1. Check for DTCs of the SFI system (1TR-FE, 2TR-FE, 1GR-FE) or ECD system (1KD-FTV, 2KD-FTV).

   Result:

     Result | Proceed to
     DTC is not output | A
     DTC is output | B

| B |

GO TO SFI SYSTEM (1TR-FE, 2TR-FE, 1GR-FE), ECD SYSTEM (1KD-FTV, 2KD-FTV)

2.CHECK WIRE HARNESS (COMBINATION METER ASSEMBLY - ECM)

1. Disconnect the C8 meter connector.

1. Disconnect the E10*1, E13*2 or E5 *3 ECM connector.

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

   Standard resistance:

     1TR-FE, 2TR-FE
     Tester Connection | Specified Condition
     C8-4 - E10-14 (THWO) | Below 1 Ω

   1GR-FE:

     Tester Connection | Specified Condition
     C8-4 - E13-14 (THWO) | Below 1 Ω

   1KD-FTV, 2KD-FTV:

     Tester Connection | Specified Condition
     C8-4 - E5-2 (THWO) | Below 1 Ω

   HINT:
     *1: 1TR-FE, 2TR-FE
     *2: 1GR-FE
     *3: 1KD-FTV, 2KD-FTV
