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
The number 3A0907379 also appears in another listing. Compare all the numbers with the label on your pump - we do not assume that listings are interchangeable. The fit is decided first of all by the part number, and only then by the model and year, because different modules were used within one model.
Symptoms of a faulty ABS pump
- valve fault codes appear,
- the ABS works unevenly,
- the warning light stays on even after a sensor replacement,
- the module stops responding after moisture gets in.
Check the level and condition of the brake fluid; old or contaminated fluid accelerates wear of the valves in the hydraulic unit.
Questions and answers
| What condition is this part in? |
|---|
| It is a used, working part in good condition. The condition is also given in the product features. |
| Can I drive with the ABS warning light on? |
| Usually the car still brakes without ABS assistance, but the wheels can lock and ESP will not work. The repair should be done as soon as possible. |
| 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. |
