- Faulty: Replace the Motor vane.
3. Check the position sensing operations when moving the
Sensor vane on and off.(Use n5 Service test mode.)
Check the conduction between the Brown wire and the
Black wire.
׻͑ Sensor On: 0V
׻͑ Sensor Off: 5V
- Faulty: Replace the Sensor vane for sensing positions.
- Normal: Replace the Motor vane and Sensor vane
4. Adjust Motion A’ssy and Find the faulty. - Faulty: Replace Motion A’ssy.
5. Check whether Motor vane is operating normally.
- Check the Motor vane operation
׻͑
Normal: 110 ~ 120V
- Check the operation of Motor vane Relay.
- CCW: Check the operating voltage between the 5pin(Red)
wire of the Main PBA CN202 connector and the
Black wire of the Main PBA CN101 connector
CW: Check the operating voltage between the
5pin(White) wire of the Main PBA CN202 connector
and the Black wire of the Main PBA CN101
connector
׻͑ Normal: 110 ~ 120V (while operating)
- Faulty: Replace the Main PBA assy.
6. Check the Power Relay. - See the “Power Relay error”.
