Power Back Door cannot be Operated Using Kick Sensor |
DESCRIPTION
The kick door control sensor receives vehicle speed, IG and ACC signals from the main body ECU (multiplex network body ECU) via LIN communication and uses the information to stop sensor oscillation.
When the kick door control sensor detects a kick operation, it sends an operation signal to the multiplex network door ECU.
