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.
1) Turn ignition switch to OFF.
2) Disconnect connectors from TCM and ECM.





3) Measure resistance of harness connector between TCM and ECM.

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





4) 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 Ohms, or more

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





3) Measure signal voltage between TCM connector terminal and body.

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