My Vauxhall Corsa D car battery went flat, now the car won’t start, why?

This problem only occurs with the Corsa D model (2006-2014), mostly on cars up to 2009.

The flat battery means the cars BCM (Body Control Module) has insufficient power to work properly, causing it to lose its coding. Now the car thinks this is an unmatched part i.e. a security risk, thus immobilising itself.

A tell tale sign is the picture of the car with the spanner through it on the instrument display.

Fault codes this generates with diagnostic tools are….

P1632 – Wrong transponder key.
P1678 – ECM identification failed
P1679 – Wrong environment identifier received BCM
B3114 – Remote key not synchronised
B3925 – Wrong environment identifier received IPC
B3929 – Wrong environment identifier received SDM
B3977 – Wrong environment identifier received ECM.
The solution is to re-program the BCM with the cars security code (we can extract this from the car easily) and then re-match the BCM, ECM (engine control module), IPC (instrument panel cluster) and SDM (sensing diagnostic module – airbag).
