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.

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.
The lock in the central locking system
The lock holds the door latch closed and has an electric actuator that locks and unlocks it on command from the central locking system, so the remote or the button in the cabin operates all doors at once.
Signs of a faulty lock
- the door can only be opened by hand,
- the lock works loudly or with resistance,
- the door stays unlocked after locking the car,
- the lock does not hold the door in the latch.
