Manual Zoom
WARNING: This page is about a different car, the 2019 Ford F-550 Super Duty, 2019 Ford F-450 Super Duty, 2019 Ford F-350 Super Duty, and 2019 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
The manual zoom feature is generated by the rear parking aid camera and has one level of zoom. If the manual zoom feature is on and the vehicle is shifted out of reverse gear, the manual zoom feature is disabled and must be re-enabled the next time reverse gear is APIM through HS-CAN3 to the GWM, then over HS-CAN2 to the IPMB. The IPMB then sends the manual zoom request message to the CHMSL camera via the LIN circuit or the rear camera via the coaxial cable.
