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
In cars with ESP or traction control, the same module can also build up pressure at a selected wheel to stabilise the vehicle. The range of functions depends on the equipment of the specific car.
Matching
The number 9157654B 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 pump motor does not start,
- an unusual noise can be heard when braking,
- brake fluid leaks from the hydraulic unit,
- the brake pedal is hard or sinks.
It is worth reading the fault codes with a diagnostic tool first, because some ABS faults come from wheel sensors or wiring, not from the hydraulic unit itself.
