Switch The Power Supply Using The Push Button Start And Start The Engine

WARNING: This page is about a different car, the 2018 Mazda CX-9. However, it is still accessible from the selected car via links, so may be relevant.

Based on the push button start signals, the start stop unit switches the power supply circuit by turning on/off the relay according to the vehicle conditions such as the position of the selector lever and depression/release of the brake pedal.
By pressing the push button start under the conditions shown in the figure, the ignition can be switched.
