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 lock in the central locking system
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.
How to match this lock
Compare number 90503996AM in full with the label on your lock. The same model was fitted with different lock versions, so the number decides, not the model name alone. 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.
