CTA 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 CTA warning chime sounds to alert the driver that a vehicle has been detected or that there is a system fault. The CTA warning chime sounds a 0.25-second chime continuously until the request is ended. The active park assist chime sounds through the rear speakers.

The IPC receives the CTA left status, the CTA right status, side obstacle detect status-left and the side obstacle detect status-right request messages from the GWM over the HS-CAN3.

The GWM receives the CTA left status and the side obstacle detect status-left messages from the SODL over the MS-CAN.

The GWM receives the CTA right status and the side obstacle detect status-right request messages from the SODR over the MS-CAN.

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