Diagnostic Procedure

DOOR GLASS DIAGNOSTIC PROCEDURE

Step	Inspection		Action
1	POWER WINDOW MAIN SWITCH 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 main switch 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.
1		No	Repair or replace the connector, then go to Step 4.
2	POWER WINDOW SUBSWITCH CONNECTOR INSPECTION 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	POWER WINDOW MAIN SWITCH INSPECTION Reconnect all the disconnected connectors. Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Measure the voltage at the following power window main switch terminals (vehicle wiring harness). (See POWER WINDOW MAIN SWITCH INSPECTION .) Terminals 1B and 1D if door glass (RF) does not operate Terminals 1G and 11 if door glass (LR) does not operate Terminals 1A and 1C if door glass (RR) does not operate Is the power window main switch normal?	Yes	Refer to the wiring diagram and verify if there is a common connector between the following terminals. Power window main switch terminal 1D and power window subswitch (RF) terminal E Power window main switch terminal 1B and power window subswitch (RF) terminal B Power window main switch terminal 11 and power window subswitch (LR) terminal E Power window main switch terminal 1G and power window subswitch (LR) terminal B Power window main switch terminal 1C and power window subswitch (RR) terminal E Power window main switch terminal 1A and power window subswitch (RR) terminal B If there is a common connector: Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for an 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.
3		No	Replace the power window main switch, then go to the next step. (See POWER WINDOW MAIN SWITCH REMOVAL/INSTALLATION .)
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.
