Hey Everyone, So for 90,000 miles my reverse sensing system worked like a dream, now suddenly it shuts itself off intermittently. No codes stored in the system, any ideas?

 

Ok, i'm convinced its one of the sensors thats going bad, any way to determine which one?

 

Hmm not sure how this will work...but just thinking off the top of my head. This would require two people and a length of board, pipe, etc.

Put your friend in the drivers seat, brake on, truck in reverse. You climb in the bed with the tailgate up, and with said length of board (2x4 we'll say) place it directly in front of each sensor maybe 2-4" away so that the other sensors cannot detect said board. With your body in the bed, the other sensors should not detect you, thus you should be able to move from sensor to sensor and hopefully determine which might be bad.

Again, this is my completely uneducated/backyard/"here watch this" solution to what could be your problem. I have NO idea if it'll work, but it's the only thing I can conjure up at the moment.

 

Well the problem is that the system shuts off on itself before i'd get a chance to try that. I get in the truck, start it up, put it in reverse and the OFF light comes on for the reverse sensing. I guess i'm down to swapping them out one at a time......

 

Try just putting a piece of tape over one sensor at a time and see if it stays long enough to check. I've also heard there's a connector in the sensor wiring somewhere around the transmission that has a tendency to corrode up so you might want to check that out.

Good luck

 

You could go to the dealer and have them check the sensors with thier IDS analyser and know which one is faulted. I would clean them, make sure they are flush with the bumper, and remove the connectors on the rear, clean with some deoxit and reseat them all first. If the problem persists its time to let the pros tell you what is wrong.
