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.

How to match this lock
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 ordering, compare the shape, connector and mounting points with the lock fitted in your car. Locks with similar numbers can differ in design.
Typical faults
- the lock jams when closing,
- the door is hard to close or does not open from inside,
- the door stays unlocked after locking the car,
- central locking does not lock this door.
What the lock does
The lock works together with the outer handle, the inner handle and the lock button, connected by rods or cables. The central locking module only sends the signal; the movement is made by the actuator in the lock.
