2002 Jeep Grand Cherokee No back up lights in reverse

I have a 2002 Jeep Grand Cherokee.. 4.7L w/ 545RFE Auto transmission. When i put it in reverse i get no back-up lights. From what i get these transmissions use a Trans. Range sensor that mounts above the valve body. It will only start in Park and Neutral . Could that be the problem. No trouble code is showing up on a OBD II scanner. also below the odometer is the is the following A / S 1 2 3 4 5 ... These look like the should light up but they dont ? anything i should be worried about ?

what car, what country. usa,or export.
is the transmission NAG1 or 545rfe? (WK HAS 2)
we cant guess ANY OF THAT.
all jeeps , have rules
lets pretend you said, 2005 USA, wk grand Cherokee
and read chapter,8w. (WIRES)
what do you see, ?
GUESS NAG1. (MERCEDES)
if NAG1 the TRS is inside the transmission,deep
and can be seen here, "search for Reverse and N2 pin"
the same switch assembly runs cranking and reverse
permissive.
The German transmission is tricky
it uses a pressure switch (and funny logic)
to signal Reverse. yes ,very tricky, read nag1 chapter 21.

2002 grand cherokee, overland 4,7L engine doesnt


Hi Joko,

What you are describing is a failure of a main circuit. The first thing you should check is yo make sure that your battery is in good condition and that the cables are clean and tight. Let me know if yu find anything wrong there. Then there may be another main circuit problem. Check all of the fuses in your fuse block in the engine compartment. If any of these fuses are blown, it will usually cause several things to not work. If you find any fuses blown, DON'T REPLACE IT YET. Let me know WHICH fuse is blown and I can help you find out why it blew so you can get the problem fixed.

Get back to me on this and we will continue.

My 2001 jeep grand cherokee limited back up lights wont work. No fuse listed just for b/u lights.


You have a switch on the transmission that turns the back up lights on when put into reverse. It may need adjusting. It has to be done with carefulness. The car has to be in reverse and the switch adjusted at the same time until the back-up lights come on. It may be safer for a shop to do this unless you feel comfortable doing it.

2001 jeep grand cherokee wont reverse in


This could be an issue with the shift solenoid , but can also be caused by low fluid due to a leak, check your fluid. Is there a check engine light on, if there is it could be a solenoid issue.

No back-up lights on an 2002 Grand Cherokee 4.7L w/ 545RFE


On the side of your transmission will be a switch with several wires coming out of it. This is your reverse switch that turns on your reverse lights and most likely needs to be replaced
