Mk1 Focus - Frying PATS Transceiver
Discussion
Hi Folks,
Engine etc actually in a MEV Rocket, will duplicate this post in kit cars, but hoping you ford chaps can belp out.
I put my car in to get a wheel bearing done and they phoned to say it wouldn't start, immobiliser LED flashing rapidly. Took spare key down, same thing. Turned out the ring that goes round the ignition barrel (PATS transceiver i believe it's actually called) was shot so they replaced, car started.... only thing is the transceiver was heating up and when it was turned off and back on, back to square 1, rapidly flashing LED.
Auto spark (Porsche garage!) has been eliminating things and it appears earch is ok, the feed from the transceiver to ECU and back are continuous and even compared voltages in the MEV vs. a Ford Focus and all appears to tie up (9.9v going back to the transceiver).
Thought perhaps it was an ECU fault and i happen to have a spare (beauty of a kit car with parts!) so switched it out and exact same thing happened.
I've only had the car 2 weeks (1 of which its been in garage for this issue!) and i didn't build it so not even had a chance to really get under the skin of it. Old owner (also built it) has been really helpful but drawing a blank plus he's 300 miles away!.
Any input gratefully received.
