Height Control Compressor Inspection

Measure the resistance of the exhaust valve.

1. Measure the resistance according to the value(s) in the table below.
   

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   2 (L) - 1 (B)	15 to 25°C (59 to 77°F)	10 to 14 Ω

   *a	Component without harness connected (Exhaust Valve)

Check the exhaust valve operation.

1. Connect a positive (+) lead from the battery to terminal 2 (B), and a negative (-) lead to terminal 1 (L).
   

2. Check the operating sound of the height control valve.
   

   OK:

   It makes an operating sound.

   If the result is not as specified, replace the height control compressor.
   

Check the compressor operation.

1. Apply 12 V battery voltage to the compressor motor and check the operation of the motor.
   

   OK:

   Measurement Condition	Specified Value
   12 V battery positive (+) → Terminal 1 (B) 12 V battery negative (-) → Terminal 2 (E)	Motor operates

   NOTICE:

   1. Do not operate the height control compressor for 60 seconds or more.
      
   2. Stop applying voltage immediately if the compressor stops operating because a short will occur and the compressor motor will lock up, causing a flow of excessive current.
      
   If the result is not as specified, replace the height control compressor.
