I had the service engine light, ABS light and brake warning light come on on my van. When these lights illuminated the odometer and speedometer quit registering speed and miles. I changed the speed sensor in the differential and unhooked the positive battery cable to clear the codes. After hooking up battery cable and taking for a test drive the service engine light went out but the ABS and brake light are still on and the speedometer and odometer are still not registering speed or miles. Any thoughts?

EnthusiastChange the ABS module.Will fix the speedo, but will have the ABS and brake lights still. If you do this yourself, be prepared to pay the stealership at least 140 bucks for them to flash the computer, which will turn off the ABS and Brake indicator lights. Or you can put a piece of black tape on your cluster display to block out those damn irritating and anoying lights!Being a lifelong dodge driver, I am thouroughly disaapointed with Dodge and the poor engineering path they have taken. Why would you run THE speedo pulse into the ABS module FIRST, before the BCM(body control module)Where the speedo needle display is generated. I understand WHY ABS needs speedo pulses, but I don't understand WHY the ABS module is in a poor place for interupting an essential path of an essential tool- the speedometer???
