Normal Operation
The restraint control module (RCM), vehicle security module (if equipped), and the anti-lock brake system (ABS) module (if equipped) communicate
with the diagnostic tool through the ISO 9141 communications network, circuit 70 (LB/WH). Check circuit 70 (LB/WH) between the RCM C310a,
the ABS module C135 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.
