DTC 25

DIAGNOSIS:
- Torque control signal is not emitted from TCM.
- The signal circuit Is open or shorted.

TROUBLE SYMPTCM: - Excessive shift shock

WIRING DIAGRAM:










1. CHECK HARNESS CONNECTOR BETWEEN TCM AND ECM.
- Turn ignition switch to OFF.
- Disconnect connectors from TCM and ECM.



- Measure resistance of harness connector between TCM and ECM.

Specified resistance (B68) No.16 - (B59) No.79: 1 Ohm or less




- Measure resistance of harness connector between TCM and body to make sure that circuit does not short.

Specified resistance (B68) No.16 - Body: 1 M Ohm, or more

2. CHECK INPUT SIGNAL FOR TCM.
- Connect connectors to TCM and ECM.
- Turn ignition switch to ON.



- Measure signal voltage between TCM connector terminal and body.

Specified voltage (B68) No.16 - Body: 1 Volt
