Hi

I have this zafira with the codes p0335,po340 which will clear but come back on starting the car u2103 has not returned. There is no rpm signal in the coolant module or dash [tach not working] but is in the other modules, I think there is a brake in the can line but do you know which wires they are I was looking for twisted wires but ther are none also do you know which order the can line goes to each ecu/node.

Hi Ray, if you go to DLC, pins 6 and 14 normally you can check can line integrity with ohms test, about 60 ohms and also scope the lines. HTH

Hi

Thanks have found fault with crank sensor this engine will run & start with the crank sensor disconnected fitted new sensor runs a treat now. the can line only seems to run the engine ecu, steering sensor, abs and transmission. Ray
