Shift Lock Solenoid, Checking
Special tools, testers and auxiliary items required
- Multimeter.
- Wiring diagram.
Test requirements
- Fuse S13 OK.
- Brake Light Switch F OK.
- The ignition switched off.
Test procedure
- Perform a preliminary check to verify the customers complaint. Refer to → Preliminary Check .
- Disconnect the Shift Lock Solenoid N110 electrical harness connector - 1 - by releasing the catches - arrow A - and pulling away from the solenoid - arrow B -
Checking internal resistance
- Using a Multimeter , check the Shift Lock Solenoid N110 terminals 1 and 2 - B - for resistance.
Specified value: 21.3 to 23.3 Ω.
If the specified value is not obtained:
- Replace the Shift Lock Solenoid N110. Refer to the appropriate service information .
If the specification is obtained:
Checking voltage supply
- Using a Multimeter , check the Shift Lock Solenoid N110 terminal T2l/1 to Ground (GND) for voltage.

|---|---|
| 1 | Engine Ground (GND) |
- Switch the ignition on.
- Depress the brake pedal.
Specified value: battery voltage.
- Release the brake pedal.
Specified value: 0V.
- Switch the ignition off.
If the specified value was not obtained:
- Check the wiring connection from the Transmission Control Module (TCM) J217 electrical connector T20e/5 terminal to the Shift Lock Solenoid N110 electrical harness connector terminal T2l/1 to for an open circuit or a short to Battery positive (+).

If the specified value was not obtained:
- Check the electrical harness connector for damage, corrosion, loose or broken terminals.
- If necessary, repair the wiring connection.
If the specified value was obtained:
Check Ground (GND) activation
- Using a Multimeter , check the Shift Lock Solenoid N110 electrical harness connector terminal T2l/2 to Battery (+) for voltage.
| Shift Lock Solenoid N110 electrical harness connector terminal T2l | Measure to |
|---|---|
| 2 | Battery positive (+) |
- Switch the ignition on.
Specified value: battery voltage.
- Switch the ignition off.
If the specified value was not obtained:
- Check the wiring connection from the Shift Lock Solenoid N110 electrical harness connector terminal T2l/2 to ground connection 8 (in the main wiring harness) for an open circuit or a short to Battery positive (+).
- Check the electrical harness connector for damage, corrosion, loose or broken terminals.
- If necessary, repair the wiring connection.
If the specified value was obtained:
Checking wiring
If the manufacturers test box is being used, perform the following step.
- Install the test box VAG1598/31. Refer to 24 - FUEL INJECTION SYSTEM .
If the manufacturers test box is not being used, perform the following step.
- Remove the Transmission Control Module (TCM) J217. Refer to → Transmission Control Module, Replacing .
- Using a Multimeter , check the Shift Lock Solenoid N110 terminal T2am1 to the Brake Light Switch F electrical connector terminal 4
- Using a Multimeter , check the Shift Lock Solenoid electrical connector terminals T2am2 to Transmission Control Module (TCM) J217 electrical connector terminal 7 for an open circuit.
| Shift Lock Solenoid N110 electrical harness connector T2l terminal | Measure to |
|---|---|
| 1 | Transmission Control Module (TCM) J217 terminal T20e5 |
| 2 | Ground Connection 8 (in the main wiring harness) |
Specified value: 1.5 Ω max.
If the specification is not obtained:
- Check the wiring for a short circuit to each other, to Battery positive (+), Ground (GND) or an open circuit.
- Check the electrical harness connector for damage, corrosion, loose or broken terminals.
- If necessary, repair the wiring connection.
- Erase the DTC memory. Refer to → Diagnostic Mode 04 - Reset/Delete Diagnostic Data .
- Perform a road test to verify repair.
If the DTC does not return:
Repair complete, Generate readiness code. Refer to → Readiness Code .
- End diagnosis.
If the DTC does return and no malfunction is detected in the wiring and the voltage supply was OK:
- Replace the Transmission Control Module (TCM) J217. Refer to → Transmission Control Module, Replacing .
- Assembly is performed in the reverse of the removal.
After the repair work, the following work steps must be performed in the following sequence:
- Check the DTC memory.
- If necessary, erase the DTC memory. Refer to Diagnostic Mode 04 - Reset/Delete Diagnostic Data .
- If the DTC memory was erased, generate readiness code. Refer to Readiness Code .
