Parking Aid Control Module (PACM)
The Parking Aid Control Module (PACM) is located behind the instrument panel.
The PACM has two connectors which provide power, ground, High Speed (HS) Controller Area Network (CAN) chassis bus connections, front and rear parking aid sensors and front and rear park assist sensors.
The HS CAN chassis 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 bus.
The Body Control Module/Gateway Module (BCM/GWM) assembly processes these messages and passes them to HS CAN comfort bus.
If the vehicle is fitted with the following system, the HS CAN comfort bus messages are sent to the Audio Head Unit (AHU):
- InControl™ Touch system.
If the vehicle is fitted with the following system, the HS CAN comfort bus messages are sent to the Infotainment Master Controller (IMC):
- InControl™ Touch Pro system.
Vehicles fitted with InControl™ Touch System
The AHU will process the HS CAN comfort bus messages received by emitting the applicable warning tone to the front or rear audio speakers when an object is detected by the front or rear parking aid and park assist sensors.
A warning tone can also be emitted to alert the driver to a fault in the parking aid or park assist systems.
