Just looking for some help for 2002 Dodge Ram 4x4 with 5.9L. My speedometer is not working and my SERVICE 4WD and AIRBAG light stays on all the time. Everything happened at once. Wondering if the ABS module would control all these items.

 

OK. No takers. Let me add to the story. I brought it to the dealer who convinced me it was the ECM. $800 dollars later he tells me it now must be the ABS module and wants $1200 more dollars. So now before I change out the ABS module I would like some input from someone who knows something about dodge trucks.
