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 electronics store fault codes that can be read with a diagnostic tool. This makes it easier to determine whether the sensors, the wiring or the hydraulic unit itself is to blame.
Matching
For this model we offer several pumps with different numbers. The number on the label decides, not the model name alone. The brake system is critical for safety, so fitting is best left to a workshop that will bleed the brakes and check ABS operation.
Symptoms of a faulty ABS pump
- the ABS and brake warning lights do not go out after switching on the ignition,
- no wheel speed reading,
- the car reports sensor faults even though the sensors work,
- the module overheats or resets.
Start by checking the fuse and connectors; replace the pump only when the wiring and sensors are in working order.
