Door Ajar Warning Chime

WARNING: This page is about a different car, the 2018 Ford F-550 Super Duty, 2018 Ford F-450 Super Duty, 2018 Ford F-350 Super Duty, and 2018 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

The door ajar warning chime warns that a door is ajar and sounds the chime through the front speakers. When a door becomes ajar while the ignition is in RUN with vehicle speed greater than 5 km/h (3 mph), the IPC displays the appropriate door ajar warning message and sounds a single chime tone for each door opened. The door ajar chime only sounds once for each time the door is opened, and only repeats the chime if the door is closed then reopened.

The IPC receives the door ajar status messages (driver, passenger, left rear and right rear) from the GWM over the HS-CAN3. The GWM receives the door ajar status messages (driver, passenger, left rear and right rear) from the BCM over the HS-CAN1.

When a chime request is received, the IPC sends the IPC chime request message to the ACM or the audio DSP to sound the chime.
