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
ABS does not shorten the braking distance in all conditions, but it lets you steer the car under hard braking. The pump with control module is the heart of this mechanism.
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 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.
The brake system is crucial for safety - after replacement, bleed the brakes and have the ABS checked in a workshop.
