    *a

    Component without harness

    (Front Height Control Sensor Sub-assembly LH)

    1. Connect 3 dry cell batteries (1.5 V) in a series.

    2. Connect the positive (+) lead from the batteries to terminal 3, and the negative (-) lead from the batteries to terminal 1.

    3. Measure the voltage between terminals 2 and 1 while slowly moving the link up and down.

      Standard Voltage
      Tester Connection Condition Specified Condition
      2 (SHRL) - 1 (SHG) +45° (High) 4.05 V
      0° (Normal) 2.25 V
      -45° (Low) 0.45 V

      If the result is not as specified, replace the front height control sensor sub-assembly LH.

  2. INSPECT REAR HEIGHT CONTROL SENSOR SUB-ASSEMBLY LH

    Component without harness

    (Rear Height Control Sensor Sub-assembly LH)

    1. Connect 3 dry cell batteries (1.5 V) in a series.

    2. Connect the positive (+) lead from the batteries to terminal 3, and the negative (-) lead from the batteries to terminal 1.

    3. Measure the voltage between terminals 2 and 1 while slowly moving the link up and down.

      Standard Voltage
      Tester Connection Condition Specified Condition
      2 (SHRL) - 1 (SHG) +45° (High) 4.05 V
      0° (Normal) 2.25 V
      -45° (Low) 0.45 V

      If the result is not as specified, replace the rear height control sensor sub-assembly LH.
