Sounds like a dealer here.. throw parts at it till it's fixed.. Didn't cure 180's spoiler.. my abs decided to error and erect spoiler one morning.. yes oem white top. Per the manual the system looks for 12 volts for the abs system or faults. Tested mine.. 12.8 volts two hours sitting after a drive... 12.25 volts when ignition is turned on with stereo on (typical starting scenario). So "per the manual" I'd say my battery qualifies as suffecient for abs activation and function.. but she don't work.. another member had "simular" issues the other day.. was the sensor under the consol (yaw sensor I do believe) went bad. So "buy a battery" is not the absolute answer. A few member have had wheel speed sensors go out.. bought 4 of them from mr mopar - johns totalled car.. so eliminated that possibility too.
