|
Parking lock actuator (EPL)
|
The parking lock actuator performs the parking lock/unlock by driving the manual shaft using the built-in motor and gears.
|
(See PARKING LOCK ACTUATOR [A71M].)
|
|
Selector lever (ECL)
|
The shift position sensor in the selector lever detects the driver’s selector lever operation and sends it to the PCM via CAN communication.
|
(See SELECTOR LEVER [A71M].)
|
|
PCM
|
Receives information from each module and determines the shift position change.
Sends a shift position change request signal to the parking lock actuator and DMCM.
|
(See PCM.)
|
|
DMCM
|
Switches the electric motor rotation direction based on the request signal from the PCM.
|
(See INVERTER.)
|
|
BCM
|
Relays CAN communication between each module for the shift-by-wire system.
|
|
|
Indicator
|
Indicates the actual shift position for the driver.
|
(See INDICATOR [A71M].)

Shift System Warning Indication/Warning Light
|
Warns the driver of a malfunction in the shift-by-wire system.
|
|
|
Shift position warning beep
|
Notifies the driver by a warning beep if the selector lever position is different than the actual shift position.
|
|
|
Selector lever not P reminder warning beep
|
Notifies the driver that the selector lever is not in the P position by a warning beep to prevent the driver from leaving the vehicle with the selector lever in a position other than the P position.

Auto P function
|
If the vehicle detects an operation by the driver intending to leave the vehicle with the shift position in a position other than P position, the vehicle switches the shift position to P position automatically.
|
(See AutoP FUNCTION [A71M (E)].)
|
|
Shift position restrictions
|
If a specific operation by the driver is detected while accelerating from a standstill or driving, the vehicle restricts the shift position switching for safety.
