Normal Operation and Fault Conditions
With the ignition ON, the air suspension control module sends messages to the ABS module over the HS-CAN 2. If the ABS module does not receive these messages within the allotted time frame, the module sets a DTC. This can be due to an air suspension control module 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 air suspension control module, refer to the Network Message Chart in Description and Operation in the Anti-Lock Brake System (ABS) and Stability Control article.
