I made an account just to post the fix for this, couldn't find it anywhere.... Your mileage may vary but this is what worked for me. After having my alarm go off continuously with the hood ajar message I unplugged the hood latch sensor to fix the issue but in doing so I lost my factory remote start, not an big deal during the summer but now that its 20 degrees out its an issue. I dislike spending $100-$200 to replace a part that works fine because the $1 electrical switch integrated into it broke. The BCM seems to use logic on that pin other than high/low so the fix isn't as simple as twist the wires together. I ended up cutting the sensor/switch pigtail and wiring in a 10k ohm potentiometer and turning it till it worked. For my truck that was ~2100 ohms. The truck harness only utilizes two wires of the three pin connector and one of them is a ground. Solder in the 2100 ohm resistor in between the red and black wires as shown attached (don't forget to put the shrink tube on before) plug it in and the hood switch will be bypassed in the "hood closed" position. keep in mind that you can now remote start with the hood open and peoples hands in there. Use at your own risk. 2015 GMC Sierra 1500 SLE 4x4 5.3L
