A faulty transmission control module (TCM) most often causes limp mode with the gearbox stuck in one gear, harsh jolts when you select D or R, erratic gear changes, flashing PRND letters and a gearbox or engine warning light. However, the same symptoms are often caused by a low gearbox oil level, a weak battery, a poor earth or a faulty sensor. To test a transmission control module, start by checking the battery and reading the fault codes with a diagnostic tool that can talk to the gearbox control unit, then check the power supply, the connector, the oil and the live data. Below we explain the symptoms, the diagnostic steps and what the most common fault codes mean.

- the dashboard shows the door as open,
- the door is hard to close or does not open from inside,
- the door does not unlock with the remote.
The lock in the central locking system
Door locks are exposed to moisture, frost and frequent use, so the latch mechanism and the actuator wear over time. That is why a single door often stops responding to central locking while the others still work.
Matching by number
If several doors stop working at once, the cause is more likely the central locking control, a fuse or the wiring between door and body than the lock itself. Before replacing the lock, check that the rods to the handle are not seized and that power reaches the connector. A broken wire in the door loom gives similar symptoms.
Frequently asked questions

| What should I check when fitting? |
| Check the connector, the wiring in the door and the rods to the inner and outer handle. |
| Can I ask about fitment before buying? |
| Yes. Send us the number or a photo of your lock and we will check it for you. |
