Factory Back-up Sensor Test/ Fix???
So my factory back-up sensors are not working and I was looking for some troubleshooting tips. I had a scanner hooked up not too long ago and did not receive any codes relating to it. The dash light to turn the sensor on and off lights up and turns off fine. Does anyone have/ know of the test procedure to check these?

Got to sneak out real quick to check this out. Didn't hear any clicking but led me to another question, the back up sensor button next to the 4x4 selector stayed lit ("OFF"). I tried to turn the light off which should turn the sensors on but it would not let me. Should the light stay on or should I be able to turn it on and off in that situation?

You can only turn the light off if your not in reverse. I have one bad sensor and my off light comes on as soon as I put in reverse and will not go off until I push the button to turn it off. I'd try and find a quite place and listen to your sensors again, I'm sure you'll hear it with your ear on the sensor.

I went through this with my Excursion a few years ago. Like th67ss said - you can only turn the light off when you are not in reverse. When you put it in reverse the system does a quick systems check, if it doesn't receive the signal from the sensor it trips the code, disables the system and turns the light in the button on. Now, when I had 2 bad sensors Auto Enginuity did pick up the codes....what scanner are you using?

Here are the possible codes that would point to the system malfunction:
C1699 Rear Outer Left Sensor Short to Battery - PAM
C1700 Rear Outer Left Sensor Circuit Failure - PAM
C1701 Rear Outer Left Sensor Fault - PAM
C1702 Rear Outer Right Sensor Short to Battery - PAM
C1703 Rear Outer Right Sensor Circuit Failure - PAM
C1704 Rear Outer Right Sensor Fault - PAM
C1705 Rear Inner Left Sensor Short to Battery - PAM
C1706 Rear Inner Left Sensor Circuit Failure - PAM
C1707 Rear Inner Left Sensor Fault - PAM
C1708 Rear Inner Right Sensor Short to Battery - PAM
C1709 Rear Inner Right Sensor Circuit Failure - PAM
C1710 Rear Inner Right Sensor Fault - PAM
So basically there are 3 possibilities for each sensor.

Just noticed this, I tried to do the test to listen to the sensors. I key on the truck, and turned the back up sensors on (light off on button), and as soon as I put it in reverse the light comes back on (back-up sensors off). Does this help point me in any direction. I just had a basic universal scanner when the right side glow plug module went out. So that one didn't pick up any other codes ....
