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.

Numbers to compare
The numbers as written on the labels and as a single string, the way catalogues list them:
- 3451 6778236 01 (catalogue format: 3451677823601), BMW number of the ABS pump (hydraulic part),
- 3452 6778237 01 (catalogue format: 3452677823701), BMW control unit number.
The full numbers matter, including their endings. If in doubt, send us a photo of your pump.
Symptoms of a faulty ABS pump or control unit
- the ABS stops working, although basic braking usually remains functional,
- valve or pump motor faults are stored in the control unit memory,
- the ABS activates for no reason during normal braking,
- the ABS warning light comes on together with the stability control warning light.
It is worth reading the fault codes and checking the sensor wiring before replacement. Fitting and bleeding the brake system are usually carried out by a garage with the right equipment.
