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
One module contains two parts: the hydraulic block with valves and pump, and the electronics that control them. Both work together within fractions of a second, especially on slippery surfaces.
Matching
The number 20774272 also appears in another listing. Compare all the numbers with the label on your pump - we do not assume that listings are interchangeable. Modules differ, among other things, in the layout of the brake line ports and the connector. Always compare the numbers and the appearance of your pump with the unit in the listing.
Symptoms of a faulty ABS pump
- the ABS warning light goes out and comes on by itself,
- the wheels lock under hard braking,
- the tester shows a control module or valve fault,
- traction control switches off.
If the brake system has been opened, it must be bled after fitting, often using a diagnostic tool that controls the ABS valves.
