I dont believe i have had this issue on any other truck, yet. I can watch data on the transmission side. I can check and clear engine codes. Not able to see engine data due to "no communication". It wont allow me to access functions such as disabling injectors, wait to start light, ect. Also not able to get into the cluster either. Same issue with two different scan tools. Was hoping someone has ran into this issue before i spend all morning checking wiring and it be something simple. Thanks What are you using to watch data?

Have a late 02 ran 2500. Cummins automatic 4x4. Truck has a issue believed to be failed MAP sensor. Tried two different scan tools and neither connect to the Engine. I can communicate with PCM and watch data on the scanner. It wont let me communicate and watch data on the Engine side. I can check engine DTCs but once I hit DATA DISPLAY it says no communication. Have checked and all fuses, and wiring appears to be perfect based on a quick visual inspection. Have not pulled out the DMM yet to check. Engine starts, truck runs. OBDII has power. Anyone ran into this issue before?

I have a 2004 ram 2500 slt 5.9 automatic. Truck has ABS code 84 Vin Mismatch. ABS and Brake light are on and of course ABS does not function. No other codes in the truck at all. Every place I have called which repairs ABS modules, says they can not repair that issue. Chrysler discontinued the part. Supposedly it needs programmed. Local dealership said they can not re-program the ABS module. I have read you can swap it out with one from another truck as long as the part number is the same. I pulled one out of a truck my neighbor has and the part number is the same. Issue is still present. Anyone have any input on how to resolve this issue? Checking wiring diagrams, does anyone know which wire the module uses to pass information to the ECM? Or if they even communicate to each other to verify VIN? Any and all help would be greatly appreciated! Thanks
