CHECK ADP STEERING TILT SWITCH HARNESS CONTINUITY
1. Disconnect automatic drive positioner control unit and ADP steering switch.
2. Check continuity between automatic drive positioner control unit connector M41 terminals 1, 17 and ADP steering switch connector M16 terminals 2, 3.
  1 (Y/G) - 2 (Y/G): Continuity should exist.
  
  17 (LG/B) - 3 (LG/B): Continuity should exist.
3. Check continuity between automatic drive positioner control unit connector M41 terminals 1, 17 and ground.
  1 (Y/G) - Ground: Continuity should not exist.
  
  17 (LG/B) - Ground: Continuity should not exist.
