Component Inspection

INSPECTION







1. INSPECT POWER BACK DOOR OFF SWITCH
a. Check the resistance of the switch.
If the result is not as specified, replace the switch.







2. INSPECT POWER BACK DOOR OPENER/CLOSER SWITCH
a. Check that the switch illuminates.
If the result is not as specified, replace the switch assembly or bulb.







b. Check the resistance of the switch.
If the result is not as specified, replace the switch.







3. INSPECT BACK DOOR OPENER SWITCH
a. Check the resistance of the switch.
If the result is not as specified, replace the switch.







4. INSPECT POWER BACK DOOR CLOSER SWITCH
a. Check the resistance of the switch.
If the result is not as specified, replace the switch.







5. INSPECT POWER BACK DOOR TOUCH SENSOR LH
a. Check the resistance of the sensor.
If the result is not as specified, replace the sensor.







6. INSPECT POWER BACK DOOR TOUCH SENSOR RH
a. Check the resistance of the sensor.
If the result is not as specified, replace the sensor.







7. INSPECT POWER BACK DOOR DRIVE UNIT
a. Remove the unit.
b. Apply battery voltage to the terminals and check the motor operation.




c. Check the resistance of the clutch terminals.
d. Reinstall the unit with the connector connected. If the result is not as specified, replace the drive unit.







e. Check the pulse of the pulse sensor.
1. Using an oscilloscope, check the pulse generated when the door is manually opened and closed.

HINT: A cycle of the pulse changes between approx. 10 to 20 msec. according to the speeds that the slide door is moving.
If the result is not as specified, replace the drive unit.







8. POWER BACK DOOR WARNING BUZZER
a. Check the resistance of the buzzer.
If the result is not as specified, replace the buzzer.

NOTE:
- The circuit that causes the buzzer to sounds is built into the back door ECU, not around the buzzer.
- Directly applying battery voltage to the buzzer does not cause the buzzer to sound.
