Stop/Start Override Function

This Axxess Technologies interface automatically disengages the factory STOP/START engine system on compatible Ford and Chrysler vehicles from 2015 onward. It restores driver control over the feature without permanent modification to the vehicle electronics. The unit works with both factory and aftermarket radio installations.

Sustained Operation Behaviour

Once configured via the Axxess Updater software, the interface continuously suppresses the STOP/START function each time the vehicle is started. The original dashboard button remains fully functional and can reactivate the system instantly when pressed. No further user input is required during daily driving cycles.

Installation and Electrical Load

The device connects through a simple four-wire harness at the radio location, drawing minimal current from the vehicle's electrical system. It produces no audible noise and generates negligible heat during operation. The compact wire harness design allows it to be tucked neatly behind the dashboard without affecting other electronics.

Questions about this item

Does the AX-SSO draw enough current to affect battery drain during long drives?

The interface uses a simple 4-wire connection at the radio location and only activates when the STOP/START system engages, so its power draw is minimal and will not affect battery performance during daily driving.

What existing wiring or modules in my 2017 Chrysler Pacifica must be present for the AX-SSO to function?

The unit connects at the radio location using four wires and requires the factory STOP/START button and vehicle CAN communication to be intact; no additional modules or aftermarket harnesses are needed.

Will the AX-SSO interfere with the factory stop/start system on my 2015 Ford F-150 if I later reinstall the original radio?

No, the interface works with both factory and aftermarket radios, and the original STOP/START button remains fully functional to re-enable the feature at any time.
