Component Inspection

INSPECTION







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




b. Apply battery voltage and check the illuminates.

HINT: Whether the switch illuminates or not will not affect the function of the LH side.

If the result is not as specified, replace the bulb.







2. INSPECT SATELLITE SWITCH
a. Inspect the resistance of the back door switch.
If the result is not as specified, replace the switch.




b. Apply battery voltage and check whether the switch illuminates.

HINT: Whether the switch illuminates or not will not affect the function of the RH side.

If the result is not as specified, replace the bulb.







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







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







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




6. INSPECT POWER BACK DOOR DRIVE UNIT
a. Remove the unit.




b. Apply battery voltage to the terminals and check the motor operation.
If the result is not as specified, replace the drive unit.




c. Check the resistance of the clutch terminals.
If the result is not as specified, replace the drive unit.

d. Reinstall the unit with the connector connected.







e. Check the pulse of the pulse sensor.
1. Using an oscilloscope, check the pulse generated when the door is manually opened and closed.
If the result is not as specified, replace the drive unit.

HINT: A cycle of the pulse changes between approx. 10 to 20 msec. according to the speeds that the slide door is moving.

f. With the connector connected, check the voltage of the terminals of the power back door drive unit connector.







7. 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.
