Pinpoint Test F : U0151:00: Notes
Refer to Module Communications Network for schematic and connector information.
Normal Operation and Fault Conditions
With the ignition ON, the RCM sends messages to the ABS module over the HS-CAN2. If the ABS module does not receive these messages within the specified time frame, the ABS module sets Diagnostic Trouble Codes (DTCs). This can be due to a RCM failure, a circuit failure on the network or an excessive load on the network. For information on the messages sent to the ABS module by the RCM, REFER to: Anti-Lock Brake System (ABS) and Stability Control - System Operation and Component Description .
