Retrieving Codes
NOTE:
A New Generation Star (NGS) tester is required for testing the power window system.
Before beginning any testing, retrieve any existing Diagnostic Trouble Codes (DTCs). See ON-DEMAND SELF-TEST in this article. Make any repairs that may be indicated. See appropriate PINPOINT TESTS. If symptoms remain, or if no DTCs exist, refer to the SYMPTOM-TO-PINPOINT TEST MENU , then go to appropriate PINPOINT TEST.
