No MIL (Check Engine Light) = FAILED inspection?! ------> SOLVED!!
I have been going through an ongoing saga of trying to get my Jeep inspected, and I failed again today. I failed before due to bad catalytic converters (codes PO420 and PO432), although my Check Engine Light was not on. I have now replaced everything from the exhaust manifold back with stock components. I went to get it re-inspected today and the cats are good. However, the inspection failed because my Check Engine Light will not come on. A fellow JF member helped me walk through and diagnose that the light is not properly functioning here:
It looks like the TJ instrument panel changed during production. I have a 2004 TJ and my panel is different than the one pictured in that thread. I have fewer bulbs than in that panel and the ones that I do not have appear to be in the locations of warning lights. Please see the pictures below for comparison.
The 2004 TJ has LED's, NOT bulbs. The FSM says they are not serviceable. Being an ex electronic Tech I would say that they probably are if you have the soldering skills. The more difficult problem would be sourcing the replacement parts.
Beer is the answer - it doesn't matter what the question is!
Assuming it is an LED, how would someone have gone about diabling that light? The picture above is as far as I disassembled the cluster because I was cautious about opening the white plastic housing. Any harm in going in further? Has anybody opened that before, and if so, would a broken LED be recognizeable?
a 'burnt out' LED is extremely uncommon most low power LED's have a burn life of 50,000 hours. to repair it you'd have to remove it from the board and solder a new one on if you can find something of appropriate size. it would probably be easier to just find a new panel
