Normal Operation
The RCM communicates with the diagnostic tool through the international standards organization (ISO) 9141 communications network, circuit 70
(LB/WH). Check circuit 70 (LB/WH) between the RCM C310a and the data link connector (DLC) C251. The total resistance value must not be more
than 5 ohms. If the resistance is more than 5 ohms there is an open in the ISO 9141 communications network circuit, damage to the DLC C251,
damage to the RCM C310a, or a problem in an in-line connector.
