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
One module contains two parts: the hydraulic block with valves and pump, and the electronics that control them. Both work together within fractions of a second, especially on slippery surfaces.
Matching
The number 20774272 also appears in another listing. Compare all the numbers with the label on your pump - we do not assume that listings are interchangeable. 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.
Questions and answers
| Is the part new? |
|---|
| The pump is used, but in working order. You will find its condition in the product features. |
| Do the brakes need bleeding after replacement? |
| Yes, once the brake system has been opened it must be bled. In many cars this is done with a diagnostic tool that activates the ABS valves. |
| Can I fit a pump from a different equipment version? |
| We do not assume so. Modules differ in functions (ABS, ESP, ASR) and software, so compare the numbers and the version of your car. |
