Pedestrian Alert System

The pedestrian alert system provides an audible alert when the vehicle is moving in forward or reverse between 0-30 km/h (0-8 mph). The PACM receives all network messages required to operate the system over the HS-CAN1.

In the event of a system fault, the IPC message center displays the Pedestrian Alert Fault Service Now warning message in the message center. The IPC receives the pedestrian alert fault message from the GWM over the HS-CAN3. The GWM receives the pedestrain alert fault message from the PACM over the HS-CAN1.

Component Description

PACM

The PACM controls the pedestrian alert system and is capable of setting Diagnostic Trouble Codes (DTCs) when a fault condition is detected. The PACM requires PMI when replaced.
