I got an 06 CRD Sport, 105k on it all maint. is up to date, just lifted it with ironman coils and springs with rancho struts and shocks for now, i got JBA UCAs JBA clevis ring half inch, and JBA Strut spacer all sittin on 15x7 all black daytona style wheels and 31x10.5 all terrains! but thats all good. my problem is today when i went to start it every thing started fine but all my break lights (e brake, ABS and ESP are on and i cant turn off traction control) as well as my CEL and my Spedometer and RPM gauge arnt working either but my gas, odometer, temp and every other electronic is?.... any reason as to why or how to fix?..... Please help me any one

I would start with the front two wheel sensors. How long after lifting did this happen? Also you might want to move this over to the CRD section.

Agreed on the ABS sensors (although I think some of the gauges you're reporting issues with trigger off the rear). Also moved.

wiring harness to rear wheel sensors contains too thin and too short wires. You probably have a break in the wire feeding one of the rear wheel sensors.

I suggest you get your codes read to pinpoint which wheel is affected. replace the wheel sensor first (easiest thing to do) and then if not fixed, start checking wire continuity.

good luck. I've had this issue 3 times. first time was broken wire to right rear wheel sensor, second time was broken wire to front right wheel sensor, and last time it was water getting to plug harness causing intermittent problems-fixed with liquid tape and silicon.

This is why I prefer the ABS on the 2005. Fewer ABS sensors (by one) and it's right in the middle.

Just ran everything no censor problem all lines are good relays and what not so idk what issue is still all lights on and gauges not working weird doo doo

Are your rear brake lights still working I had an issue one time with pinched wire for my tow lights blowing a fuse. And it was activate my abs lights everythime. I would double check my fuses in the jeep mine was a 15 amp and labeled rear lights or something odd like that. Also how did you check the sensors exactly?

Ya... All my lights work, all fuses are good, cant find a short in a system. I did gauge reset and all gauges work but when vehicle starts gauges stop and lights come on, like i said I can find any thing, the CRD run like a champ and purrs like a kitten even though these issues are occuring and I am at witts end here...... pluged it in to my obd reader not a single code... so I just dont know, unless any of you know a good guy here in el paso to help other then that im stuck trying to rosseta stone with a mechanic so we can get on same page..... and every stealership wont touch because its a CRD.... I need some darn help....

I'd still lean toward a bad speed sensor or a broken (inside the insulation) speed sensor wire. I don't know how to diagnose a bad speed sensor but you can check the wire for continuity based on the pin outs on the wiring diagrams. The 06 has a speed sensor for each wheel (05 had 2 in front and 1 on the differential in the back for both rear tires). When a sensor(s) go bad the brakes/ESP/etc go nuts. I also recall a bad wheel hub can cause a sensor issue but don't recall the details.

FYI the wheel sensor issue is not repeat not a CRD issue as all 06 KJs have, according to the FSM and owner's manual, the ESP system that requires the 4 sensors. Any decent auto electric, brake, or steelership should be able to diagnose the problem

well took it to dealership and ya.... aparently electronic control body or module in the transmission. if this goes out then you speedometer and rpm gauge will fail along with the kicking sensation when gears shift and will also throw up every light in the CRD. so 1200 later its out an runnin like a champ! BTW not the T.C. its in great shape.
