Flow of Diagnosis

1. Verify the customer's concern by operating the electronic door lock control system to duplicate the concern.
2. Inspect to determine if one of the following mechanical or electrical concerns apply:

VISUAL INSPECTION CHART

Mechanical:
^ Binding Latches
^ Damaged Door Lock Cylinders
^ Damaged Luggage Compartment Door Lock Cylinder

Electrical
^ Open Fuses:
^ I/P Fuse Panel:
- No. 8 (5 A) Fuse
- No. 20 (5 A) Fuse
- No. 12 (5 A) Fuse
- No. 26 (15 A) Fuse
- No. 23 (5 A) Fuse
^ Loose Connectors
^ Corroded Connectors
^ Relays
^ Switches

3. If inspection reveals an obvious concern that is readily serviced, correct the concern before continuing with Inspection and Verification.
4. If the concern remains after the inspection connect the Rotunda New Generation Star (NGS) Tester 418-F048 (007-00500) or equivalent to the Data Link Connector (DLC) located beneath the instrument panel to perform the Data Link Diagnostics Test. If the NGS responds with NO RESP/NOT EQUIP for the Generic Electronic Module (GEM), go to Pinpoint Test A. A: No Communication With Generic Electronic Module If the NGS responds with NO RESP/NOT EQUIP for the Remote Anti-Theft Personality (RAP) Module, go to Pinpoint Test B. B: No Communication With Anti-Theft Personality (RAP) Module If the Data Link Diagnostic test is passed for the GEM or the RAP Module, retrieve continuous DTCs and execute self test diagnostics.
5. If self test is passed and no DTCs are retrieved, go to the Symptom Chart to continue diagnostics.
6. If DTCs are retrieved for the generic electronic module, go to the GEM Diagnostic Trouble Code (DTC) index to continue diagnostics If DTCs are retrieved for the remote anti-theft personality module, go to the RAP Module Diagnostic Trouble Code (DTC) Index to continue diagnostics.
7. If the GEM cannot be accessed by the NGS tester, go to Pinpoint Test A. A: No Communication With Generic Electronic Module If the RAP Module cannot be accessed by the New Generation Star (NGS) Tester, go to Pinpoint Test B. B: No Communication With Anti-Theft Personality (RAP) Module

Rotunda Service Bay Diagnostic System (SBDS(R)) 418-F001 (001-00001) may also be used to diagnose this system.
