Normal Operation
The RCM communicates with the diagnostic tool through the ISO 9141 communications network circuit 70 (LB/WH). If circuit 70 (LB/WH) becomes
open or shorted to ground communications to that module will not be possible. Check circuit 70 (LB/WH), between the RCM C310a and the DLC
C251. Total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms there is an open in circuit 70 (LB/WH), damage to
the DLC C251, or damage to the C310a.
