INSPECTION & VERIFICATION

Verify customer concern by operating windows to duplicate condition. Visually inspect components. If inspection reveals an obvious concern which can be easily serviced, correct malfunction before continuing inspection and verification.

COMPONENT TESTING

Note. In wiring diagram, single switch connectors are labeled as C600, C601, C709, C711, C809, and C811. In single switch test, switch terminals are referred to as connector C1 and C2. Identification has been changed for test references only.

SELF-DIAGNOSTICS

The power windows utilize a self-diagnostic system which may store a Diagnostic Trouble Code (DTC) if a problem exists in the system. DTCs may be retrieved using NGS tester and Data Link Connector (DLC) for diagnosis of system. Before performing any testing, a preliminary procedure should be performed. See PRELIMINARY PROCEDURE .
