    Why won't the reversing alert work in my 2015 Holden Colorado 7?

    Why won't my reversing alert work in my 2015 Holden Colorado 7? I have backed into a concrete barrier and pushed one sensor out.

    Okay, first question: Did the sensor damage happen before or after the failure of the alert? If it’s the former, it’s a fair bet the crunch has broken the sensor in question and led to the whole inter-linked system failing.

    If the problem happened before the bump (and caused the knock because it didn’t warn you of the looming barrier) then you need to investigate further. An auto electrician should be able to test the system and its circuits and tell you what the cause of the problem is. It could be anything from the wiring to a blown fuse to the sensors themselves having failed. Living on the very edge of the vehicle, these sensors have a pretty hard life with every tap and bump to the bumper potentially damaging them or their circuitry.
