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 control module receives signals from the wheel speed sensors and compares them. When one wheel slows down faster than the others, it controls the valves in the hydraulic block to prevent it from locking.
Matching
Compare number B30R 437A0 in full with the number on your pump. Different versions were fitted to the same models, so the number decides the fit, not the model and year alone. Module numbers are written with spaces or as one string. We give both forms to make the part easier to find.
Symptoms of a faulty ABS pump
- the ABS warning light is on,
- ABS stops working during braking,
- the control module does not communicate with the diagnostic tool,
- sometimes the ESP or traction control light comes on as well.
Inspect the control module connector: corrosion or burnt contacts cause symptoms similar to faulty electronics.
