I have parking sensors on my 2006 jeep grand cherokee front and back. they do not work any more. the computer is telling me to service them. how? I do have two red lights on the displays and i can't turn off the swich on the dash board.

WJ jeep USA.
fuse blown
or caused by trailer wiring rear, hitch, all mangled common
or past collision damged
front park lamps dead to or side lamps park dead/??????????????

only takes eyeball to see that.
or scan the PCM it will tell you why.
the service manual has the schematics for all that,
brakes + tail/park but blinks ok?
beside bad wiring, (I have A reAL WJ MANUALS ALL)
THE FUSE 6 IS BLOW
OR OFF F6 THE RELAY PARK IS BAD.
THE BCM BRAIN RUNS THE PARK RELAY TOTALY
SO BCM FUSES MUST NOT BLOWN, Just test all fuses. ?
BCM fuses are F7, f22, and f28, not blown./
the BCM must communicate on the network or fails
PCI bus is Jeeps name
if anything trashes this bus vast things fail.

if BCM is dead vast things fail over 25, and endless seeming list

not told you what does work? (telling only bad things only makes the job 10 x more hard.
scan and it tells you what is dead in 5min work. on most cars./.

Sounds like the batteries might be dead in one of the sensors inside wheels.. Also try to put air in all of the tires.. It should reset itself..

can i guess you replaced both for a buck? yes>?
tails are park , there are like 20 lamps on park
all are dead?
click TJ
and 93-98
then wiring
and read the schematic. see where to check voltages.
its that easy.

no computers no BCMs,. just 2 bulbs, a switch and fuse.

if the fronts work it is bad bulbs

google cleaning jeep grand cherokee shifter module its the same thing
or google grand cherokee or commander forums find a few and post this and all future questions there
if you are speaking of all the shift positions being surounded by brackets like [r] [n] [d] [l] than thats likely the problem the part can be cleaned its located beneath the shifter bezel or replace it the part is about 450 to 500 bucks but try the foorums i know ive seen a writeup with pictures there

where is the parking assist sensor??

Hello Debra Russ,
U may locate oil filter 4 2006 Jeep Grand Cherokee 2 way's.

1.) Open 2006 Jeep Grand Cherokee Glove Box, remove the 2006 Jeep Grand Cherokee owners Manual from glove box. Open owners manual to index page, locate oil filter page.

2.) Secure 2006 Jeep Grand Cherokee from moving fowards or backwards by blocking wheels in front and back which will NOT allow movement of said 2006 Jeep Grand Cherokee.

Using a small person of average build, average height, average weight, average intelligence, average physical appearance, move average said person with said average features of above near the 2006 Jeep Grand Cherokee, instruct said person to physically crawl under vehicle while laying on said person backside, (**** scraping on average dirty ground or average dirty filthy oil filled garage floor filled with oil filled kitty litter. Hand said average person an average shop light with an average wallmart brand soft white light bulb, light bulb will bo out very soon so move to next step ASAP. view engine while calling out all massive oil leaks INCLUDING a dirty oil caked oil filter.

Congradulations!
You found it when a black oil droplet drips from the oil filter into said average oil filled hair of said average person!

There is no way for you or me to tell. In order to determine what service it needs you should go to the dealer and they will perform a diagnostics test. I think it is around $95. It could be something simple as a fuse or reset needed. It could possibly be under warranty and not cost you anything but the $95.
I hope this helps

Use the owners manual and it will tell you what services are needed according to the vehicles milage.

The sensors are behind the rear bumper fascia, not sure about the fuse, the fuse box is under the dash left of the steering wheel, trying to sort through service manual now, you can grab one from promanuals.net for around 20 bucks though. Has complete component locations, over 7000 pages.

it can all be changed by using the overhead computer that tell you the temp, it is one of the options in there
