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.
Warning Method Of RPAS
If RPAS sensor detects the obstacle, the acoustic device makes warning sound and the display module (Cluster) indicates each warning level as like followings.
RPAS sensor sends the distance data to BCM through LIN communication and BCM received the distance data from each sensor.
BCM has the responsibility of the acoustic function.
BCM has the responsibility of the gateway function that BCM sends the warning data to Cluster as like below timing diagram.
When change from a warning area to the different zone, after finishing one cycle of warning output, the next warning sound has to start for different zone necessarily.
