Pinpoint Test

CHECK THE BLIS® / CTA LEDs OPERATION
1. Carry out the diagnostic system check.
  - Start the engine.
  - Observe the left and right exterior mirror BLIS® / CTA LEDs .
Do the left and right BLIS® / CTA LEDs illuminate and turn off after 3 seconds?
- Yes: GO to 2 .
- No: REFER to Diagnostic Routine D: B11D6:11 Or B11D6:15 .
VERIFY THE CTA SYSTEM OPERATION
NOTE: The CTA system only operates in reverse (R) while backing out of a front-in parking space.
1. Test the CTA system to verify the customer's concern.
Does the CTA system operate correctly?
- Yes: The fault may have been caused by an intermittent condition such as poor weather conditions or customer's perception of how the CTA system operates. REFER to the Owner's Literature.
- No: GO to 3 .
CHECK FOR SOD-L AND SOD-R OBSTRUCTIONS
1. Check the lower rear side bumper cover and lower rear bumper cover splash shield for a build up of mud, bumper stickers or any obstruction.
Are any obstructions present?
- Yes: CLEAN and REMOVE all obstructions from the lower rear side bumper cover and lower rear bumper cover splash shield.
- No: GO to 4 .
CHECK FOR DAMAGE TO THE LOWER REAR SIDE BUMPER COVER, THE SOD-L AND SOD-R MOUNTING BRACKETS
1. Check the lower rear side bumper cover, the SOD-L and SOD-R mounting brackets for damage.
Is any damage present?
- Yes: For the rear bumper cover, REPAIR or REPLACE the rear bumper cover as necessary. REFER to BUMPER COVER - REAR .
  For the SOD-L bracket, REPAIR or REPLACE the SOD-L bracket. REFER to Side Obstacle Detection (SOD) Module .
  
  For the SOD-R bracket, REPAIR or REPLACE the SOD-R bracket. REFER to Side Obstacle Detection (SOD) Module .
- No: GO to 5 .
VERIFY THE SOD-L AND SOD-R PASS THE NETWORK TEST
1. Using a scan tool, perform a network test.
Do the SOD-L and SOD-R pass the network test?
- Yes: GO to 6 .
- No:
  For SOD-L , REFER to DIAGNOSTIC ROUTINE V : The Side Obstacle Detection Control Module - Left (SOD-L) Does Not Respond To The Scan Tool.
  
  For SOD-R , REFER to Diagnostic Routine E : The SOD-R Does Not Respond To The Scan Tool Or Cannot Be Configured.
VERIFY THE CTA SYSTEM CONFIGURATION
NOTE: The CTA must be enabled in both the SOD-L and the SOD-R .
1. Using a scan tool, view programmable parameters.
2. Verify the CTA system is enabled in the SOD-L and SOD-R .
Is the CTA system enabled?
- Yes: GO to 7 .
- No: ENABLE the CTA system in the SOD-L and SOD-R using the scan tool programmable parameters menu.
CHECK FOR DTCs IN THE SOD-L AND SOD-R
1. Using a scan tool, perform the SOD-L and SOD-R DTCs self-tests.
Are any DTCs recorded?
- Yes: REFER to DTC Chart: Side Obstacle Detection Module - Left (SOD-L) and Side Obstacle Detection Module - Right (SOD-R) .
- No: GO to 8 .
CHECK THE DTCs FROM THE PAM SELF-TEST
1. Using a scan tool, perform the PAM DTCs self-test.
Are any DTCs recorded?
- Yes: REFER to DTC CHART: PARKING AID MODULE (PAM) .
- No: GO to 9 .
CHECK FOR VEHICLE SPEED SIGNAL OR PRNDL RELATED DTCs
1. Using a scan tool, perform the BCM self-test.
Are any vehicle speed or PRNDL related DTCs present?
- Yes: REFER to DTC CHART: BODY CONTROL MODULE (BCM) .
- No: For an inoperative SOD-L , GO to 10 .
  For an inoperative SOD-R , GO to 11.
CHECK FOR CORRECT SOD-L OPERATION
1. Disconnect and inspect the SOD-L 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 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?
- Yes: CHECK OASIS for any applicable TSBs . If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new SOD-L . REFER to Side Obstacle Detection (SOD) Module .
- No: The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
CHECK FOR CORRECT SOD-R OPERATION
1. Disconnect and inspect the SOD-R 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 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?
- Yes: CHECK OASIS for any applicable TSBs . If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new SOD-R . REFER to Side Obstacle Detection (SOD) Module .
- No: The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
