Medium and Heavy Trucks
Have Truck Repair Questions? Ask an Expert
My name is ***** ***** I will assist you.
Catman is the CAT engine guy and he will be able to assist you on this question better if this quick check isn't the case. On the tool, be sure you select the J1708 protocol for the CAT ET program. Then check the fuses that the diagnostic connector fuse isn't blown. This will rule out the CAN BUS issue with the truck itself.
Return here and let me know if still a no go and I will let the CAT expert take over.
I will opt out to let Catman take over since he is the Cat Tech here.
It might be an issue in the CAT program and the engine, not so much the truck side. I do the truck side, he does the engine side.
I'll keep an eye on this.
