Tilt Sensor Circuit Inspection

  1. CHECK FUNCTION 

    With CONSULT-II 

    With "TILT SEN" on the DATA MONITOR, operate the tilt switch to make sure voltage changes.

    CHECKING TILT SENSOR CIRCUIT FUNCTION WITHOUT CONSULT-II

    Connector Terminals (Wire color) Condition Voltage (V) (Approx.)
    (+) (-)
    M49 7 (Y/R) Ground Tilt top position 1.82
    Tilt bottom position 4.44

    OK or NG

    1. OK: Tilt sensor circuit is OK.
    2. NG: GO TO 2.
  2. CHECK HARNESS 
    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 7 (Y/R) and tilt sensor and telescopic sensor connector M28 terminals 2 (Y/R).

      7 (Y/R) - 2 (Y/R): Continuity should exist. 

    3. Automatic drive positioner control unit connector M49 terminals 7 (Y/R) and ground.

      7 (Y/R) - Ground: Continuity should not exist.
