Anyone know how the immobilizer works on a p80? (more exactly a 98 C70) Mine is malfunctioning, and I would like to get it going.
So far, I get that the ECU, immobilizer module (under steering) and key immobiliser ring all communicate with each other to decide whether to allow the car to start. I have checked and cleaned the connection to the immobiliser ring, to the immobiliser module, and the ECU is obviously plugged in, but the immobiliser is still activating! I have also replaced the immobiliser ring, but no help. Are there any other parts that talk to the immobiliser?
As some background, I replaced the dash in this car, and straight afterwards it refused to start. At first, I suspected something being left unplugged, but I didnt touch the immobilizer ring. I did, however, find that the car starts fine with a custom ECU that doesnt have immobiliser functionality - so I know it is definitely that.
Any help is appreciated, as I would rather fix this than solder and flash the ECU.
