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.

Signs of a faulty fuse box with module
- a fault warning light stays on after the engine starts,
- fuses keep blowing even after replacement,
- the central locking, windows or wipers work irregularly,
- the wipers or electric windows stop at random moments.
Before you buy a box, check the battery, fuses, earth connections and connectors - a damp wiring harness or a faulty relay causes similar symptoms.
