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.

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 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 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
- the ABS warning light is on,
- ABS stops working during braking,
- the control module does not communicate with the diagnostic tool,
- sometimes the ESP or traction control light comes on as well.
Before you buy a pump, check the fuse, power supply, earth and wheel speed sensors - a damaged wiring loom or sensor can cause similar symptoms.
