ok here is my follow up. had to call local RAYMOND dealer to check out code 5D. according to them my model truck should not show that code. i believe it had to do with my truck not having "SMARTI SYSTEM" but the tech did not confirm that. however, he cleared the original software on the VFC and re-installed proper version of software and code is now gone. truck is now operational.
