Additional information is required.

What model year Cherokee ?
what engine size, gasoline or diesel ?
what transmission type automatic or 5-speed ?

Besides No-Bus what else do you see or hear. Does the engine run when No-Bus is displayed ? Do the gauges function properly when No-Bus is dispalyed ?

From what I've read here, this is what I've gleaned:

If it won't start, your crank position sensor is bad.

If it will start, your gauge cluster is loose or the contacts are dirty. The gauge cluster uses two cartridge-style connectors that can come loose or get dirty. Try pressing in on the clear front of the gauge cluster. If it's loose, sometimes pressing in on it is enough to reseat the connectors.

If that doesn't work, it may be necessary to remove the cluster and clean the contacts.

Pull from the bottom on the center bezel. It's held in with clips and just pops out.

After that, take out the four screws that hold the upper dash in.


Take out the 3 screws at the bottom of the lower panel under the steering column.


You can then pull the lower panel off by hand. It's held in with clips like the center bezel.

Now pull off the upper dash. It's held in with clips. The two parts that will be difficult are getting the headlight switch through the hole in the dash and getting the rubber collar off from behind the steering column. The rubber collar fastens in the bottom. Take it loose and pull it out from around the plastic cover.



I removed mine completely because it was a pain in the ***. I also slightly enlarged the hole in the dash for the headlight switch to make future repairs and mods easier.

Once you have the dash off, there will be 4 screws holding in the gauge cluster. Take them out and the gauge will just pop out. From there, it will be obvious what connectors to clean.

not the connector on mine

Same problem - instrument cluster goes on and off randomly. went so far as to solder each wire onto the pins to rule out bad connector. Checked crank position sensor, and a couple others, battery connection, etc.

Gave up and paid the local shop Almost $300 to diagnose problem. They say it is the cluster itself....

So now I'm looking for a used cluster.

Anyone got an extra cluster for a 2000 Cherokee Classic/sport?

Ok, just got signed up. I see there are lots of no bus threads, not a good sign...I recently bought this 99cherokee as my daughters 1st car, thinking it was a gem with only 84k on it...it had some history of key problems, and guage problems which the good Christian lady assured me were fixed after they'd spent over 1100 bucks on it...All was ok for a month or so, but it's now showed some of the probs from before with no bus, guages dead, check engine, key lite, etc. but so far no non starts or start/die scenarios altho she did report a start then die after approx 20 sec. when she went to put in gear...I'm guessing that may have been just a stall, cuz it fired right back up. PCM and SKIM units have both been replaced, and connector splice mod done to guages...what's the best thread to follow based on those symptoms??? The key problems resulting in no starts or dieing are what most concern me, glitchy guages I can live with...

2 types of NO BUS occur on the XJ.

1. NO BUS and engine doesn't start. 99% of the time, this is a shorted crankshaft position sensor.

2. NO BUS and the engine runs fine. This is a cluster issue, NOT a crankshaft position sensor issue.

For flaky NO BUS that don't correlate with engine no-starts or symptoms, concentrate on the cluster connections AND GROUND.

You mention only one stall so I wouldn't correlate that directly unless the NO BUS was present AT the time of the stall.

Disassemble, clean the entire circuit with some electrical contact cleaner, use some dielectric grease (this is very important in this fix), then reassemble. Some good info. above.

Most (not all) see a fix with this.

Thanks, TJ, I've seen you on these threads, and yer sig sez it all, right there...as for the key probs i.e. start/die and key light coming on, has that been a particularly frequent problem on these jeeps, not just cherokees but all with the SKIM option??? That's the one that really has me worried, don't want to see my daughter stranded due to skrewed up anti-theft system...as I said previous owner had problems with that, so far daughter has said it did one start/die instance(I forgot, she did report that it did do that once) and the other instance which prolly was a stall, I'm guessing...I suppose I'm looking for either reassurance that key probs aren't common, or verification that I need to look into this further...
