Ranbie Posted June 13, 2021 Report Share Posted June 13, 2021 Evening, I'm trying to fault find an AEM COP on my Link G4+ for a B18c. The issues I'm having are; -No timing light pulses while cranking. -A flat 4.3v trigger scope event. -No RPM signal. What I've checked; -Coil Test. (all work fine with timing light) -Confirmed all pins on sensor side are correct. -All pins on ECU side are as per Adamw's Illustration from another topic. I have consolidated every reference that I've been able to find on these forums to help me but I'm still unable to get a normal signal on the scope. Will continue to look for anything out of the ordinary but would appreciate some help! Quote Link to comment Share on other sites More sharing options...
