In the last week or so, my alarm has gone off several times for no reason. usually LATE at night, but once after it sitting for an hour. There is a few posts about it, though not really any solid solutions. Hoping someone here has bypassed the sensor by jumping the connector and if that held up. The connection looks great, no corrosion or frayed wires. Also have had the Hood Ajar warning come up after getting a car wash, and once after a heavy rain.

This happened to me. Unplugged it for a while and then bought a new hood latch setup with a sensor from rockauto for $45ish shipped.

how long have you had that new assembly in? no issues since?
Hey so sorry it didn't notify me of your reply! Nope, no issues! Been about 3 months now. With my old latch I noticed it would be particularly bad on cold mornings and when going over bumps which made me realize it had to be the switch sensor in the latch. Looks like you might have the same issue. The one I got was from Dorman and has a lifetime warranty if the switch goes bad again. Took about 5 minutes to swap it out. Highly recommend!

if I remember correctly. the hood pin is a "normally closed" negative trigger. that means when ever the wire sees a ground signal, it will think the hood is closed. you should just have to unplug it and ground the Blue/Orange wire to simulate the sensor in the latch being closed. I would temporarily do this and see if the problem goes away. if it does then your problem is the switch in the latch. if it does happen again, you either have a wiring problem or something is going wrong with the BCM (the switch failing is by far the most likely problem)

@brianlovelace & @1LoudST thanks for the great input!! i almost just wanna get a new latch at this point. Tho i may just jump the connection and see if it works, just to verify its the switch and not the harness. Again, thank you so much!!
P.S sorry for the late ass response haha

The switch is intergrated with the hood latch. If it has failed then you will need to replace it.

The two small pin connectors inside the plug, need to be bent slightly out of line, so when the plug is pushed on the connection is tighter, it cured the same problem I was having.
