My Case Tr320 popped code 3210, "general short circuit on bank 1 injection cable ". I guess I'll tilt the cab and look for a frayed wire. Any other tips?
Thanks Scott
Took all connections apart blew them with air, disassembled the Junction box cleaned and inspected. Found a friend of a friend that deleted the codes and reprogrammed the computer. Running smoothly for 10 hours now!!
