I have a compass/temp guage above my rear view mirrow attached to the roof of my jeep (for those who don't look to the left too often, i own a 91 XJ Laredo) and i need to know if there is anyway to calibrate it and make it work to standards. can't find it in my chilton's, kind of vague on some the jeep models in there. i do know if i hold down the 2 buttons simultaneously (comp./temp and the standard/metric buttons) and 3 seconds later, the word "VAR" pops up and if i press the standard/metric button, it counts up from 1 to 15 (with each depression of the button) then starts over again. i know it does something with the calibration of the compass, because when i press the comp./temp button (appearently the on/off switch) for a second it turns off and when i turn it back on the direction has changed slightly (ie from E to SE or NE). the temp side says "OC" which i haven't a clue what it means (maybe a subliminal message to watch the OC tv series) ok lame joke, but anyways, does anyone know where i can find something online maybe to help fix or cal. it?? thanks!!

Depending on what part of the country you live in, (washington), those numbers divide the country into 15 triangular pieces. I have chiltons, but dont waste your time this picture is not in there. Someone here will tell you what "number" your state is. As for the temperature OC means Open Circuit. I suspect something is wrong with your temp sensor. (it is smack dab ib the middle of the front bumper, but behind it. Thats about all the information i can give you. Good Luck.

The VAR is the variance and for your area it should be set to 4. After you set the compass variance - drive in a clockwise circle a few times to calibrate it.

The OC is open circuit - either your temp sensor is shot (RockAuto.com has them for 20 bucks) or its unplugged.

Oklahoma is setting 6, except for the panhandle, which is setting 5. I would set it to six (or five) , then find a large parking lot, and as mentioned before, drive in a clockwise circle 3 times to calibrate it. Good Luck.

someone with a manual should scan that page and post it in here, and then get a mod to link this thread to the FAQ links.

i'd do it but i have no scanner.

i'll try to find the image online though

Sorry to dig up an old thread but I've been trying to find this info for ages....

My temp. always reads "SC" (1990 model) or reads completely wrong, I'm gonna guess that means "shorted circuit" but I don't know for sure. Where is this part located on rockauto.com? I only see the coolant temp. sensor listed for my year, I'm assuming this is a seperate ambient temperature sensor....

Thanks a lot, this thing is driving me nuts!

[madrabbitt]

have you tried to calibrate it like this thread said?

[sean87xj]

Yeah, the compass works fine -- just the temperature gauge is out of whack

The p/n of Rockauto.com is TX49. Take a look at more info for a pic and see if thats what you need. http://www.rockauto.com/catalog/x,carcode,1180011,parttype,7000 It shoiuld be the top one listed. Hope that helps!!
