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.

Fitment
Check the number 13 500 186 BS on your alternator. Versions of the same model could have different output and design, so the number decides, not the model. 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. If the belt is worn or loose, the replacement alternator may work worse than it should.
