Before you go ripping your interiors apart do yourself a favor, pop the hood and check the condition of your main body ground off the negative battery terminal
MAN! I just bought a 2001 Jeep Cherokee and had the No Gauges and the " NO BUS" alert. I am going to try this and see if it fixes my issue! thank you so much for posting this!!!
Thanks! Took me 5 mins no exaggeration to take the cluster out. Chrysler really made these things nice to work on. My terminals behind the cluster looked clean but I had already bought the spray and sprayed the crap out of the plugs and harness as you said. Then I used some compressed air to blow everything dry. Put it all back together and it’s working perfectly!
Thank you for posting this! When I started my 2001 XJ yesterday, I got the dreaded "no bus" odometer and had no gauges. The engine was running just fine, so from what I've read that means the issue is a connection fault between the cluster and the ECM. Was definitely NOT looking forward to having to pull the cluster but you're video really helps by showing where the screws and the hidden clips are located, and how to remove the dash components. Again, thanks- too many people take these "how to" videos for granted. Your work is appreciated. Now... to get started on doing this to my Jeep!
Thanks for the video, found it extremely helpful today. 20 minutes into a 9 hour drive home from Yosemite I lost all instruments and the check engine / no bus light came on. Everything ran fine, so i drove a while to an auto parts store, picked up some electric connection cleaner and did the procedure, worked like a charm and got me home.
Thanks a million for this. While I was in there I popped all the bulbs out and cleaned them up too -- they all had that white dust on them which was making them dimmer.
There is a technical service bulletin on this from jeep. You need to replace the connector on right side. The connectors are getting corrosion on so cleaning will work it specifically says not to use sand paper ,file or knife to clean. It removes the protective coating from the connectors.
Yeah lol so they can take your money . They also say you cant fix your own pcm but you can turn in your old burnt core and still have to buy a whole new reman pcm. No core? Core charge
1999 jeep XJ October 2017 update on No bus error. On my 2nd PCM and I'm still stalling. Found a simple and stupid solution, when the jeep stalls I jiggle the 3 multi wire connections to the computer pushing the cables into the connections and lightly tapping on the PCM so far it worked every time.
on my xj .. the power door locks quit working while on passenger side. works fine while on driver side. did all the usually clean connectors checked grounds and fuses. on mine is was in the over head dome light. there is 2 plugs inside unplug the big connector . every thing comes back on check engine light goes out and abs. leave it unpluged . when you plug it back up you hear power door locks work and no bus will return. the big plug is for keyless entry leave it unplugged. my no bus has not returned.
after purchasing 2 pcm's ( needed California emission type) after a few weeks same problem,stalls, no bus shows, my fix. open the hood a jiggle the wire harness to the pcm all 3 of them tap the pcm for good luck, and it starts every time
Apply dielectric grease to both haves of the electrical connection before reassembly, this should solve your problem, or at least make the fix last longer.
I have the same problem since yesterday ,but my flasher/blinker wont work either and when I turn off the light switch , my shifter (PARK,NETURAL,REVERSE,DRIVE,1/2) light turn on even if turn off the jeep and the electronic
I have a 1995 ZJ with a 4.0L that has some issues, and can't find a fix anywhere. The voltmeter gauge on the cluster will intermittently show normal charging (approx 13.5v), and then low charging (around 12v or below). When measuring with a voltmeter on the battery and on the alternator, the charging voltage stays around 13.5 to 13.2 at idle with a/c on, but the dash still shows low voltage. It only shows normal charging voltage when starting for the first time in the morning. Shortly thereafter, it will drop to approx 12v or below. On rare occasions while driving, the jeep will keep running, the headlights stay on, but the instrument cluster will lose power, the stereo turns off, and the a/c turns off only for a split second like it cycled power or lost bus connection due to irregular voltage readings at the cluster (I think?) and then come back. Shifting becomes irregular leading up to the power cycle and RPMS seem to be held out a little longer in between shifts when it reads low voltage on the dash, right up until it loses power and cycles, comes back, and pops back up to approx 13ish volts on the cluster, and seems to run fine again for a short while. It keeps running, it drives, it starts, it gets me where I'm going, and doesn't stall. Alternator is brand new, battery 6 months old. I know it charges according to the volt meter, and it never has sluggish starts or issues starting, it will just randomly cycle power on the instrument cluster. I can't find a write up on this anywhere.
NS wish I could help but have never had a problem like that. Check your grounds and the connection at your PCM. I would recommend getting some of the xj Jeep forums you can find a ton of stuff on there. The plus side is if you join you can ask questions. Wish I could be more help.
and what if you've done that and it's starts all over again? then what? going through this now. pulled everything it worked on a off for month now No Bus again and none of the gauges have worked in weeks.
Mine did it again also about a few months later. I just took it apart and cleaned again. Works for now. I don't know man you might have to get a new cluster.
So my 1999 xj I changed my heater core and after I plugged everything back in and tried to start it, it started and ran for about 5 seconds then died then the no bus popped up would that be caused by the just bad connection in the gauge cluster?
it's not that my friend, the solder joint break inside the cluster, so you really didn't fix it!! your problem will be back!! i repaired a few already that's how i know!!!
So, I did this fix once and it worked for a day or two, but no bus came back. The terminals were pristine, but I cleaned them with Dioxit, sandpaper, mass airflow sensor cleaner, and then dielectric grease. I just took it apart again and no dice. the XJ runs great and all functions work. The ignition cylinder is broke, but that's all I can think of. Any ideas?

More than likely it will work.

Brad Brownfield Easy job to do. Sometimes if you jiggle the harness under the steering wheel it works also.
did this fix your problem
@@rennpart indeed it did

It will do it again sooner or later, put some dielectric grease on it next time. I have not had to do it again since I did that.
Did you ever have that problem again?
Hi, no i have not had this issue again.
Thanks a million for this. While I was in there I popped all the bulbs out and cleaned them up too -- they all had that white dust on them which was making them dimmer.
Glad it helped you.
Even better method - just push the entire cluster with both hand and you see the cluster come back to life hahaha

Thanks for your know how,we’ll try it.
i have the same issue, will b trying this soon. id recommend also... di-electric grease.
Yes good idea. I had to do this again about a month ago.
Headlight knob can be easily removed from the back.. a small button on the back of the switch will release the knob you can just pull it out

Thanks for the info. Sadly I no longer have my xj, the motor decided to retire
I'd recommend Sudafed. Not the fake stuff.
fastenol1 lol i know man Sudafed 12 hour works good
JUAN DEGOLLADO. I got it bad too brother. 12 hour, the best indeed. Now, back to my NoBus.. Stupid thing!

Good to know mine never stalls just gauges don't work
Best video yet,. Will give it a try thank you
coyotekillermiller Thanks hope it works for you

You can grab both bottom corners of the center section and gently remove it, easiest way I've found.
Thanks for the vid. 👍
great video, thanks.
Travis Bohanan glad it helped
Looks like a dependable PCM new/rebuilt are hard to come by for the jeep XJ
Phil Jomidad oh yea a new one will cost you about 300 at autozone
I have the same problem since yesterday ,but my flasher/blinker wont work either and when I turn off the light switch , my shifter (PARK,NETURAL,REVERSE,DRIVE,1/2) light turn on even if turn off the jeep and the electronic
Hello bro,,,do you have any communication way to reach you out,,,i have an issue with my jeep,,,so please share any way to get to you
I have to tell I got rid of my jeep a long time ago but maybe I can still help you with something

I don't know man you might have to get a new cluster.
So my 1999 xj I changed my heater core and after I plugged everything back in and tried to start it, it started and ran for about 5 seconds then died then the no bus popped up would that be caused by the just bad connection in the gauge cluster?
I don’t think so. Im thinking you moved something in the wiring to your fuse box or computer module.
Muchas gracias, me sirvió muy bien.
Thanks for sharing bud
Hope it helps. I have had to do it once or twice. Put some dialectic grease on it.
I forgot to mention that it's a 1999 XJ. The plug that connects to the PCM could be faulty it's the plug that's closest to the front of the jeep
I wanted to see how to take the dash apart.
all this is all well and good but it is an XJ >2000 model
Did this still work??
NyQuil..
Hello, can I use wd40 to clean? Thanks for your video
I would think so. I have used it on a lot pf electrical stuff.
You should be able to. Everyone I know swears by it. I personally us electronic cleaner.
it's not that my friend, the solder joint break inside the cluster, so you really didn't fix it!! your problem will be back!! i repaired a few already that's how i know!!!
SiFiRocker solder where? I got my dash and wires and all kinds of bs apart. Cleaning and checking everything. Nothing is working
Did the jeep have shifting issues?
Hey man mine does the same thing but my stereo died too
Same problem here! Idk if its the grounding cables or what but I have the dashboard off and looking for solutions. What did you do to yours?
How bout taillights
@larry warren what do you mean about taillights?
So, I did this fix once and it worked for a day or two, but no bus came back. The terminals were pristine, but I cleaned them with Dioxit, sandpaper, mass airflow sensor cleaner, and then dielectric grease. I just took it apart again and no dice. the XJ runs great and all functions work. The ignition cylinder is broke, but that's all I can think of. Any ideas?
Any update?
@@highwayxj9397 Well, we just went through all the routine bs and it did stop. Probably a ground issue.
I did that..still nothing

What causes this malfunction ?
My guess, moisture dirt and grime get in those connectors. Those connectors aren’t sealed. At least it doesn’t look like they are.
@@juandegollado7808 would it be behind the gauges?
@@xxflyingwafflexx1802 it’s the connectors. I think the gauges are fine. The brass connectors just get corrosion on them.
