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.

Matching by numbers
Compare the full number 0986043101 with the number on your alternator. Different versions were fitted to the same models, so the number decides, not the model alone. Versions differ in current output and mounting, among other things, so even similar numbers do not always mean the same alternator.
How an alternator works
Inside the alternator the alternating current is rectified and the regulator controls the charging voltage. This keeps the battery charged and gives the electrical consumers a stable supply. After fitting, it is worth checking the charging voltage with the engine running.
When the alternator needs replacing
- the charging voltage is too low or too high,
- the ribbed belt squeals,
- the lights are weak at idle,
- the on-board computer reports a charging system fault.
Before buying an alternator, check the battery, the drive belt and the connectors - they can cause similar symptoms.
