Work sequence





- Disconnect 8-pin harness connector -B-.
- Observe safety precautions.
- Check harness connector for contact corrosion and ingress of water.

If harness connector is not OK:
- Repair malfunction.
- Erase DTC memory of Transmission Control Module (TCM).
- Generate readiness code

If harness connector is OK:
- Check wires to Transmission Control Module (TCM) according to wiring diagram.

Checking wires to Transmission Control Module (TCM)
- Connect test box to control module wiring harnes.





- Check wires between test box and 8-pin connector to Transmission Control Module (TCM) for open circuit according to wiring diagram.
Terminal 3 + socket 51
Terminal 4 + socket 39
Wire resistance: max. 1.5 ohms

- Check wires for short circuit to each other.
Specified value: infinite ohms

If no malfunctions are found in wires:
- Replace Sensor for transmission RPM -G182-
- Erase DTC memory of Transmission Control Module (TCM).
- Generate readiness code.
