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.

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,

Before you buy a pump, check the fuse, power supply, earth and wheel speed sensors - a damaged wiring loom or sensor can cause similar symptoms.
