Hey all,
So today my check engine light came on. A couple of minutes afterward I got the No Bus code and the gauges dropped out, etc, etc. As I typically do, I banged the dash like Fonzie and it solved the No Bus problem (guessing it's the instrument cluster connection). This time, though, check engine stayed lit. I'm new to this and I'd like to know if there's any stuff I can check myself before I have my mechanic look at it. Btw, it sounds and runs great.
Thanks,
Mill

 

Go to advance auto/auto zone/etc and have them pull CEL and then report back and next time you have to give the year and engine and such of your jeep

 

Will do, thanks. Btw, 99XJ 4.0L

 

Push firmly on the cluster straight into the dash, that's the most common way to fix that issue. As for the code, probably just stored the no bus code.

 

so Pep Boys said check engine was in reference to P0470 (TCC circuit malfunction). then on the way home the check engine light went off.

If you're gonna drive a 15 year-old truck (and a Jeep at that), you might consider investing $10 to $25 in a ELM327 bluetooth OBDII adapter and $6 to install Torque on your phone. Then you can read and clear those codes yourself. You can even click through the codes to see what information is available on them. Clearing the codes when you think you've solved a problem helps you to know for sure whether you succeeded.

You can get the adapter from Amazon. You get Torque on the Google Play store, and one subscription allows you to install it on all your Android devices. There is a code reader available for iPhone also.

I wish I had bought this years ago. Now I'm running it all the time on my Subaru to display extra gauges, and I will be running it full time on my XJ once I find a suitable used phone to serve as a monitor.

 

Great idea. Does this mean it's only an electrical issue?
