    traction control failure & left brake light failure

    9-3 1.8i 54 plate
    hi went for a drive yesterday and left brake light failure came up on the display so I stopped and checked and it is working fine half hour later brake and abs warning lights come on along with traction control failure on the display and the speedo & rev counter stopped working so I stopped turned the ignition off and attempted to restart and the engine didn't even turn over, I left it for 15 mins and it started but messages and lights have been coming back intermittently

    tech 2
    cim p bus
    left brake light circuit open

    anyone know of anything that could cause this or have a copy of WIS they want to sell?
    cheers

    It could be a sign of a failing alternator - they often cause all sorts of electrical gremlins. Get the alternator's output checked.

    Replaced the alternator and faults stayed (other than low voltage) and it got to the point that the engine light came on aswell and had no power (had to stop on m1) so called AA his tool said no faults, tech2 said 19 faults all bus related all on p bus
    So on tech2 I removed the CIM then added it reprogramming the keys in the process
    in 3 days no faults so far so alls good
    might be worth a try for others if they have traction control failure
    My CIM is only 4 years old after having airbag failure which saab replaced the CIM for
