Overview
Note. The SOD-L and SOD-R communicate with the BCM over the extended MS-CAN. The BCM sends requests for the warning messages to the IPC and the illumination requests of the exterior mirror BLIS®/CTA LEDs to the DDM and PDM.
BLIS® is a feature that aids the driver in assessing whether another vehicle is within an area (blind zone) to either side of the vehicle, extending rearward to approximately 3.05 m (10 ft) beyond the rear bumper, while driving on roads and freeways. The system is not designed to prevent contact with other vehicles or objects.
The CTA system assists the driver in backing out of a parking space.
When a MyKey® restricted key is in use, the BLIS® and CTA system cannot be turned off in the IPC.
If the vehicle is towing a trailer, the BLIS® and CTA automatically turns off, if the trailer tow bar is equipped from the factory.
Diagnostic Overview
Diagnostics in this information assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in SERVICE INFORMATION for information about these practices.
Normal Operation and Fault Conditions
Refer to System Operation - BLIS® .
Diagnostics in this information assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in SERVICE INFORMATION for information about these practices.
Refer to System Operation - CTA SYSTEM .
Refer to System Operation - EXTERIOR MIRROR INDICATION .
Refer to System Operation - SYSTEM DIAGRAM .
Refer to System Operation - NETWORK MESSAGE CHART .
Note. The CTA system is turned off for one key cycle only when using the message center switches. Permanently disabling the CTA system is carried out in the Integrated Diagnostic System (IDS) programmable parameters menu.
The SOD-L and SOD-R are identical modules except the SOD-R uses an address ground pin for configuration. The address ground is necessary so the CTA system can decipher between the right and the left module.

Refer to SYSTEM WIRING DIAGRAMS - Vehicle Emergency Messaging System for additional information.
On each ignition cycle, the SOD-L and SOD-R run a self-diagnostic check during which the exterior mirror BLIS®/CTA LEDs illuminate for 3 seconds then turn off indicating the system is operational. If a DTC fault is present, a system fault message is observed in the message center.
