Normal Operation
The RCM communicates with the diagnostic tool through the standard corporate protocol (SCP) communications network, circuits 914 (TN/OG) and
915 (PK/LB). Check the SCP circuits between the RCM C310a and the data link connector (DLC) C251. The total resistance values must not be more
than 5 ohms. If the resistance is more than 5 ohms, there is an open circuit in the SCP network, damage to the DLC C251, or damage to the RCM
C310a.
