Diagnostic Test

CHECK FOR AN ACTIVE DTC
1. With the scan tool, read Body Control Module (BCM) DTCs and record on the repair order.
2. Record the Environmental Data and any DTCs.
3. With the scan tool, erase DTCs.
4. Using the recorded Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
5. With the scan tool, read BCM DTCs.
  Did the DTC return?
  
  Yes
  - Go To 2
  No
  - Perform the TESTING FOR AN INTERMITTENT CONDITION procedure. Refer to TESTING FOR AN INTERMITTENT CONDITION .
CHECK THE (Q5) SUNROOF CLOSE SWITCH SENSE CIRCUIT FOR CONTINUITY TO GROUND
1. Turn the ignition off.
2. Disconnect the Sunroof Shade Motor harness connector.
3. Check for continuity between ground and the (Q5) Sunroof Close Switch Sense circuit at the Sunroof Shade Motor harness connector.
  Is there continuity between ground and the (Q5) Sunroof Close Switch Sense circuit?
  
  Yes
  - Go To 3
  No
  - Go To 4
CHECK THE (Q5) SUNROOF CLOSE SWITCH SENSE CIRCUIT FOR A SHORT TO GROUND
1. Disconnect the BCM C8/H harness connector.
2. Check for continuity between ground and the (Q5) Sunroof Close Switch Sense circuit at BCM C8/H harness connector - terminal 17.
  Is there continuity between ground and the (Q5) Sunroof Close Switch Sense circuit?
  
  Yes
  - Repair the short to ground on the (Q5) Sunroof Close Switch Sense circuit.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  No
  - Go To 5
CHECK THE (Q5) SUNROOF CLOSE SWITCH SENSE CIRCUIT FOR AN OPEN OR HIGH RESISTANCE
1. Turn the ignition off.
2. Disconnect the BCM C8/H harness connector.
3. Measure the resistance on the (Q5) Sunroof Close Switch Sense circuit between the Sunroof Shade Motor harness connector and BCM C8/H harness connector - terminal 17.
  Is the resistance above 3.0 Ohms?
  
  Yes
  - Repair the open or high resistance on the (Q5) Sunroof Close Switch Sense circuit.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  No
  - Replace the Sunroof Shade Motor in accordance with the Service Information. Refer to MOTOR, SUNROOF SHADE, REMOVAL AND INSTALLATION .
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
CHECK RELATED HARNESS CONNECTIONS
1. Disconnect all BCM harness connectors.
2. Disconnect all related in-line harness connections (if equipped).
3. Disconnect the related component harness connectors.
4. Inspect harness connectors, component connectors, and all male and female terminals for the following conditions:
  - Proper connector installation.
  - Damaged connector locks.
  - Corrosion.
  - Other signs of water intrusion.
  - Weather seal damage (if equipped).
  - Bent terminals.
  - Overheating due to a poor connection (terminal may be discolored due to excessive current draw).
  - Terminals that have been pushed back into the connector cavity.
  - Perform a terminal drag test on each connector terminal to verify proper terminal tension.
  Repair any conditions that are found.
5. Reconnect all BCM harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
6. Reconnect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
7. Reconnect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.
8. With the scan tool, erase DTCs.
9. Using the recorded Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
10. With the scan tool, read BCM DTCs.
  Did the DTC return?
  
  Yes
