WINDSHIELD / WINDOWGLASS: POWER WINDOW CONTROL SYSTEM (w/ Jam Protection Function): Remote Up / Down Function does not Operate

Remote Up / Down Function does not Operate

DESCRIPTION

Operating the passenger side power window switch on the power window regulator master switch inputs a remote signal to the power window regulator switch. Then, the power window regulator switch drives the passenger side window motor.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK POWER WINDOW LOCK SWITCH





(a) Turn the window lock switch OFF and operate the passenger side power window switch on the power window regulator master switch. Check that the remote UP/DOWN function operates normally.
OK:
Remote UP/DOWN function operates normally.
OK -- END
NG -- Continue to next step.
2. CHECK MANUAL UP/DOWN FUNCTION (PASSENGER SIDE)
(a) Check that the power window can be operated with the power window regulator switch.
OK:
Manual UP/DOWN function operates normally.
NG -- GO TO PROBLEM SYMPTOMS TABLE
OK -- Continue to next step.
3. CHECK AUTO UP/DOWN FUNCTION (PASSENGER SIDE)
(a) Check that the power window can be operated with the power window regulator switch.
OK:
AUTO UP/DOWN function operates normally.
NG -- GO TO PROBLEM SYMPTOMS TABLE
OK -- Continue to next step.
4. CHECK WIRE HARNESS (REGULATOR SWITCH (PASSENGER SIDE))





(a) Disconnect the P12 regulator switch connector.
(b) Turn the ignition switch ON.
(c) Using an oscilloscope, check the waveform of the connector.
Standard:
The waveform is as shown in the illustration.






OK -- REPLACE POWER WINDOW REGULATOR SWITCH ASSEMBLY (PASSENGER SIDE)
NG -- Continue to next step.
5. CHECK WIRE HARNESS (POWER WINDOW REGULATOR SWITCH ASSEMBLY - POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY)





(a) Disconnect the P12 regulator switch connector.
(b) Disconnect the P9 regulator master switch connector.
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.
6. INSPECT POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY (WINDOW LOCK SWITCH)





(a) Remove the master switch but do not disconnect the connector.
(b) Turn the ignition switch ON.
(c) Measure the voltage of the connector.
Standard voltage:






NG -- REPLACE POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY
OK -- REPLACE POWER WINDOW REGULATOR SWITCH ASSEMBLY
