Diagnostic Routine A
Diagnostic Overview
The Blind Spot Information System (BLIS) Is Inoperative Or Does Not Operate Correctly
Normal Operation and Fault Conditions
REFER to Blind Spot Information System (BLIS) Side And Rear Vision.
Pinpoint Test
1. CHECK THE BLIS(R) /CTA (Cross Traffic Alert) LEDs (Light-emitting Diodes) OPERATION
1. Carry out the diagnostic system check.
- Start the engine.
- Observe the left and right exterior mirror BLIS(R) / CTA (Cross Traffic Alert) LEDs (Light-emitting Diodes).
Do the left and right BLIS(R) / CTA (Cross Traffic Alert) LEDs (Light-emitting Diodes) illuminate and turn off after 3 seconds?
2. VERIFY THE BLIS(R) OPERATION
1. Check the BLIS(R) to verify the customer's concern.
Does the BLIS(R) operate correctly?
3. CHECK FOR SOD-L (Side Obstacle Detection Control Module - Left) AND SOD-R (Side Obstacle Detection Control Module - Right) OBSTRUCTIONS
1. Check the lower rear side bumper cover for a build up of mud, bumper stickers or any obstruction.
Are any obstructions present?
4. CHECK FOR DAMAGE TO THE LOWER REAR SIDE BUMPER COVER, THE SOD-L (Side Obstacle Detection Control Module - Left) AND SOD-R (Side Obstacle Detection Control Module - Right) MOUNTING BRACKETS
1. Check the lower rear side bumper cover, the SOD-L (Side Obstacle Detection Control Module - Left) and SOD-R (Side Obstacle Detection Control Module - Right) mounting brackets for damage.
Is any damage present?
5. VERIFY THE SOD-L (Side Obstacle Detection Control Module - Left) AND SOD-R (Side Obstacle Detection Control Module - Right) PASS THE NETWORK TEST
1. Using a scan tool, perform a network test.
Do the SOD-L (Side Obstacle Detection Control Module - Left) and SOD-R (Side Obstacle Detection Control Module - Right) pass the network test?
6. VERIFY THE BLIS(R) CONFIGURATION
NOTE: BLIS(R) must be enabled in both the SOD-L (Side Obstacle Detection Control Module - Left) and the SOD-R (Side Obstacle Detection Control Module - Right) or a fault condition occurs.
1. Using a scan tool, view programmable parameters.
2. Verify the BLIS(R) is enabled in the SOD-L (Side Obstacle Detection Control Module - Left) and SOD-R (Side Obstacle Detection Control Module - Right).
Is BLIS(R) enabled?
7. CHECK THE DTCs (Diagnostic Trouble Codes) FROM THE SOD-L (Side Obstacle Detection Control Module - Left) AND SOD-R (Side Obstacle Detection Control Module - Right) SELF-TESTS
1. Using a scan tool, perform the SOD-L (Side Obstacle Detection Control Module - Left) and SOD-R (Side Obstacle Detection Control Module - Right) DTCs (Diagnostic Trouble Codes) self-tests.
Are any DTCs (Diagnostic Trouble Codes) recorded?
8. CHECK FOR VEHICLE SPEED SIGNAL DTCs (Diagnostic Trouble Codes)
1. Using a scan tool, perform the BCM (Body Control Module) self-test.
Are any vehicle speed related DTCs (Diagnostic Trouble Codes) present?
9. 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?
10. 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?
