resistance change.
Are the resistance equal to specified value?
1. Disconnect the HVC controller.
2. Using Motor Control Table, measure the resis-
tance between the specified terminals of the
specified HVC controller.
3. Change the mode settings and observe the
resistance change.
Are the resistance equal to specified value?
Replace the HVC controller.
Is the repair complete?
Repair open or short circuits between HVC controller
and mode moor actuator.
Is the repair complete?
Replace mode control motor.
Is the repair complete?
1. Examine the affected door in the unit for proper
attachment to the actuator.
2. Check the actuator connection to the door.
3. Check that the connector is properly connected.
Is everything connected properly?
