So, I'm hoping that someone may have some insight into this. It's been driving me bonkers... So randomly I'll get in my jeep and start it up and about 50% of the time it will shut itself back off after 2-3 seconds and displays "Service 4wd". You can always get it to run, but the number of times it takes to get it to stay on varies from 2-? It's getting very frustrating. I'm leaning towards the PCM. There are other funny things it does... Windshield wipers will cycle once when it's started. The automatic wipers work sometimes and other times not. I randomly will get the transmission over temp message and a shut down and restart will clear that. The starting part is the worst. I have to cross a ferry for work and when it won't start they make it into a huge ordeal. Any insight is greatly appreciated. At this point I'm thinking about trying a rebulit PCM, to me everything seems to random for it to be something else.
