Door Open Linked Operation Cannot Be Canceled

SEAT: REAR POWER SEAT CONTROL SYSTEM: Door Open Linked Operation cannot be Canceled
- Door Open Linked Operation cannot be Canceled

DESCRIPTION

When the rear seat memory switch's C switch is pressed, a C switch signal is sent from the rear door ECU to the rear power seat switch through CAN communication. Then the rear power seat switch sends the C switch signal to the position control ECU through the LIN line. When the position control ECU receives the C switch signal, the door open linked return operation is stopped.
