Normal Operation and Fault Conditions

With the ignition ON, the PSCM sends messages to the ABS module over the HS-CAN 2. If the ABS module does not receive these messages within a certain time frame, the ABS module sets a DTC. For information on the messages sent to the ABS module by the PSCM, refer to the Network Message Chart within Description and Operation of  ANTI-LOCK BRAKE SYSTEM (ABS) AND STABILITY CONTROL  .
