Question
QUESTION: ABS brake light flashes when first running, then stayes on. I've pulled 7 DTC. not sure were to start? codes are #22 Rt.Frt.Sensor signal (has signal when driving with scan tool, matches left side) #51 Foundation Brake Partial Sys.Malfunction #52 Rear Dump Valve Solenoid #74 Driver Control Mode Timeout. #78 Foundation Brake Partial Sys.Malfunction. #82 Tone ring teeth factor out of range. #83 Tire Revs per minute Factor out of range.

ANSWER: The first thing to check would be the connector at the brake controller. There have been cases where water has seeped into the connector causing poor connections and under severe cases corrosion of the terminals. With that many unrelated DTC's I'd be more inclined to suspect a wiring or controller issue.

QUESTION: Thanks for the advise, is there a way to check the controller, the connections were all good and clean. The controller is on top of ABS pump,servo assembly? Thanks again

Answer
You really can't check the controller directly. Testing for a failed controller requires having access to Chryslers DRB III diagnostic tool. Your best bet would be to take it to a local dealer and have them run the tests for the codes 82 and 83 that you retrieved. The tests will check whether the controllers memory can be written to and then read.
