INSPECTION PROCEDURE

CHECK MANUAL UP/DOWN FUNCTION (FOR DRIVER SIDE)

CHECK LIGHT OF POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY

RESET FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY LH

CHECK HARNESS AND CONNECTOR (POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY - FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY LH)

CHECK POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY (PLS, PLS2 SIGNAL)

DESCRIPTION

1. The recorded power window fully closed position, which is stored in the power window regulator master switch assembly, was erased as a result of: 1) the PWR H-fuse or DOOR fuse being replaced; or 2) the battery cable and the master switch's connector being disconnected.
   
2. The power window regulator master switch assembly has a malfunction.
   
3. The pulse sensors in the front power window regulator motor assembly LH have a malfunction.
   
4. The wiring between the power window regulator master switch assembly and the front power window regulator motor assembly RH is open or short-circuited.

INSPECTION PROCEDURE

1. Check that the manual up/down function operates normally.
   

   OK:

   Manual up/down function operates normally.
   

1. Turn the ignition switch to ON.
   

2. Operate the master switch's driver side power window switch for 2 seconds or more.
   

3. Check the blinking pattern of the AUTO light. Compare the blinking pattern with the illustration.

1. Check that the power window operates normally after reset (HILUX_TGN26 RM000001DJB01FX.html).
   

   OK:

   Power window operates normally.
   

1. Disconnect the I5 power window regulator master switch assembly connector.
   

2. Disconnect the I3 front power window regulator motor assembly LH connector.
   

3. Measure the resistance according to the value(s) in the table below.
   

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   I5-3 (VCC) - I3-4 (SSRB)	Always	Below 1 Ω
   I5-14 (PLS) - I3-5 (PLS)	Always	Below 1 Ω
   I5-17 (PLS2) - I3-3 (PLS2)	Always	Below 1 Ω
   I5-2 (GND) - I3-6 (E)	Always	Below 1 Ω
   I5-3 (VCC) or I3-4 (SSRB) - Body ground	Always	10 kΩ or higher
   I5-14 (PLS) or I3-5 (PLS) - Body ground	Always	10 kΩ or higher
   I5-17 (PLS2) or I3-3 (PLS2) - Body ground	Always	10 kΩ or higher

1. Remove the power window regulator master switch assembly with its connectors still connected (HILUX_TGN26 RM000002STU07WX.html).
   

2. Using an oscilloscope, check the waveform.
   

   OK:

   Tester Connection	Switch Condition	Specified Condition
   I5-14 (PLS) - Body ground	Ignition switch ON, driver side power window switch off → up or down	Pulse waveform is output
   I5-17 (PLS2) - Body ground
