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. The fit is decided first of all by the part number, and only then by the model and year, because different modules were used within one model.
Symptoms of a faulty ABS pump
- the ABS warning light comes on straight after starting the engine,
- the diagnostic tester cannot connect to the module,
- the speedometer shows incorrect readings,
- the system works only intermittently.
Remember that after replacement the module may need coding or adaptation - check this for your model.
