Code Description

For complete wiring diagrams, refer to SYSTEM WIRING DIAGRAMS .

The messages sent on the CAN bus are distinguished by an identifier (ID). Each CAN ID is defined to contain a certain number of bytes. The Anti-Lock Brake Module verifies that it has received the proper number of bytes for each ID.

• When Monitored: 

  Continuously with the ignition on, one valid CAN ID received at least once.

• Set Condition: 

  When the ABM detects an incorrect CAN ID from the BCM.
