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 return pump motor runs only when ABS is active. The rest of the time it puts no load on the electrical system, but together with the valves it is one of the parts most exposed to wear.
Matching
For this model we offer several pumps with different numbers. The number on the label decides, not the model name 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
- ABS does not react to wheel slip,
- ESP or ASR does not switch on,
- power supply faults in the diagnostic memory,
- signs of corrosion are visible on the connector.
Check the level and condition of the brake fluid; old or contaminated fluid accelerates wear of the valves in the hydraulic unit.
