A malfunctioning BCM will activate dashboard instrumentation cluster error and warning lights. These lights may flash off and on if the BCM is not able to read the sensors correctly.
Your vehicle performance may also be affected as the BCM communicates with other control modules in the vehicle. Parasitic drain is due to components in your vehicle continuing to run after the key is turned off.
Some parasitic drain is normal — your battery delivers enough energy to keep things like your clock, your radio presets and your security alarm operational. Sometimes, parasitic drain exceeds what is normal, and can cause car battery drain. In many cases, your BCM will alert you to issues with symptoms, warning lights or both. The key is to heed these warning signs, take prompt action and seek help.
Avoiding these warning signs or delaying taking action could cause further vehicle damage, or even a system-wide failure. BCM problems can also mask issues with other modules in your vehicle.

I don't even think you will have to carry out PATS programming this way. Help is free when you push them.
Fair enough. Things must have changed then. Only used to need as-built data if no comms with old unit, or if module had been flashed with wrong calibration file. All the spec's of the vehicle are in BCM from Tyre size to Alternator output all change able i guess is to update. Easy It did'n work. Replies: 8. Replies: 1. Last Post by Prostar. Replies: 4.
