Install push button start

[silvermitsu10]

Maybe I'm too far off base but I would think the easiest option would be to remove a system from a wrecked Maverick.

I kinda thought this may be an option as well. Just haven’t really dug in to see how deeply integrated it is and what all would have to be changed. What modules does it affect and how so. That’s a bit of research that really needs to be done to go this route and I don’t really even know where to start to figure all that out.

I know from adding a factory ambient light circuit to a 2024 XLT that the BCM of the Lariat has a different part# and pinout to the 2022-2024 XL, XLT. IIRC the Ford parts catalog listed the Lariat as w/ keyless start.

If the option is to install the whole system on my $27k xl vs trading up to a $40k plus lariat when this and heated seats are the only things from the lariat I want… yes.

If you do decide to go this route let me know how it goes please. The only thing I’m worried about is how to get around the steering wheel lock on the factory ignition switch. If I still have to use an oem key then that kind of defeats the purpose.

Yes that’s what I had to do on my 3 previous cars. Still turn the key to unlock the steering. Havent checked to see if the Mav is the same. It’s more of a kill switch than a push to start. Each car had the button hidden in plain sight:
Extra factory fog light button.
Extra Aux light switch.
Extra factory climate control button.

The Maverick does not have a steering wheel lock.
Steering wheel locks started disappearing about 15 years ago. Roughly coincided with the emergence of electric power steering and pushbutton ignition switches, but by no means a perfect correlation. FMVSS 114 is the American standard for theft protection.

211-05 Steering Wheel and Column Electrical Components Description and Operation

System Diagram - Conventional Ignition Switch

Ignition Switch System
The BCM controls the ignition modes, including OFF, ACC, ON and START.
This allows some systems to be activated without starting the vehicle.
The BCM provides voltage at all times to the ignition switch. Depending on the ignition switch position, voltage may be routed to one or two of the ignition switch input circuits back to the BCM.

OFF
When the ignition switch is in the OFF position, the switch is open, preventing any voltage signals from reaching the BCM.
When the BCM does not detect voltage from any of the ignition mode-designated circuits, the BCM interprets this as the ignition off mode.
The BCM communicates the ignition mode to the other modules by sending an ignition status message over the CAN and does not energize any relays to prevent voltage from being distributed to the various electrical systems.

ACC
When the ignition switch is in the ACC position, the switch routes voltage through the ACC-designated circuit to the BCM.
The BCM interprets this as the ignition accessory mode.
The BCM communicates the ignition mode to the other modules by sending an ignition status message over the CAN and energizes the accessory designated relays and provides power to some electrical systems.

ON
When the ignition switch is in the ON position, the switch routes voltage through the ACC-designated and ON-designated circuits to the BCM.
The BCM interprets this as the ignition on mode.
The BCM communicates the ignition mode to the other modules by sending an ignition status message over the CAN and activates the internal run/start relay, providing ignition power to the various vehicle systems and modules.

START
When the ignition switch is placed in the START position, the switch routes voltage through the ON-designated and START-designated circuits to the BCM.
The BCM interprets this as the ignition start mode and communicates the ignition mode to the other modules by sending an ignition status message over the CAN.
Additionally, the ignition switch routes voltage to the PCM indicating a request to start the vehicle.
The START-designated circuit is only used for vehicle starting.

Ignition Key Inhibit
The ignition key inhibit feature prevents the ignition lock cylinder from being rotated to the OFF/LOCK position when the vehicle is not in PARK.
The key release interlock actuator receives battery voltage at all times. The ground control circuit for the key release interlock actuator is controlled by the BCM.
The BCM controls the ground by means of a Field Effect Transistor (FET). The BCM enables the path to ground when it detects the vehicle is not in PARK based on messages received over the CAN .
When the selector lever is in PARK, the key release interlock actuator deactivates and allows the ignition lock cylinder to be turned to the OFF/LOCK position to remove the key.


System Diagram - Push Button Ignition Switch

Push Button Ignition Switch
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.

Ignition Mode LED Indicator (If Equipped)
The ignition mode LED indicates the ignition mode of the vehicle. The BCM controls the voltage to the ignition mode LED indicator.

OFF
The BCM controls the relays providing voltage to the vehicle electrical systems.
When the ignition is in the ON mode, a single press and release of the START/STOP button (without applying the brake pedal) changes the ignition to the OFF mode.
No programmed key is required to change the ignition to the OFF mode when the vehicle is running.
If the vehicle is in motion, a momentary press of the START/STOP button does not shut the vehicle off.
If the vehicle is moving at a speed greater than 15 km/h (9 mph), the START/STOP button must be pressed and held for longer than one second (or pressed 3 times within 2 seconds) to turn the ignition off.
When the BCM changes the ignition mode to OFF, it communicates the ignition mode to the other modules by sending an ignition status message over the CAN.

ON
When the ignition is in the ON mode, the BCM activates the run/start relay to provide voltage to the vehicle electrical systems and communicates the ignition mode to the other modules by sending an ignition status message over the CAN.
When the vehicle enters ON mode, multiple indicators in the IPC prove out and the IPC displays the gear selection and the vehicle mileage.

START
If the brake pedal is applied when the START/STOP button is pressed, and a valid key is detected within the vehicle, the vehicle temporarily goes into the START mode.
In addition to activating the run/start relay, the BCM communicates the ignition mode to the other modules by sending an ignition status message over the CAN.

After the ignition has completed the vehicle start sequence, the ignition mode returns to ON and the ignition mode indicator in the ignition switch illuminates steadily.

The engine can be started from any ignition mode.

Guys I been waiting for this since day one, whomever does this 1st and post a video tutorial not only gonna be mega praised it also have the pizza and a six pack, I'd take care of that.
