Diagnostic Overview

The Message Center Displays A Blocked Sensor Message

Refer to Wiring Diagram Set 136 for schematic and connector information Electrical Diagrams.

Normal Operation and Fault Conditions

A blocked sensor message indicates there is an obstruction on the rear bumper cover that does not allow the radar from the SOD-L (Side Obstacle Detection Control Module - Left) and SOD-R (Side Obstacle Detection Control Module - Right) to penetrate.

REFER to BLIS(R) and CTA Message Display .

Pinpoint Test

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

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

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?








2. 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

1. Inspect for debris, mud, snow or ice on the rear bumper cover, 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?








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

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

2. Repair:

- corrosion (install new connector or terminals- clean module pins)
- damaged pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

3. Reconnect the SOD-L (Side Obstacle Detection Control Module - Left) connector. Make sure it seats and latches correctly.

4. Operate the system and determine if the concern is still present.

Is the concern still present?








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

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

2. Repair:

- corrosion (install new connector or terminals- clean module pins)
- damaged pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

3. Reconnect the SOD-R (Side Obstacle Detection Control Module - Right) connector. Make sure it seats and latches correctly.

4. Operate the system and determine if the concern is still present.

Is the concern still present?
