2013 Nissan Pathfinder glow plug relay

Post by Twins »

Fault code for glow plug relay P0380
replaced glow plugs and relay (same fault)
checked wiring from ecu to relay (all ok)
It has a pwm signal to activate the relay & a return signal to the ecu. When i checked it with a good known i have found a problem with the return signal but don't know what is causing it. I have tried a 2nd hand ecu from donor vehicle but get the same signal.
