PUSH BUTTON START SYSTEM [(E)]

id0914007035x2


Outline

•  A push button start system has been adopted that automatically performs authorization of the remote transmitter brought into the vehicle.

Function

•  When the power switch is pressed, the push button start system performs authorization of the remote transmitter in the vehicle.
―  Power supply switching: When the remote transmitter authorization is performed, the main power is switched OFF or to ACC, or ON (READY off).
•  The guidance function displays methods of resolving issues, such as insufficient conditions for switching the main power ON (READY on) or remote transmitter authorization cannot be performed, on the multi-information display.

Operation


Remote transmitter verification

1.  When the power switch is pressed, a power switch signal (1) is input to the body control module (BCM).

2.  When the body control module (BCM) detects a power switch signal, it sends a request signal (2) using all the keyless antennas in the vehicle interior via the LF control unit.

3.  The remote transmitter receives the request signal from the interior keyless antennas, and transmits ID data (3) to the keyless receiver.

4.  When the keyless receiver receives ID data, it sends (4) the ID data to the LF control unit via serial communication. The LF control unit verifies the ID data, and if the ID data matches, it sends the verified result (5) to the body control module (BCM).

5.  The body control module (BCM) releases (6) the steering lock and at the same time switches the power supply to turn the power switch indicator light (amber) on. For details on the power supply switching, refer to the [POWER SUPPLY SWITCHING].(See POWER SUPPLY SWITCHING.)

READY on operation

•  When all of the following conditions are met, the main power switches ON (READY on) when the power switch is pressed.
READY on conditions
―  Brake pedal is depressed
―  Actual shift position is P
―  Shift position selector lever is shifted to is P position
―  Remote transmitter is within request output range of keyless antennas in vehicle interior


Guidance function

Display of main power switched ON (READY on) advice
•  Under the following conditions, the body control module (BCM) sends an advice request signal via CAN transmission to the instrument cluster.
•  When the instrument cluster receives an advice request signal, it displays the conditions which have not been met in order to start the engine in the multi-information display.

Condition

Multi-information display
Main power is switched from OFF to ON (READY off) without depressing brake pedal
Power switch is pressed with main power switched ON (READY off) and selector lever not in P position

Display of methods for resolving issues
•  Under the following conditions, the body control module (BCM) sends a warning request signal via CAN transmission to the instrument cluster to flash the KEY indicator light.
•  When the instrument cluster receives the warning request signal, it displays the method for resolving an issue in the multi-information display.
