2011 Dodge Journey Mainstreet
The driver side tail light and reverse light assembly is not getting power. Tested by plugging in opposite side. No visible signs of wire damage. Not sure what to do next. Tempted to splice into passenger side as it is only powering tail light and reverse light - both sides would always function together anyway. Any thoughts from the pros out here?

Much obliged!

 

Very first to do is reset CanBus by disconnecting battery at negative
jumper post for 15 minutes.
The loom from the cabin to the gate has been reported (usually 2009-10 models)
have a broken wire just from opening closing.

 

Thanks for that info. Do you know where the break typically occurs? I'm assuming where the gate hinges? Also, resetting the CanBus; what will that resolve specifically - would it assist with identification of a break?

 

With regards to the break in the wiring loom no specific indication of where occurs ,
you will have to move the rubber boot that covers it and check physically.
The DJ as well as other Chrysler (FCA) vehicles use the network system known as
CanBus , controller is the TIPM (totally integrated power module) which is part of
the fuse box assy under the hood.
When you disconnect the Negative and wait until the system discharges then reconnect
it reboots the TIPM and quite often clears electrical gremlins that it causes and no it won't
help find the broken wire but will clear that possibility of a TIPM problem.
It will not bother your radio presets.

 

This is a tad late but thought I'd provide an update. The issue was in fact broke wiring within the wire harness. 8 of the 15 ish wires were completely severed, 4 on the verge. Only 3 wires were fully intact. Personally, Dodge Electronics/Wiring team (or whatever appropriate design team) should be more investigative when selecting wiring especially on a family vehicle where rear hatches, gates will consistently be cycled up and down. More rigorous testing needed!

Thanks for the advice on where to look!

 

Thanks for the post about your problem being resolved.
I would think this is a potential point of trouble for any
"hatchback" with active lighting on the door and again
one would think it is taken into account during design.
