Hello all, I have a DG J2534 and a Snap-On Pass through IV(DrewTech). When attempting to flash newer Ford vehicles the FJDS comes up with a testman runtime error and will not proceed with flashing. Ford tech claims it is a equipment communication problem. Drew tech says it is the FJDS software. Both boxes will communicate as a scan tool on all of the vehicles I've attempted to flash. What is the deal? Has any one had luck reflashing newer Fords without the Ford VCI?
