Vehicle came in with a hood open light randomly also has a service stabilitrak and service traction control at same time. This was approximately 6 months ago we replaced bcm and hood latch assembly and all was good. Customer has returned now with similar problem KOEO Stabilitrcak light and service traction control light on. When vehicle is running all is normal until use turn signals, or turn headlights on, or hit brakes then the hood open light comes on instrument panel display. Shut them off goes back to normal. I have replaced BCM again after cleaning all grounds and also observing the PID data it does change as soon as hood open light comes on saying hood open signal but also has a hood ajar fault at that time and goes back to correct readings when everything is off. I have also checked tail light junction block on rear of vehicle and for chaffed wires by bcm and by fuse block and junction block on end of dash and the junction block by brake pedal.......frustrating thanks frustrated technician!
