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
During normal driving the system is passive and the brakes work conventionally. Only under hard braking does the pump start to pulse, and you can feel vibrations in the brake pedal.
Matching
For this model we offer several pumps with different numbers. The number on the label decides, not the model name alone. The ABS pump is part of the safety system, so it is worth comparing the numbers carefully before buying. A mismatched version may not work with the car's sensors or wiring.
Symptoms of a faulty ABS pump
- the ABS warning light goes out and comes on by itself,
- the wheels lock under hard braking,
- the tester shows a control module or valve fault,
- traction control switches off.
Start by checking the fuse and connectors; replace the pump only when the wiring and sensors are in working order.
