Inspection Procedure

WARNING: This page is about a different car, the 2004 Toyota Camry. However, it is still accessible from the selected car via links, so may be relevant.

CHECK DIAGNOSTIC CODE OUTPUT
1. Check the diagnostic code.
  HINT:
  
  AUTO illumination starts blinking after the ignition switch is turned ON to OFF and stops in approximately 43 seconds or when the driver's door is once opened then closed (the conditions to operate the window automatically after key-off are satisfied).
  1. Check whether the AUTO illumination for the power window regulator master switch blinks after the ignition switch is turned ON to OFF.
  HINT:
  - NG - A means that blinks in the 1 or 3 way.
  - NG - B means that blinks occurs in the 2 way.

1. NG-B: Go to step 4
2. OK: REPLACE POWER WINDOW REGULATOR MASTER SWITCH ASSY
3. NG-A: Go to next step
CHECK POWER WINDOW REGULATOR MASTER SWITCH ASSY
1. Remove the power window regulator master switch (the power window regulator master switch connector is connected).
2. Check the voltage between terminal SGND (2) and terminal LMT (17) of the D12 power window regulator master switch connector when the driver's door glass is not in the fully closed.
  Voltage: 10 - 14 V

2. OK: Go to next step

CHECK WIRE HARNESS

Disconnect the D12 power window regulator master switch connector.
Disconnect the P9 power window regulator motor connector.
Check the continuity between the disconnected connectors.

Standard:

CONTINUITY CONDITION BETWEEN CONNECTORS

Symbols (Terminal No.) [Switch <--> Motor]	Specified condition
LMT (D12-17) <--> LMT (P9-2)	Continuity

NG: REPLACE POWER WINDOW REGULATOR MOTOR ASSY LH
OK: REPLACE POWER WINDOW REGULATOR MOTOR ASSY LH

CHECK PULSE SENSOR OF POWER WINDOW REGULATOR MOTOR
1. While the power window regulator motor is operating, check that the voltage between terminal SGND (2) and terminal PLS (14) of the D12 power window regulator master switch connector.
  Voltage: Output waveforms of pulse
