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 return pump motor runs only when ABS is active. The rest of the time it puts no load on the electrical system, but together with the valves it is one of the parts most exposed to wear.
Matching
For this model we offer several pumps with different numbers. The number on the label decides, not the model name alone. The brake system is critical for safety, so fitting is best left to a workshop that will bleed the brakes and check ABS operation.
Symptoms of a faulty ABS pump
- the ABS warning light is on,
- ABS stops working during braking,
- the control module does not communicate with the diagnostic tool,
- sometimes the ESP or traction control light comes on as well.
Compare all the numbers with the label on your pump, because the same car model may have had several versions.
