Component Inspection
INSPECTION1. INSPECT POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY
a. Measure the resistance of the switch when the switch is operated.
If the result is not as specified, replace the master switch assembly.
b. Check the window lock switch.
If the result is not as specified, replace the master switch assembly.
c. Check the door control switch.
If the result is not as specified, replace the master switch assembly.
2. INSPECT POWER WINDOW REGULATOR SWITCH ASSEMBLY
a. Measure the resistance of the switch when the switch is operated.
If the result is not as specified, replace the regulator switch assembly.
3. INSPECT DOOR CONTROL SWITCH ASSEMBLY
a. Measure the resistance of the switch when the switch is operated.
If the result is not as specified, replace the switch.
4. INSPECT POWER WINDOW REGULATOR MOTOR ASSEMBLY LH FRONT
a. Inspect operation of the power window regulator motor (for driver side door).
NOTE:
- Be sure not to apply the battery voltage to terminals 3 (PLS), 4 (LMT) and 5 (E) of the power window regulator motor assembly LH connector, because it might damage the pulse sensor and the limit switch.
- Be sure to reset the power window regulator motor assembly (to the initial setting of the limit switch) when the power window regulator motor assembly LH is installed to the regulator.
1. Check that the motor operates smoothly when the battery voltage is applied to each terminal of the connector.
If the result is not as specified, replace the motor assembly.
b. Inspect operation of the PTC inside the power window regulator motor.
NOTE: Be sure that the power window regulator and door glass are installed to the vehicle before inspection.
1. Set an electrical tester DC 400 A probe to the wire harness of terminal 1 (D) or 2 (U).
NOTE: Match the arrow mark of the probe with the current direction.
2. Fully close the door glass.
3. When approximately 60 seconds have elapsed after the door glass has been fully closed, check the changing time of the current, from 16 to 34 A into 1 A, when the power window regulator master switch is pulled UP furthermore (inspection of current cut-off..
Standard: Approximately 4 to 90 seconds
4. When approximately 60 seconds have elapsed after the inspection of the current cut-off, check that the door glass goes down when the power window regulator master switch is pushed DOWN.
5. INSPECT POWER WINDOW REGULATOR MOTOR ASSEMBLY RH FRONT
a. Inspect operation of the power window regulator motor (for passenger side door).
NOTE:
- Be sure not to apply the battery voltage to terminals 3 (PLS), 4 (LMT) and 5 (E) of the power window regulator motor assembly RH connector, because it might damage the pulse sensor and the limit switch.
- Be sure to reset the power window regulator motor assembly (to the initial setting of the limit switch) when the power window regulator motor assembly RH is installed to the regulator.
1. Check that the motor operates smoothly when the battery voltage is applied to each terminal of the connector.
If the result is not as specified, replace the motor assembly.
b. Inspect operation of the PTC inside the power window regulator motor.
NOTE: Be sure that the power window regulator and door glass are installed to the vehicle before inspection.
1. Set an electrical tester DC 400 A probe to the wire harness of terminal 1 (U) or 2 (D).
NOTE: Match the arrow mark of the probe with the current direction.
2. Close the door glass fully.
3. When approximately 60 seconds have elapsed after the door glass has been fully closed, check the changing time of the current, from 16 to 34 A into 1 A, when the power window regulator switch is pulled UP furthermore (inspection of current cut-off).
Standard: Approximately 4 to 90 seconds
4. When approximately 60 seconds have elapsed after the inspection of the current cut-off, check that the door glass goes down when the power window regulator switch is pushed OWN.
