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
The number A 172 431 37 12 also appears in another listing. Compare all the numbers with the label on your pump - we do not assume that listings are interchangeable. After replacement the module may need coding or adaptation to the car. Check this for your model before ordering the part.
Symptoms of a faulty ABS pump
- a return pump fault is stored in the control module memory,
- ABS activates unnecessarily on a dry road surface,
- the ABS and ESP warning lights come on together,
- a pump supply voltage fault appears.
Compare all the numbers with the label on your pump, because the same car model may have had several versions.
