ok today i was tinkering with the two buttons on the computer compass thingy and held on of the buttons and it went blank and then had 'var' and a number '1' next to it. as i pressed the right hand 'u.s/metric' button the number went up every time i pressed it all the way to 15 can anyone tell me what this is for. also regarding a previous question where the temp is supposed to be it says 'sc' if i were to change the sensor would this solve the problem, and is the sensor the thing attached under the hood right at the back. thanks

 

THat will allow you to adjust the compass variance for various regions..Where are you located and I can give you the proper variance number you need for you compass straight from my owners manual..Also if I had a scanner I'd post a pic for you..I'll try to find a map in one of my pdf's..

 

thanks, im in the uk. you know anything on the 'sc' problem?

 

To quote the FSM...

My guess it the sensor is bad it is located up front by the bumper area...

 

SC stands for a short circuit in the ambient temperature sensor or circuit. The region you are in is 10.

 

thanks ill set that and have a look for the sensor in the morning.

 

and thanks for the info okcjeeper

 

Any time..

 

Let us know if ya get it all fixed up..

 

Hey how's it going? I'm in Texas. Dallas, TX to be exact... Do u know what region I would need to be on in the OHC display? I just installed this and want to make sure I'm in the correct region cus my compass is acting a bit weird. Thanks in advanced

 

On a side note, would all XJ's have the circuits needed to add an overhead console? Don't want to rip things apart unnecessarily...

 

It should be in the owner's manual. But according to mine... variance for Texas is 6


97+ yes. 96 and older... not 100% sure. For the 97+ all they need is power, ground, CCD signal and the 2 wires for the temp sensor. I would imagine the older consoles are similar.

I had an issue with mine a few months ago. I posted troubleshooting steps I hope that can help you get an idea.

I would've looked but the PO didn't give me the owners manual... :-(

 

Ah

You can also google "Jeep Variance" and look in images. A map of the compass variance should be the first picture.

 

Thanks a lot!! It was late last night and didnt look very well online lol...

On another note... I found out that BMW temp sensors have different resistances than jeep sensors... My temp gauge was reading 94deg farenheit when it was really 64 outside hahaha
