4T65EV Transmission

Signal missing

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 shift lock solenoid connector (control module side). Check for an open-circuit. 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.

Other information
- To check or replace the shift lock solenoid, see Solenoid back-up (reverse) inhibitor, replacing Solenoid Back-Up (Reverse) Inhibitor, Replacing.

Fault-tracing information




Information

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

Attempt New Test - Checking the P-shift lock solenoid

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

Intermittent fault
Check the control module for the gear selector and the solenoid connectors. Check for intermittent contact resistance according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Check the cable between the gear selector module (GSM) and the shift lock solenoid. Check for an intermittent open-circuit. See Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Remedy as necessary.

Information

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
