Inspection

INSPECTION

PROCEDURE

1. INSPECT REAR HEIGHT CONTROL SENSOR SUB-ASSEMBLY LH

(a) Check the rear height control sensor sub-assembly LH.

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

(2) Connect the positive (+) end of the batteries to terminal 3 (SHB) of the rear height control sensor sub-assembly LH and the negative (-) end of the batteries to terminal 1 (SHG). While slowly moving the sensor link up and down, measure the voltage between terminal 2 (SHRR) and terminal 1 (SHG).

NOTICE:

  • Do not use rechargeable batteries as they may not output a voltage of 1.5 V.
  • Do not apply a voltage of more than 6 V.
