Parallel Parking: Notes
| ITEM | DESCRIPTION |
|---|---|
| 1 | Parallel parking sequence |
When parallel parking is selected, the system automatically searches for a space that is big enough to maneuver into using the park assist sensors.
When a parking space has been identified, the park assist sensors inform the Parking Aid Control Module (PACM) so that the PACM calculates the parking trajectory. The PACM then sends a High Speed (HS) Controller Area Network (CAN) chassis systems bus message via the Body Control Module/Gateway Module (BCM/GWM) assembly to the Instrument Cluster (IC). A message will then be displayed in the message center and a audio warning from the speakers will inform the driver of this.
The message center will then instruct the driver to drive forward until the instructions on the message center tell you to stop. Once the PACM has established that vehicle has stopped, The PACM will then send information to the message center, for the driver to let go off the steering wheel.
The PACM will then inform the IC to instruct the driver to select Reverse (R) gear. Once driver has followed these instructions, information is then sent to the Transmission Control Module (TCM) and Power Steering Control Module (PSCM) and back to the PACM for parallel parking sequence to begin.
During the parallel parking sequence, the PACM, PSCM, and IC will continue to communicate with each other. The PACM will send out information that it receives, and send back to the message center for the driver to follow instructions.
