Short-Circuit To Ground

Checking Solenoid S2
- Ignition ON.
- Move gear selector to position P.
- Activate solenoid S2. Read off the solenoid status. The status should alternate between OFF/ON.
- Does the status alternate between OFF/ON?

Yes:
- Proceed to: Intermittent Fault section below.

No:
- Proceed to: Checking Signal Wiring Resistance To Ground In The Transmission section below.





Checking Signal Wiring Resistance To Ground In The Transmission
- Ignition OFF.
- Raise the car to access the transmission.
- Carefully clean round connector D.
- Disconnect transmission connector D.
- Connect an ohmmeter between transmission connector D, terminal 2 (transmission side) and ground.
- The ohmmeter should read 12-18 Ohms.

If reading is OK:
- Proceed to: Checking For A Short-circuit section below.

If reading is incorrect:
- Proceed to: Checking Solenoid S2 section below.





Checking For A Short-circuit
- Check cable between transmission connector D terminal 2 and transmission control module (TCM) # 31 for a short-circuit to ground.
- Proceed to: Verification section below.





Checking Solenoid S2
- Ignition OFF.
- Open the control system.
- Disconnect solenoid S2.
- Use an ohmmeter to measure between the pin on solenoid S2 and the transmission housing.
- The ohmmeter should read 12-18 Ohms.

If reading is OK:
- Proceed to: Checking For A Short-circuit section below.

If reading is incorrect:
- Proceed to: Replacing Component section below.





Checking For A Short-circuit
- Check cable between solenoid S2 and transmission connector D terminal 2 for a short circuit to ground.
- Proceed to: Verification section below.





Replacing Component
- Ignition OFF.
- Try a new solenoid S2.
- Proceed to: Verification section below.





Verification
- After repairs have been completed they must be verified as follows to ensure the fault has been eliminated:

- Ignition ON.
- Move gear selector to position P.

- Activate solenoid S2. Read off the solenoid status. The status should alternate between OFF/ON.
- Does the status alternate between OFF/ON?

Yes:
- Fault corrected.

No:
- Proceed to: Fault-tracing Information section below.

Fault-tracing Information
The verification result shows that the fault persists.

- Do you want to exit fault-tracing?

Yes:
- Fault not corrected.

No:
- Proceed to: Checking Solenoid S2 section above.





Intermittent Fault
- Check cable between solenoid S2 in transmission and transmission control module # 31 for an intermittent short-circuit to ground.
- Proceed to: Fault-tracing Information section below.

Fault-tracing Information
For intermittent faults fault-tracing is not followed by a verification because the fault is not present at this moment.

- Do you want to repeat fault-tracing?

Yes:
- Proceed to: Checking Solenoid S2 section above.

No:
- Operation done.
