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
During normal driving the system is passive and the brakes work conventionally. Only under hard braking does the pump start to pulse, and you can feel vibrations in the brake pedal.
Matching
We also offer other pumps for this model with different numbers. Choose by the number on the module, not by the model alone. Car versions differ in, among other things, ESP, brake type and engine. Compare the numbers with your pump or with the vehicle documents.
Symptoms of a faulty ABS pump

Before buying, make sure the cause is not the power supply or the wiring loom, and only then replace the module.
