TROUBLE CODE 24
DUTY SOLENOID C

Diagnosis
Output signal circuit of Duty Solenoid C is open or shorted.

Trouble Symptom
Excessive "braking" in tight corners.











1. Check harness and connectors between Transmission Control Module (TCM) and Duty Solenoid C.
a. Turn Ignition Switch to "OFF".
b. Disconnect connectors from TCM and Transmission.





c. Measure resistance of harness connector between TCM and Transmission.
Connector & Terminal / Specified Resistance:
(B55) No. 3 - (B11) No. 11 / 1 Ohm, or less.





d. Measure resistance of harness connector between TCM and body to make sure that circuit does not short.
Connector & Terminal / Specified Resistance:
(B55) No. 3 - Body / 1 M-Ohm, or more.

2. Check Duty Solenoid C's Ground Line.





Measure resistance between Transmission connector receptacle and Transmission case.
Connector & Terminal / Specified Resistance:
(T4) No. 4 - Transmission / 1 Ohm, or less.

3. Check Duty Solenoid C.





Measure resistance between Transmission connector receptacle's terminals.
Connector & Terminal / Specified Resistance:
(T4) No. 11 - No. 4 / 9 - 17 Ohms.
