Blind Spot Monitoring

Pinpoint Test F: The Message Center Displays A Blocked Sensor Message

Normal Operation

A blocked sensor message indicates there is an obstruction on the rear bumper cover that does not allow the radar from the Side Obstacle Detection Control Module - Right (SOD-R) and Side Obstacle Detection Control Module - Left (SOD-L) to penetrate. Wet mud, thick mud, heavy rain, heavy road splash from rain, snow or ice are possible obstructions.

If the system is in a blocked state, the radar misses targets, but still counts them. After approximately 4 counted/missed targets, the system sends a BLIND SPOT NOT AVAILABLE SENSOR BLOCKED and/or CROSS TRAFFIC NOT AVAILABLE SENSOR BLOCKED message in the message center is displayed.

This pinpoint test is intended to diagnose the following:

- Dirt, ice, or snow covered rear bumper sides

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

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

PINPOINT TEST F : THE MESSAGE CENTER DISPLAYS A BLOCKED SENSOR MESSAGE

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

F1 INSPECT THE REAR BUMPER COVER AND THE SOD-L (Side Obstacle Detection Control Module - Left) OR SOD-R (Side Obstacle Detection Control Module - Right) BRACKET FOR DAMAGE

- Inspect for damage on the rear bumper cover and SOD-L (Side Obstacle Detection Control Module - Left) or the SOD-R (Side Obstacle Detection Control Module - Right) bracket.

Is the rear bumper cover, SOD-L (Side Obstacle Detection Control Module - Left) or the SOD-R (Side Obstacle Detection Control Module - Right) bracket damaged?

Yes
For the rear bumper cover, REPAIR or REPLACE the rear bumper cover as necessary.

For the SOD-L (Side Obstacle Detection Control Module - Left) or the SOD-R (Side Obstacle Detection Control Module - Right) bracket,
REPAIR or REPLACE the SOD-L (Side Obstacle Detection Control Module - Left) or the SOD-R (Side Obstacle Detection Control Module - Right) bracket. REFER to Side Obstacle Detection (SOD) Module . TEST the system for normal operation.

No
GO to F2.

F2 INSPECT THE SOD-R (Side Obstacle Detection Control Module - Right) AND SOD-L (Side Obstacle Detection Control Module - Left) FOR DEBRIS, MUD, SNOW OR ICE

- Inspect for debris, mud, snow or ice on the rear bumper cover and SOD-R (Side Obstacle Detection Control Module - Right) and SOD-L (Side Obstacle Detection Control Module - Left) module housing.

Is the rear bumper cover and radar unit obstructed or blocked due to the concerns above?

Yes
REMOVE and CLEAN the rear bumper cover and module as necessary. Once the vehicle is cleaned, complete one key cycle and test drive the vehicle. The blocked module needs to detect an unblocked situation or 2 good detected vehicles or targets before clearing. TEST the system for normal operation.

No
For an inoperative SOD-L (Side Obstacle Detection Control Module - Left), GO to F3.

For an inoperative SOD-R (Side Obstacle Detection Control Module - Right), GO to F4.

F3 CHECK FOR CORRECT SOD-L (Side Obstacle Detection Control Module - Left) OPERATION

- Disconnect the SOD-L (Side Obstacle Detection Control Module - Left) connector.

- Check for:
- corrosion

- damaged pins

- pushed-out pins


- Connect the SOD-L (Side Obstacle Detection Control Module - Left) connector and make sure it seats correctly.

- Operate the system and verify the concern is still present.

Is the concern still present?

Yes
INSTALL a new SOD-L (Side Obstacle Detection Control Module - Left). REFER to Side Obstacle Detection (SOD) Module . TEST the system for normal operation.

No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.

F4 CHECK FOR CORRECT SOD-R (Side Obstacle Detection Control Module - Right) OPERATION

- Disconnect the SOD-R (Side Obstacle Detection Control Module - Right) connector.

- Check for:
- corrosion

- damaged pins

- pushed-out pins


- Connect the SOD-R (Side Obstacle Detection Control Module - Right) connector and make sure it seats correctly.

- Operate the system and verify the concern is still present.

Is the concern still present?

Yes
INSTALL a new SOD-R (Side Obstacle Detection Control Module - Right). REFER to Side Obstacle Detection (SOD) Module . TEST the system for normal operation.

No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
