4T65EV Transmission






Signal too high

Checking the P-shift lock solenoid




- Ignition on
- Gear selector in position P
- Try moving the gear selector to another position without depressing the brake pedal. It should not be possible to move the gear selector
- Depress the brake pedal and try moving the gear selector to another position. It should now be possible to move the gear selector.

Was the function OK?

Yes - Intermittent fault

No - Checking the wiring and component

-------------------------------------------------

Checking the wiring and component
Check the cable between the gear selector module (GSM) and the solenoid connectors. Check for a short-circuit to supply voltage. See Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.

Hint: With a voltmeter connected to solenoid connector terminals #1 and #2 (gear selector control module side), the voltage should be 0 V when the brake pedal is not depressed and approximately Ubat when it is depressed. Replace the solenoid if the voltage is OK

Remedy as necessary.

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

Do you want to exit fault-tracing?

Yes - Exit Fault-Tracing

No - Attempt New Test

Intermittent fault
Check the cable between the control module for the gear selector and the shift lock solenoid. Check for an intermittent short-circuit to supply voltage according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Remedy as necessary.
