## WIRING DIAGRAM

## INSPECTION PROCEDURE

1.CHECK WIRE HARNESS (DLC3 - ECM AND BODY GROUND)

1. Disconnect the D1 DLC3 connector.

1. Disconnect the E14 or E5 ECM connector.

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

   Standard resistance:
     1GR-FE:

     Tester Connection | Specified Condition
     D1-13 (TC) - E14-23 (TC) | Below 1 Ω
     D1-13 (TC) - Body ground | 10 kΩ or higher
     D1-4 (CG) - Body ground | Below 1 Ω

     1KD-FTV:

     Tester Connection | Specified Condition
     D1-13 (TC) - E5-11 (TC) | Below 1 Ω
     D1-13 (TC) - Body ground | 10 kΩ or higher
     D1-4 (CG) - Body ground | Below 1 Ω
