UCH reports immo info correct and ecu not locked.
Ign and earths correct at ecu but management relay not being pulled in on plug B pin k1.
CAN signal is not the cleanest ive seen but not the worst either. Not sure if this ecu needs the correct can to power up and talk or if I have a faulty ecu.
So I found a 2nd hand ecu, expecting it to power up and say immo signal incorrect, but it behaves the same way ie no coms and not switching management relay.
Using the snapon scope powering from its own battery the CAN at breakout box and ecu looks correct untill the 12v lead is used to power the modis, then the two traces rise by 2 volts and become distorted?? same if the dl16 is used to power the modis?
Sorry for length, can anyone confirm if these ecu s Siemens sid301, will or will not power up with a missing or poor immo signal on the CAN?
