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
The control module receives signals from the wheel speed sensors and compares them. When one wheel slows down faster than the others, it controls the valves in the hydraulic block to prevent it from locking.
Matching
For this model we offer several pumps with different numbers. The number on the label decides, not the model name alone. Car versions differ in, among other things, ESP, brake type and engine. Compare the numbers with your pump or with the vehicle documents.
Symptoms of a faulty ABS pump
- the ABS and brake warning lights do not go out after switching on the ignition,
- no wheel speed reading,
- the car reports sensor faults even though the sensors work,
- the module overheats or resets.
Inspect the control module connector: corrosion or burnt contacts cause symptoms similar to faulty electronics.
