04RSD Member 78 Member For: 17y 6m 19d Posted 19/01/12 09:20 PM Share Posted 19/01/12 09:20 PM hey guys I hust got myself a written off 5 speed ba xr6 for a donor vehicle.its been sitting with a flat battery for a good 8 months, I put a new battery in but no luck.my radio is showing CODE with ign on ( as soon as you turn ign on it should talk to bcm and power up )there is no crank, a few of the dash lights drop out as normal on crank but the little hand with the key and the red (!) flash up,im guessing dead bcm but im just guessing.I have a snap-on ETHOS scan tool but its pretty much useless for anything bigger than resetting seatbelt and airbag codes.any help would be great.I want to have a quick drive to make sure sure everything works ok Link to comment Share on other sites More sharing options...

Disconnect and connect everything just to make sure its all good.Make sure you get it working on that car before pulling stuff out. Otherwise you will spend a lot of time chasing your tail.

Not the other way around. If its lost code then that would explain why it won't start. Edited 20/01/12 03:39 AM by matt036 Link to comment Share on other sites More sharing options...

My money is the ICC has been dislodged and this is causing the code issue. The security functions are written in flash memory into the BEM, the settings cant be lost due too a flat battery.Look for obvious damage and work backwards from there.OP are you 110% sure you've been given the correct keys for the car? no damage too the ignition barrel receiver for the security system? No damage too the PCM connectors? Link to comment Share on other sites More sharing options...
