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
The module is connected by brake lines to the master cylinder and to the wheel circuits. That is why cleanliness must be maintained during replacement and the system must be bled thoroughly.
Matching
The number 9496439 also appears in another listing. Compare all the numbers with the label on your pump - we do not assume that listings are interchangeable. After replacement the module may need coding or adaptation to the car. Check this for your model before ordering the part.
Symptoms of a faulty ABS pump
- the ABS warning light comes on once the car has warmed up,
- the brake pedal vibrates for no reason,
- no communication with the module over the CAN bus,
