Hi, can anyone help?
L322 tdv8 2007, seems like a possible ignition switch fault. Various warnings came in the dash inc airbag hdc gearbox etc drove it and the engine cut out, I restarted it and drove on then the brake lights were coming on and off by themselves and the engine cut out again. It's now got no ignition lights and no communication with the engine ECU, other fault codes inc communication issues between most modules but it will no longer communicate at all. The battery voltage is good and it is currently hooked upto a battery support unit. Can anyone point me in the right direction to test the ignition switch without having to strip the dash out first? Many thanks.

Dash has to be stripped to access the switch, unfortunately

I was hoping for a miracle! If I knew where the switch outputs went I could test for a live but I cant find the wiring diagram for the ignition on technical date unfortunately. Cheers

UPDATE. All sorted, I pulled the ignition switch out stripped it and cleaned up the contacts with diamond contact cleaning blades. Started up and warning lights all clear.
