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 an ABS pump with control module works
In cars with ESP or traction control, the same module can also build up pressure at a selected wheel to stabilise the vehicle. The range of functions depends on the equipment of the specific car.
Matching
Compare number 43 7A0 B603437A0 in full with the number on your pump. Different versions were fitted to the same models, so the number decides the fit, not the model alone. Modules differ, among other things, in the layout of the brake line ports and the connector. Always compare the numbers and the appearance of your pump with the unit in the listing.
Symptoms of a faulty ABS pump
- ABS does not react to wheel slip,
- ESP or ASR does not switch on,
- power supply faults in the diagnostic memory,
- signs of corrosion are visible on the connector.
Check the level and condition of the brake fluid; old or contaminated fluid accelerates wear of the valves in the hydraulic unit.
