What issues are you having? Have you gone through the troubleshooting section of the FSM?Hey friends,
I have a 2006 TJ automatic. I have had my car for 12 years- bought it brand new and never had a problem with the PCM. I actually never had ANY issue with the jeep until it hit 11 years old- always ran beautifully! And this is has been the only car I have owned in 12 years; it runs everyday.
So after switching out a handful of parts in the past few weeks I am still having issues and believe it is the computer and am having issues finding a place locally to fix it without spending a fortune. Has anyone had any luck with the plug-n-drive replacements? Give them your vin and no additional programming required??
I may be 2 years too late but I thought I’d chime in with my PCM experience. I have a 05 RUBI a/c and a/t. I got the CEL after my Jeep started running rough. I got several codes. Cat was bad, both upstream o2s were showing up bad and a fuel injector. Replaced cat, bank 1 on old one was collapsed and plugged. Replaced all o2s but both upstream remained inactive. Thought maybe it was PCM. Long story short. Before I dropped huge money on a new PCM I decided to physically check my wiring from pcm to each and every plug. Not far from the PCM, where the accumulator is the wire loom rested over it. I put my fingers under the loom there and found a hole that the vibration of the motor wore a hole into and severed many wires throughout 15years Well hidden disaster. I unplugged the battery and all 4 plugs going to PCM and started repairing wires. When I finished I plugged everything back in, started it back up. The Jeep ran smooth. No CEL light, no codes. I fixed the problem. It wasn’t easy to find. My Jeep was down since August 2019. My original PCM has 168,000 miles and still going. It’s not always bad components, it could be broken wires or both. Hope this helps.Good luck fellow Jeepsters.So the other day a problem returned that I hoped never would. The PCM problem in 05 and 06 automatics. I was wondering if anyone has taken they're Jeep to a dealer and they flashed it.

For now, every few weeks or so when it starts messing up, I reset the PCM and it fixes it usually its a few months but sometimes it could be a few days. It is very strange to say the least
I just disconnected the negative cable on mine when mine started acting up. It started out every now and then, sometime months between episodes. Eventually it got more and more frequent to the point of almost every day. I got a PCM from @Wranglerfix almost 1 year and have had no issues since.

hey know its an old post — did you ever find a solution or flash your PCM at dealer? cousin has identical issue; after reading seems like best option to fully fix is wranglerfix pcm, but at the same time there are few posts to find stating that a flash didn't work. most posts say people are going to try something then we never hear back!
I don't recall ever seeing anyone say a flash worked for the long term. I could be wrong though.
were you having PCM related issues? Or mainly just the CEL?I may be 2 years too late but I thought I’d chime in with my PCM experience. I have a 05 RUBI a/c and a/t.

I've been having hard shift issues for a few months now. And just 4 days ago CEL. But in theast 4 months, I've had to change the starter fuse twicewere you having PCM related issues? Or mainly just the CEL?
