MANUAL FUNCTION
Description
 Automatic drive positioner control unit controls door mirror.
 Automatic drive positioner control unit inputs changeover switch signal and perform the LH/RH control of
door mirror motor supplying electric power when changeover switch is operated.
 Automatic drive positioner control unit inputs mirror s witch signal and supplies electric power to door mirror.
 The ignition switch signal (ACC/ON) is transmitted from BCM to driver seat control unit via CAN communica-
tion and from driver seat control unit to automatic drive positioner control unit via UART communication.
Operation Conditions
If the following conditions are not satisfied, operation is not performed.
 Ignition switch: ON or ACC
 Changeover switch: Select either left or right
REVERSE INTERLOCK DOOR MIRROR SYSTEM
Description
 Select either of the door mirror faces by changeover switch, and then set mirror face downward.
 When ignition switch is ON position and A/T shift selector is in R position, TCM sends the R signal to driver
seat control unit.
 The R signal is transmitted to automatic drive positioner control unit from driver seat control unit via UART
communication.
 When the R signal is detected, automatic drive positioner control unit activated mirror motor.
Operation Conditions
If the following conditions are not satisfied, operation is not performed.
 Ignition switch: ON
