Cant get car out of Park

OK Dave gocha I'll buzz it all out tomorrow. I checked power on one of the spare sockets in the CEM and thats live and no other problems. So is this possibly a CEM fault?

Another question puzzling me is this 'inerlock solenoid' on the automatic gear shift. This always disengages when you put your foot on the brake.This obviously isnt working atm but I cant see this solenoid shown on any diagram?

Im not sure of its 'official name'. There are 4 pins on the brake light switch but only 2 are used so where does this solenoid get its voltage from?

Its a bit worrying as reading up this solenoid is also controlled by the CEM so this might be pointing at a very expensive failure if the CEM has scrammed?

Page 119 is the diagram you want, "Shift Lock"

The power for the shift lock comes from the Gearbox Module which is powered by Fuse 21 in the CEM bank

But check the brake switch wiring first...
