CIRCUIT OPERATION

When you operate each power window switch for front or rear passengers (incorporated in the power window main switch), the corresponding power window motor operates, opening or closing each power window.

TECHNICAL DESCRIPTION (COMMENT)

If the corresponding power window opens and closes normally when each power window sub-switch is operated, the power window main switch may be defective.

TROUBLESHOOTING HINT
- The power window main switch may be defective
- The front power window sub switch may be defective
- The rear power window sub switches may be defective
- The ETACS-ECU may be defective
- The wiring harness or connectors may have loose, corroded, or damaged terminals, or terminals pushed back in the connector

DIAGNOSTIC PROCEDURE

STEP 1.Check the power window main switch.

Check that the driver's power window works by means of the power window main switch.

Q: Is the check result normal?

YES : Go to Step 2.

NO : Refer to inspection procedure 2 "Driver's power window does not work by means of the power window main switch." Inspection Procedure 2

STEP 2.Check the power window sub switch.

Check that each power window works by means of the respective power window sub switch when the power window lock switch is turned off.

Q: Is the check result normal?

YES : Go to Step 3.

NO : Refer to inspection procedure 3 "Relevant power window(s) do not work by means of the front and rear passenger's power window sub switches." Inspection Procedure 3

STEP 3.Determine a trouble spot.

Q: Which power window does not work?

Front passenger's door : Go to Step 4.
Rear right door : Go to Step 7.
Rear left door : Go to Step 10.

STEP 4.Check power window main switch connector E-15 and front power window sub switch connector E-09 for loose, corroded or damaged terminals, or terminals pushed back in the connector.

Q: Are front power window main switch connector E-15 and front power window sub switch connector E-09 in good condition?

YES : Go to Step 5.

NO : Repair or replace the damaged component(s). Refer to General (Electrical), Harness Connector Inspection.When the front power window sub switch (RH) is operated, the front power window (RH) should raise and lower normally.

STEP 5.Check the power window main switch for continuity.

1. Remove the power window main switch. Refer to Door Glass and Regulator.






2. Check continuity when the power window main switch is operated to "UP" or "DOWN" position.






NOTE: Set the window lock switch to UNLOCK position.

Q: Is the power window main switch normal?

YES : Go to Step 6.

NO : Replace the power window main switch. Verify that the power window works normally.

STEP 6.Check the wiring harness between power window main switch connector E-15 (terminals 12 and 14) and front power window sub switch connector E-09 (terminals 8 and 5).

NOTE: Also check intermediate connectors C-114 and C-125.If intermediate connectors C-114 or C-125 is damaged, repair or replace the damaged component(s) as described in General (Electrical), Harness Connector Inspection.

Q: Is the wiring harness between power window main switch connector E-15 (terminals 12 and 14) and front power window sub switch connector E-09 (terminals 8 and 5) in good condition?

YES : Replace the power window main switch. When the front power window sub switch (RH) is operated, the front power window (RH) should raise and lower normally.

NO : The wiring harness may be damaged or the connector(s) may have loose, corroded or damaged terminals, or terminals pushed back in the connector. Repair the wiring harness as necessary. When the front power window sub switch (RH) is operated, the front power window (RH) should raise and lower normally.

STEP 7.Check power window main switch connector E-15 and rear power window sub switch (RH) connector E-22 for loose, corroded or damaged terminals, or terminals pushed back in the connector.

Q: Are front power window main switch connector E-15 and rear power window sub switch (RH) connector E-22 in good condition?

YES : Go to Step 8.

NO : Repair or replace the damaged component(s). Refer to General (Electrical), Harness Connector Inspection.When the rear power window sub switch (RH) is operated, the rear power window (RH) should raise and lower normally.

STEP 8.Check the power window main switch for continuity.

1. Remove the power window main switch. Refer to Door Glass and Regulator.






2. Check continuity when the power window main switch is operated to "UP" or "DOWN" position.






NOTE: Set the window lock switch to UNLOCK position.

Q: Is the power window main switch normal?

YES : Go to Step 9.

NO : Replace the power window main switch. Verify that the power window works normally.

STEP 9.Check the wiring harness between power window main switch connector E-15 (terminals 4 and 6) and rear power window sub switch (RH) connector E-22 (terminals 8 and 5).

NOTE: Also check intermediate connectors C-21, C-125 and D-01.If intermediate connectors C-21, C-125 or D-01 is damaged, repair or replace the damaged component(s) as described in General (Electrical), Harness Connector Inspection.

Q: Is the wiring harness between power window main switch connector E-15 (terminals 4 and 6) and rear power window sub switch (RH) connector E-22 (terminals 8 and 5) in good condition?

YES : Replace the power window main switch. When the rear power window sub switch (RH) is operated, the rear power window (RH) should raise and lower normally.

NO : The wiring harness may be damaged or the connector(s) may have loose, corroded or damaged terminals, or terminals pushed back in the connector. Repair the wiring harness as necessary. When the rear power window sub switch (RH) is operated, the rear power window (RH) should raise and lower normally.

STEP 10. Check power window main switch connector E-15 and rear power window sub switch (LH) connector E-25 for loose, corroded or damaged terminals, or terminals pushed back in the connector.

Q: Are front power window main switch connector E-15 and rear power window sub switch (LH) connector E-25 in good condition?

YES : Go to Step 11.

NO : Repair or replace the damaged component(s). Refer to General (Electrical), Harness Connector Inspection.When the rear power window sub switch (LH) is operated, the rear power window (LH) should raise and lower normally.

STEP 11.Check the power window main switch for continuity.

1. Remove the power window main switch. Refer to Door Glass and Regulator.






2. Check continuity when the power window main switch is operated to "UP" or "DOWN" position.






NOTE: Set the window lock switch to UNLOCK position.

Q: Is the power window main switch normal?

YES : Go to Step 12.

NO : Replace the power window main switch. Verify that the power window works normally.

STEP 12.Check the wiring harness between power window main switch connector E-15 (terminals 1 and 3) and rear power window sub switch (LH) connector E-25 (terminals 8 and 5).
