Post subject:  Need help diagnosing our ailing 2006
About a month ago I posted a question about the dashboard disco I had going on. Nothing seemed to be wrong, no codes would show up when it was taken in, nothing weird was happening, and there wasn't any water in the fuses as someone had suggested.

Now it's acting stupid. I read in the service manual that a loose or bad gas cap can cause the MIL indicator to light up. The gas cap doesn't seem loose or nonfunctional in any way, my MPG isn't fluctuating or getting worse, and there aren't any weird noises. However, the GASCAP chimes at me about every five to seven minutes, and I've noticed some sluggishness on the interstate when I try to pass.

The O/D OFF, TRANS TEMP, and MIL are all still illuminating sporadically for less than 4 seconds every now and then. Over the course of a 40 mile drive home, I may see the TRANS TEMP light once, the MIL 3 times, and the O/D OFF several times. The triggering event seems to be deceleration, as I take my foot off the gas pedal. Braking doesn't trigger anything. Every now & then the tach will spike about 1500 higher for a millisec and then go back to normal. What the HAY is the Jeep doing?

Wow, thanks-----hadn't seen or heard of it until you posted it. Is that a TSB?

Yes it is, see reference number: 08-016-07. My buddy at a dealership gave that info to me :SOMBRERO:

Thanks.....I read up on complaints related to that TSB & it sounds exactly like what's been happening. Libby's in the shop this morning for this problem.

I'd had it checked twice & it wasn't throwing any codes, which is exactly what other peeps had said.

Just talked to the dude at the shop. Said he couldn't get it to produce a code after driving it for 30 minues. He's reprogramming the BCM and doing the battery-disconnect.

Basically, it doesn't really need to be replaced if it's just annoying me, right? It won't cause any further problems like engaging or disengaging other stuff like the ESP, ABS, etc, will it?

Well it's a TSB put out by Chrysler to remedy the dash light flicker problem. He told me yes the battery disconnect will work sometimes but the BCM really should be replaced to avoid further troubles. I know the dealer replaced mine even though they didn't have the problem occur on mine while they had it, it was also free to me when it was under warranty. If your under warranty and at a dealer, bring the TSB to their attention and they should do something about it if your under warranty still. But all dealers are different as to what they will and wont do for their customers.

Nah, warranty is all gone. I purchased it used. Only cost me $90 today for everything, so that's really not too bad. So far, husband says the problem is gone. We'll see if it resurfaces. I'd rather spend $$$ on a lift than a new BCM. :-)r

Update: 6 days, and so far so good. Reprogram appears to be working.

I freaked out Sunday, tho......was driving home & one of the chimes went off. I nearly punched the dashboard until I realized that the "ding" was for real and that I was almost out of gas. :oops:

Mine has done it twice in 65,000 miles. Once at 14K, and again at 49K, In both cases, I turned it off, cycling the key, and back on. I knew it was the BCM trouble, but it has no driveability issues. Just headache issues.

Yep....I had tried all the key cycling maneuvers first, hoping to stay out of the shop, but I just couldn't take it anymore. It had been doing it every 5 to 10 minutes & my drive is 50 minutes one-way to work. I was desperately close to earplugs & a black cloth over the instrument panel.
