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 valves in the hydraulic block open and close many times per second, and the control module monitors their operation continuously. A failure of any of these parts turns on the ABS warning light.
Matching
We also offer other pumps for this model with different numbers. Choose by the number on the module, not by the model alone. 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,
- the system switches to emergency mode.
If the brake system has been opened, it must be bled after fitting, often using a diagnostic tool that controls the ABS valves.
