CHECK PUSH-BUTTON START FUNCTION

(a) Check the push-button start function:

(1) Get into the vehicle while carrying the electrical key transmitter sub-assembly with the engine switch off. With the shift lever in P, check that the key indicator display is displayed when the brake pedal is depressed. Check that the engine starts when the engine switch is pressed after the key indicator display is displayed on the multi-information display.

(2) While carrying the electrical key transmitter sub-assembly, check that the power source mode changes in the following order when the engine switch is pressed with the brake pedal released: off → on (ACC) → on (IG) → off.

HINT:

If the engine switch is pressed with the engine switch on (IG) and the shift lever not in P, the power source mode will not change to off, but to on (ACC).

(3) With the shift lever in P, check that the steering lock operates when a door is opened.

HINT:

When the engine switch is pressed after the vehicle is stopped, the engine will stop and all power will turn off. However, if the shift lever is not in P when the engine switch is pressed with the vehicle stopped, the power source mode will not change to off, but to on (ACC).

(4) Check the push-button start function operation range for the front side. Place the electrical key transmitter sub-assembly at either inspection point so that it is facing the direction shown in the illustration, and then check that the engine can be started.

NOTICE:

Even if the electrical key transmitter sub-assembly is in a vehicle interior detection area, it may not be properly detected if it is on the instrument panel, in the glove box or on the floor.

HINT:

  • Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the No. 1 indoor electrical key antenna assembly (front floor).

(5) Check the push-button start function operation range for the rear side. Place the electrical key transmitter sub-assembly at either inspection point so that it is facing the direction shown in the illustration, and then check that the engine can be started.

NOTICE:

Even if the electrical key transmitter sub-assembly is in a vehicle interior detection area, it may not be properly detected if it is on the instrument panel, in the glove box or on the floor.

HINT:

  • Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the center of the No. 1 indoor electrical key antenna assembly (rear floor).
