yes i see that now, need a scan tool to pull codes from this one
also the jumper method is possible, find the diagnostic connector and jump pins A and D , turn on key to on position and it should go into diagnostic mode and cause the MIL light to flash the codes.
This system on this truck also uses the spectrum PSI EDIS software so if you happen to have that cable setup that can hook up to this diagnostic connector it may interface with this truck. You just need to make sure it is the right Tier version of software. Either Tier 2 or 3 most likely.
