Blind Spot Monitoring

Pinpoint Test D: DTC B11D6:11 Or DTC B11D6:15 (LED MAY ALWAYS BE ON)

Refer to Wiring Diagram Set 136 (Fusion/Milan/MKZ, Fusion Hybrid, Milan Hybrid, MKZ Hybrid), Vehicle Emergency Messaging System for schematic and connector information. Diagrams By Number

Normal Operation

On each ignition cycle, the Side Obstacle Detection Control Module - Right (SOD-R) and Side Obstacle Detection Control Module - Left (SOD-L) run a self-diagnostic check during which the exterior mirror Blind Spot Information System (BLIS(TM))/Cross Traffic Alert (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 displayed in the message center.

- DTC B11D6:11 (Driver Display Alert LED: Circuit Short To Ground) - sets when the SOD-R or SOD-L detect a short to ground on the exterior mirror BLIS(TM)/ CTA LED supply circuit.
- DTC B11D6:15 (Driver Display Alert LED: Circuit Short To Battery or open) - sets when the SOD-R or SOD-L detect a short to battery voltage or an open on the exterior mirror BLIS(TM)/ CTA LED supply circuit.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors
- SOD-L
- SOD-R
- Exterior mirror BLIS(TM)/ CTA LED

PINPOINT TEST D: DTC B11D6:11 OR DTC B11D6:15 (LED MAY ALWAYS BE ON)
