE HARNESS AND CONNECTOR

    OK

    REPLACE POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY
