Once the car has warmed up for 15 min or more, turning it off and restarting clears the problem until the next day (days are not that cold in Calif). My code reader shows P0720 & P0600 and I delete them and of course they come back the next day I start the car. I already tried replacing the (original!) battery. Anyone else resolve this issue or have any ideas? Help would be greatly appreciated
the problem is your abs module you have 3 options to fix
1. replace at dealership around $1,900
2. order an new abs module on a mopar web site around $800
3. replace with a used abs module $ 250
I replaced with a used one and it works fine you can buy at a local junk yard or on ebay
