Check engine light wont come on.

camo · **Posted:** Fri May 06, 2011 6:59 pm

Hey guys, need some help. I already went through the forum and could not find anythig on it. My check engine light wont come on at any time at all so I took apart the instrument panel and found out a busted LED, dont know how it happen but I was wandering if anyone knows whaether it can be replace or do I have to replace the whole instrument panel? any help is much appreciated. :roll:

The parts fiche doesn't seem to having any replacement LEDs for the instrument panel.

Can you find any markings on the LED? An electronics supply place might have a suitable replacement.

Any chance that the CEL was intentionally disabled by a previous owner to facilitate selling the vehicle, or to pass emissions testing?

Consider your self lucky, one of mine has a bad CEL bulb as well.

its hard to tell... I dont see any markings on or arround the printed board of the instrumant panel and I cant read any number on the other similar LEDs to determine what kind is it, I call a chrysler dealer and I specifically ask the guy for the light which is really an LED and he said they had them, but even if they have them I dont see how can I replace it since it is soldered to the printed board of the instrumant panel.
Where can I find that parts fiche at? is it online?
thnx

I would goto a junkyard and grab a cluster to tear apart for a few LEDs and then solder the new one to your cluster.

Lots of people will be glad that this is in the CRD section when they are searching for help.

An LED is and LED. If you have any tech experience or know someone who does, go to Radio Shack and find one of the proper size. Make sure you get the polarity right.
You should not need $XXX of instrument cluster for a $0.XX part.

You need a code reader or one of the local auto parts supply houses can scan it for you, Autozone and Advanced Auto Parts are a few that will do it for free.

Where did you get the LED to fix it (salvage panel or electronic store and if the latter which one and what LED part #)? I ask simply because others have run into similar issues with respect to instrument panel LEDs, which I was pretty sure could be replaced, and it would be good to have a LED and solder fix as opposed to a $700 panel replacement.

Camo I presume you purchased your CRD used and the CEL light never worked correct? If so it was likely broken by the prior owner to turn it off. Which makes me suspect once you get the codes pulled you are going to have to fix the underlying problem that caused the CEL to come on. Hope that goes well.

I'd be interested in the LED specs as well. The light behind my fuel gauge has been dead for a couple years.

papaindigo · **Posted:** Fri May 13, 2011 10:56 am

Just to get it out there in the discussion. Our instrument panels have 2 kinds of lights (I'm not counting the blue-green digital Vacuum Fluorescent Display for the odometer); 1) LEDs, which is what I'd like to know the specs for DYI soldering in replacements, that basically function as warning lights and only briefly come on in bulb test mode when the ignition is first turned on otherwise they are off unless delivering a particular message like CEL or low fuel and 2) general illumination lights that light up the instrument cluster ONLY when the headlights are on. The latter are standard replacable bulbs (#103 per the owner's manual) and if I am counting correctly there are 9 of these. Instrument cluster removal and regular bulb replacement are addressed beginning on page 8J-93 of the 2006 FSM and at http://www.jeepkj.com/forum/showthread.php?t=26151

chrismc - I'm guessing but if your fuel gauge is not illuminated at night it's a burned out standard replaceable bulb.

Comment for all. If you are replacing 1 general illumination bulb I'd strongly recommend replacing them all and doing so with extended life bulbs. Pulling the cluster is a pain so might as well only do it once.

Thanks, papaindigo!

chris remind me later via email and I will take some pictures and pull the bulb for you, I have a cluster sitting here on my shelf so its easy for me to check out what you need for yours. can't do it right now as I gotta run and I will otherwise probably forget.

I got it fix a place call Houston speedometer not far from me, the only thing is that the guy had to put a red LED instead of the amber color (stock), so I have a mooded CEL :mrgreen:

Yes I bougt the car about a month ago and the light had already been disable so now that ii is working sure enough is bright on all the time

about the codes.... well, I just order an OBDII reader so I can check them and start correcting whatever I can

There's a instrument cluster test that can be invoked by holding the trip odometer button while turning the ignition on. It will cycle through all bulbs and guages :jester:

At one time you could read codes on at least some but a flash eliminated that :ALONE:

Check engine light wont come on.
