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 this part works
It is an electronic node of the body wiring: it receives signals from switches and sensors and then activates consumers such as lights, locks or ventilation. BSI (Boîtier de Servitude Intelligent) is the name of the comfort module used in PSA group cars and, in some models, in vehicles linked to that group.
When to replace the part
- the interior lighting does not switch off,
- nothing happens when settings are changed,
- door signalling works incorrectly,
- the battery drains overnight for no obvious reason.
It is worth reading the fault codes first, because many body faults come from switches or wiring rather than the module itself.
