Parking Aid Control Module (PACM): Notes
The Parking Aid Control Module (PACM) located behind the Instrument Panel (IP).
The PACM has two connectors which provide power, ground, High Speed (HS) Controller Area Network (CAN) chassis systems bus connections, front and rear parking aid sensors and front and rear park assist sensors.
The HS CAN chassis system bus connections provide for the receipt of the following information from the systems:
- Anti-lock Brake System (ABS) control module - Road speed signal.
- Transmission Control Module (TCM) - Reverse (R) and Drive (D) gear engaged signal.
The PACM also outputs messages on the HS CAN chassis systems bus.
The Body Control Module/Gateway Module (BCM/GWM) assembly processes these messages and passes them to HS CAN comfort systems bus
If the vehicle is equipped with the following system, the HS CAN comfort systems bus messages are sent the Audio Head Unit (AHU):
- InControl™ Touch infotainment system.
If the vehicle is equipped with the following system, the HS CAN comfort systems bus messages are sent the Infotainment Master Controller (IMC):
- InControl™ Touch Pro infotainment system.
