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.

Compare the numbers with the original pump in your car, and if any of them differs, write to us before buying.
Symptoms of a faulty ABS pump or control unit
- the ABS activates for no reason during normal braking,
- brake fluid leaks from the hydraulic block, which requires immediate action,
- the ABS warning light comes on together with the stability control warning light,
- the ABS switches itself off shortly after the engine is started.
It is worth reading the fault codes and checking the sensor wiring before replacement. Fitting and bleeding the brake system are usually carried out by a garage with the right equipment.
Questions and answers
| Which car model does this pump fit? |
|---|
| The listing does not state a model or year, so confirm compatibility with the number from the original pump in your car, or send us a photo of it. |
| Are the make and model of the car enough to choose the part? |
| No. A single model comes with different versions of the module, depending on the engine, year of manufacture and drivetrain. The most reliable reference is the number on the original pump. |
| Do the brakes need bleeding after replacing the module? |
| If the brake lines are disconnected during fitting, the system must be bled. The fault codes in the control unit usually need to be cleared as well. |
| What condition is this ABS module in? |
| It is an original recycled part in good condition, checked by us. Warranty details are in the product features table. |
