When Does This Fault Occur?
This issue typically arises when you either attempt to start the vehicle with a flat battery or jump-start the car.
Understanding the Fault:
When starting the vehicle with a flat battery, the Body Control Module (BCM) doesn’t get enough power, leading to data corruption. Consequently, the BCM cannot properly communicate with other modules, resulting in the vehicle’s immobilisation for security reasons.
Key Modules Affected:
- BCM (Body Control Module): Manages immobiliser, remote central locking, lights, wipers, and more.
- ECM (Engine Control Module): Controls engine functions including fuel, air, and ignition.
- IPC (Instrument Cluster): Houses the speedometer, rev counter, and warning lights.
- SDM (Airbag Module): Controls airbag deployment for safety.
Fixing the Problem:
To resolve this issue, genuine Tech 2 Vauxhall diagnostics are required. The BCM must be reset and reprogrammed to sync with the other security modules.
