INSPECTION PROCEDURE

PROCEDURE


  1. CHECK TCM (IG2 VOLTAGE)


    1. A01DYIIE09

      Turn the ignition switch ON.

    2. Measure the voltage of the TCM connectors.

      Standard voltage
      Tester Connection Specified Condition
      T38-6 (IG2) - T19-1 (E1) 9 to 14 V

    OK

    PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE

    NG

  2. CHECK WIRE HARNESS (TCM - BODY GROUND)


    1. A01DWWJE08

      Disconnect the T19 TCM connector.

    2. Measure the resistance of the wire harness side connector.

      Standard resistance
      Tester Connection Specified Condition
      T19-1 (E1)- Body ground Below 1 Ω

    NG

    REPAIR OR REPLACE HARNESS AND CONNECTOR

    OK

  3. INSPECT FUSE (IGN)


    1. A01E308E01

      Remove the IGN fuse from the instrument panel junction block.

    2. Measure the resistance of the fuse.

      Standard resistance
      Below 1 Ω

    NG

    REPLACE FUSE

    OK

  4. INSPECT IGNITION SWITCH


    1. A01DV3BE04

      Disconnect the I6 ignition switch connector.

    2. Measure the resistance of the ignition switch.

      Standard resistance
      Tester Connection Switch Condition Specified Condition
      5 (AM2) - 6 (IG2) LOCK 10 kΩ or higher
      5 (AM2) - 6 (IG2) ON Below 1 Ω

    NG

    REPLACE IGNITION SWITCH

    OK

    REPAIR OR REPLACE HARNESS AND CONNECTOR (BATTERY - IGNITION SWITCH, IGNITION SWITCH - TCM)
