1. Check the connections for the Motor vane and Sensor vane connectors.
- Reconnect the Distributor Motor and Micro Switch connectors.
2. Check whether the coil in Motor vane is conductive.
Check the resistance between the Red and Black wire(CCW)
Check the resistance between the White and Black wire(CW).
: Remove the connectors before measuring.
► Normal: Approx. 1.625 ~ 1.796kΩ
- 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 Assy and Find the faulty.
- Faulty: Replace Motion Assy.
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 8pin(Red) wire of the
Main PBA CN401 connector and the White wire of the Main PBA CN101
connector CW: Check the operating voltage between the 7pin(White)
wire of the Main PBA CN401 connector and the White 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 check code”.
