METER / GAUGE SYSTEM Odo/Trip Switch Malfunction

DESCRIPTION

In this circuit, the combination meter assembly receives an ODO/TRIP switch signal from the trip switch using the direct line.

Tech Tips

The whole trip switch should be replaced if the ODO/TRIP switch has a malfunction because this part is not independently supplied.

INSPECTION PROCEDURE

PROCEDURE


  1. READ VALUE USING INTELLIGENT TESTER (ODO/TRIP CHANGE SW)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the tester on.

    4. Enter the following menus: Body / Combination Meter / Data List.

    5. Check the values by referring to the table below.

      Combination Meter
      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      ODO/TRIP Change SW ODO/TRIP change switch condition OFF: ODO/TRIP change switch released -
      ON: ODO/TRIP change switch pressed -
      OK
      ODO/TRIP switch condition displayed on the tester changes with the actual switch operation.

  2. CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - TRIP SWITCH)


    1. A01CG7PE06

      Disconnect the G19 and G32 connectors.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      G19-17 (ODO) - G32-7 (+) Always Below 1 Ω
      G32-7 (+) - Body ground Always 10 kΩ or higher
      G32-4 (E) - Body ground Always Below 1 Ω

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  3. INSPECT TRIP SWITCH (ODO/TRIP SWITCH)


    1. A01CDSSE01

      Remove the trip switch Click here.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      4 (E) - 7 (+) ODO/TRIP switch is pressed Below 1 Ω
      4 (E) - 7 (+) ODO/TRIP switch is released 10 kΩ or higher

    3. Apply battery voltage from the wire harness back side between the terminals of the switch, and check the lighting condition of the trip switch.

      OK
      Tester Connection Condition Specified Condition

      Battery positive (+) → 8 (ILL+)

      Battery negative (-) → 4 (E)

      		 Always Trip switch illuminates
