Blind Spot Monitoring

Pinpoint Test D: DTC B11D6:11 Or DTC B11D6:15

Refer to Wiring Diagram Set 136, Vehicle Emergency Messaging System for schematic and connector information Electrical Diagrams.

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(R)) /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 (Side Obstacle Detection Control Module - Right) or SOD-L (Side Obstacle Detection Control Module - Left) detect a short to ground on the exterior mirror BLIS(R) (Blind Spot Information System) /CTA (Cross Traffic Alert) LED supply circuit.

- DTC B11D6:15 (Driver Display Alert LED: Circuit Short To Battery or Open)- sets when the SOD-R (Side Obstacle Detection Control Module - Right) or SOD-L (Side Obstacle Detection Control Module - Left) detect an open on the exterior mirror BLIS(R) (Blind Spot Information System) /CTA (Cross Traffic Alert) LED supply circuit.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- SOD-L (Side Obstacle Detection Control Module - Left)

- SOD-R (Side Obstacle Detection Control Module - Right)

- Exterior mirror BLIS(R) (Blind Spot Information System) /CTA (Cross Traffic Alert) LED

PINPOINT TEST D : DTC B11D6:11 OR DTC B11D6:15

NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: Failure to disconnect the battery when instructed results in false resistance readings.
