It’s reading that code 0601 saying pcm. I’m worried that the van is shifting weird from first to second and it’s like when slowing down almost to a stop the brakes are like locking up for a split second? Those issues common with the 0601 pcm not working properly ---

Over the years [allpar.com](http://allpar.com) has provided me with lots of help with our 1999 Voyager and 2007 Town and Country. They have a discussion group devoted to minivans and Pacifica. You might find vehicle-specific info there. ---

> [@Vic2018](#): > > Before replacing it. I would like to know 100percent that’s what it is If you read the article Tester linked to, you would see it could be just a bad ground connection. If it’s properly grounded and giving the 0601 code, it’s a bad PCM. > [@Vic2018](#): > > is my transmission slipping and brakes locking up have something to do with it If you read the article Tester linked to , you would see those are some of the possible problems with a bad PCM or a poorly grounded PCM. ---

There are times when a factory wiring schematic is invaluable. I can’t help you with that. I have tons of wiring diagrams but none for a Chrysler van. ALLDATA is a possibiilty. Your vehicle can be enrolled (unless it’s changed recently) for 25 dollars a year. Wiring schematics are available on that site. That could steer you to any pins involving grounds and also which fuses control what power sources.
