OK or NG 

OK : Telescopic sensor circuit is OK.

NG : GO TO 2.

1. Disconnect automatic drive positioner control unit connector and tilt sensor and telescopic sensor connector.
2. Check continuity harness between automatic drive positioner control unit connector M49 terminals 23 and tilt sensor and telescopic sensor connector M28 terminals 3.

   23 (Y/B) - 3 (Y/B) : Continuity should exist. 

3. Check continuity harness between automatic drive positioner control unit connector M49 terminals 23 and ground.

   23 (Y/B) - Ground : Continuity should not exist.
