Push Button Ignition Switch: Notes
The push button ignition switch controls the ignition mode.
There are 2 circuits the BCM monitors from the push button ignition switch to change the ignition mode. One circuit is monitored for voltage and the other for a ground signal. When the START/STOP button is pressed, one circuit routes battery voltage to the BCM while a voltage signal from the BCM on the second circuit is routed to ground, indicating a request to change the ignition mode. Changing the ignition mode out of OFF works in conjunction with the PATS. The BCM must recognize a valid programmed key before it changes the ignition mode out of OFF. Refer to: Steering Wheel and Column Electrical Components - System Operation and Component Description
Refer to the following table for information about achieving the various ignition modes.
