Entire Combination Meter does not Operate: Procedure

  1. INSPECT FUSE (GAUGE2, ECU-B, IG2) 
    1. Remove the GAUGE2 fuse from the instrument panel junction block.
    2. Remove the ECU-B fuse from the engine room No. 2 relay block.
    3. Remove the IG2 fuse from the engine room No. 1 relay block.
    4. Measure the resistance of the fuses.

      Standard resistance 

      Below 1 Ω

    NG → REPLACE FUSE 

    OK: Go to next step 

  2. INSPECT IG2 RELAY 
    1. Remove the IG2 relay from the No. 1 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 IG2 RELAY 

    OK: Go to next step 

  3. CHECK WIRE HARNESS (COMBINATION METER - BATTERY AND BODY GROUND) 
    1. Disconnect the E19 meter connector.

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

      Standard voltage 

      Tester Connection Condition Specified Condition
      E19-22 (B) - Body ground Always 11 to 14 V
      E19-21 (IG+) - Body ground Ignition switch ON 11 to 14 V
    3. Measure the resistance of the wire harness side connector.

      Standard resistance 

      Tester Connection Specified Condition
      E19-33 (ET) - Body ground Below 1 Ω

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK → REPLACE COMBINATION METER ASSEMBLY
