Preliminary Procedure
- Verify customer's complaint by operating power windows. Check window alignment and window mounting. Check for window frame interference or damaged switches. Check for blown fuse(s), loose or corroded connectors, or damaged wiring harness. Repair or replace components as necessary.
- If all components are okay, connect NGS tester to DLC located below instrument panel. Using NGS tester, perform DATA LINK DIAGNOSTIC TEST. If NGS tester displays CKT 914 or CKT 915=ALL MODULES NO RESPONSE/NOT EQUIPPED, see MODULE COMMUNICATIONS NETWORK article to diagnosis network concern. If NGS tester displays NO RESPONSE/NOT EQUIPPED for Driver Door Module (DDM), go to TEST A: NO COMMUNICATION WITH DDM under SYSTEM TESTING. If NGS tester displays NO RESPONSE/NOT EQUIPPED for Steering Column Ignition Lighting Control (SCIL) module, go to TEST B: NO COMMUNICATION WITH SCIL MODULE under SYSTEM TESTING.
- If NGS tester displays SYSTEM PASSED for DDM, retrieve and record continuous DTCs using NGS tester. Erase continuous DTCs. Perform DDM self-test diagnostics using NGS tester. If DTC B1549 is retrieved, go to DTC B1549: MASTER WINDOW SWITCH SHORTED TO BATTERY VOLTAGE under DIAGNOSTIC TESTS. If any other DDM DTC is retrieved, see DRIVER DOOR MODULE (DDM) DTC DEFINITIONS to continue diagnosis. If no DTCs are retrieved, perform appropriate test under SYSTEM TESTING .
- If NGS tester displays SYSTEM PASSED for SCIL module, retrieve and record continuous DTCs using NGS tester. Erase continuous DTCs. Perform SCIL module self-test diagnostics using NGS tester. If any SCIL module DTC is retrieved, see STEERING COLUMN/IGNITION/LIGHTING (SCIL) MODULE DTC DEFINITIONS table to continue diagnosis. If no DTCs are retrieved, perform appropriate test under SYSTEM TESTING.
