Power Window can be Operated After Power Switch is Turned OFF Even if Operative Conditions are not Met

DESCRIPTION

The body ECU keeps power supplied to the power window regulator master switch and the regulator switch for 43 seconds after the power switch is turned OFF. However, the body ECU will cut power to the master switch if: 1) either front door is opened, 2) a signal from either of the front door courtesy light switches is input to the ECU within the 43 seconds, or 3) 43 seconds have passed.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK OPERATION FUNCTION AFTER POWER SWITCH IS TURNED OFF
(a) After turning the power switch OFF:
(1) If either front door is opened within 43 seconds but the power window can still operate, proceed to A.
(2) If 43 seconds pass but the power window can still operate, proceed to B.
B -- REPLACE POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY
A -- Continue to next step.

2. READ VALUE USING TECHSTREAM (COURTESY LIGHT SWITCH)
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch ON (IG) and press the Techstream main switch ON.
(c) Read the Data List according to the displays on the tester.

Body ECU





OK:
ON (door is open) appears on the screen.
OK -- REPLACE DRIVER SIDE JUNCTION BLOCK ASSEMBLY
NG -- Continue to next step.

3. INSPECT FRONT DOOR COURTESY LIGHT SWITCH ASSEMBLY




(a) Measure the resistance.






NG -- REPLACE FRONT DOOR COURTESY LIGHT SWITCH ASSEMBLY
OK -- Continue to next step.

4. CHECK WIRE HARNESS (COURTESY LIGHT SWITCH - JUNCTION BLOCK)




(a) Disconnect the D7*1 or D8*2 switch connector.
(b) Disconnect the 1D junction block connector.
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- REPLACE DRIVER SIDE JUNCTION BLOCK (BODY ECU)
