Hi

I have this corsa 54 plate with a 1.2 16v with the bosch 1.5.5 ecu. I am using tech 2.
I can’t get coms with the ecu or immobilizer. The engine mil light flashes tell me the ecu is immobilized. I can get comms with the bcm and abs. The can wires seem to go from the bcm to the abs to engine ecu.
I have tested the can leads including put a load on them, I have tried by passing the abs by joining the 2 can leads together, I have tried a second ecu. The ecu is live as the idle control works and I have 5 volts on the system, I also have some live data from the ecu viva the bcm like engine rpm when I crank the engine and engine temp. ray
