Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Active Park Assist
When the active park assist system is enabled, the Parking Aid Module (PAM) will utilize ultrasonic sensors to locate and measure a parking space. Once a parking space is identified by the system and accepted by the driver, the PAM will send steering command messages to the PSCM over the HS-CAN bus. The PSCM will utilize steering angle information and wheel speed sensor information (wheel speed is transmitted by the ABS module over the HS-CAN bus) to actuate the steering system as requested by the PAM .
Any driver inputs via the steering wheel will deactivate the active park assist system. Also, the presence of certain DTCs in the PSCM , PAM and/or ABS module will disable the system or keep the system from being activated. Refer to ACTIVE PARK ASSIST for additional information on the active park assist system.
