Title: DOOR / HATCH: POWER BACK DOOR SYSTEM: Power Back Door cannot be Operated Using Kick Sensor; 2024 MY RAV4 RAV4 HV [10/2023 - ] |
Power Back Door cannot be Operated Using Kick Sensor
|
DESCRIPTION
The kick door control sensor uses LIN communication and stops sensor output based on the vehicle speed, ignition switch ON (IG) or ON (ACC) signals sent from the multiplex network door ECU.
When the kick door control sensor detects a kick operation, it sends an operation signal to the multiplex network door ECU.
