Diagnostic Procedure

DOOR GLASS DIAGNOSTIC PROCEDURE

Step	Inspection		Action
1	VERIFY IF MALFUNCTION CAUSE IS OPERATION UNDER OPERATION PERMISSION CONDITION Turn the power-cut switch off (contact point: closed) and perform open/close operation. Does the power window system operate normally?	Yes	System is normal. (Tell the customer about the power-cut switch.)
1		No	Go to the next step.
2	POWER WINDOW SUBSWITCH CONNECTOR INSPECTION Switch the ignition off. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Disconnect the power window subswitch connector. Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. Is the connector normal?	Yes	Go to the next step.
2		No	Repair or replace the connector, then go to Step 4.
3	VERIFY IF MALFUNCTION CAUSE IS POWER WINDOW SUBSWITCH POWER SUPPLY CIRCUIT Connect the power window subswitch connector. Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Measure the voltage at power window subswitch terminal C (vehicle wiring harness side). Is the voltage B+?	Yes	Replace the power window subswitch, then go to the next step. (See POWER WINDOW SUBSWITCH REMOVAL/INSTALLATION .)
3		No	Inspect the P.WINDOW1 30A fuse. If the fuse is damaged: Replace the fuse. If the fuse is normal: Refer to the SYSTEM WIRING DIAGRAMS article and verify if there is a common connector between P.WINDOW1 30A fuse and power window subswitch terminal C. If there is a common connector: Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for open or short circuit to determine the malfunctioning location. Repair or replace the malfunctioning location. If there is no common connector: Repair or replace the wiring harness which has an open or short circuit. Go to the next step.
4	VERIFY IF MALFUNCTION CAUSE IS CORRECTED Does the power window system operate normally?	Yes	Troubleshooting completed. (Explain the problem to the customer.)
4		No	Verify the malfunction symptom in the symptom troubleshooting chart and perform the other applicable malfunction diagnosis.
