Recently I noticed my back up camera was not working. I checked all my wiring at the head unit/stereo and the driver side reverse light that the trigger wire is connected to. All the wiring was good. Upon investigating the camera I noticed my reverse lights are not working at all, which explains why the camera is also probably not working. I've looked at se wire diagrams but can't seem to find any that point out key areas to check on how to access them for inspection and testing. I assume there is no fuse being it's the integrated power module. Any help would be awesome, thanks in advance.

Hello,

When you shift into reverse does the R illuminate on the dash or on the console? If it does not, then what you could be experiencing is a transmission range sensor that could've gone bad. The sensor is located on the topside of the valve body; however, it can only be serviced by removing the valve body itself.

I have attached a schematic for the power supply of the module that corresponds with the sensor as well as the location of the sensor and the plug for further diagnostics.

What you should do is unplug the switch and verify that there are no terminals that have any corrosion or damage. Then you can start checking the wires back to the PCM for continuity to ensure that there are not any breaks.

Let us know what you find,

Dustin

Well, they are illuminates on the dash but the lights on the shifter haven't worked in a while even before the reverse lights. Is it possible the TIPM is bad or other areas where a connection to the reverse lights can be checked?

You can test the output at the TIPM and see if there is battery voltage at the reverse lights output. That would at least narrow it to either the wiring or the TIPM. Unfortunately, if it's the TIPM the solution is either replacing or repairing the TIPM. To test the transmission range sensor, you can just shift manually through each gear and if the dash and transmission shift into each gear the range sensor should be okay as it uses different switches in the sensor to activate different gears. Then to test the output from the TIPM you need to locate the White with light green stripe wire at pin 11 on connector 8 If there is no power out on that wire with the key on and transmission in reverse then it has a failed driver internally. Replacing it isn't that hard, you disconnect the battery negative cable, then release the clips and lift it up. Flip it over and disconnect the battery studs and the connectors. Now install the replacement and reconnect everything. The next step is critical, turn the key to run and wait 15 seconds. Now turn the key off and back on. Test vehicle operation.

Okay, thank you, I will check that for power. Are there any areas of the vehicle where there's an interconnected that may have come loose in case it does show power at the TIPM?

There are a couple splices, one in the left front kick panel.
