HEIGHT CONTROL COMPRESSOR INSPECTION

PROCEDURE


  1. INSPECT NO. 1 HEIGHT CONTROL COMPRESSOR (EXHAUST VALVE)


    1. Measure the resistance of the exhaust valve.


      1. B004UTDC01
        *a

        Component without harness connected

        (No. 1 Height control compressor)

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

        Standard resistance
        Tester Connection Condition Specified Condition
        L182-1 (L) - L182-2 (B) at 20°C (68°F) 9.36 to 10.14 Ω

        Tech Tips

        If the result is not as specified, replace the No. 1 height control compressor.

    2. Check the exhaust valve operation.


      1. B004UTDC02
        *a

        Component without harness connected

        (No. 1 Height control compressor)

        Apply battery voltage to each terminal and check the operation of the valve inside the solenoid.

        Note

        Do not operate the valve for 60 seconds or more.

        Standard
        Tester Connection Specified Condition

        Battery positive (+) → L182-1 (+)

        Battery negative (-) → L182-2 (-)

        Operates (operating sound heard)

        Tech Tips

        If the result is not as specified, replace the No. 1 height control compressor.

  2. INSPECT HEIGHT CONTROL COMPRESSOR (COMPRESSOR MOTOR)


    1. Check the compressor operation.


      1. B004UZRC01
        *a

        Component without harness connected

        (No. 1 Height control compressor)

        Apply battery voltage to each terminal and check the operation of the No. 1 height control compressor (compressor motor).

        Standard
        Tester Connection Specified Condition

        Battery positive (+) → P10-1 (B)

        Battery negative (-) → P10-2 (E)

        Operates (operating sound heard)

        Note


        • Do not operate the height control compressor for 60 seconds or more.

        • Since a short and a lock-up inside the height control compressor cause excessive current to flow, stop operation immediately when the compressor motor does not operate.

        Tech Tips

        If the result is not as specified, replace the No. 1 height control compressor.

  3. INSPECT NO. 3 HEIGHT CONTROL VALVE


    1. B004RE1C01
      *a

      Component without harness connected

      (No. 1 Height control compressor)

      Measure the resistance of the No. 3 height control valve.


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

        Standard resistance
        Tester Connection Condition Specified Condition
        L181-1(SMT1) - L181-2(E) at 20°C (68°F) 9.36 to 10.14 Ω
        L181-3(SMSI) - L181-2(E)
        L183-1(SMOS) - L183-2(E)
        L183-3(SMTO) - L183-2(E)

        Tech Tips

        If the result is not as specified, replace the No. 1 height control compressor.

    2. B004RE1C01
      *a

      Component without harness connected

      (No. 1 Height control compressor)

      Apply battery voltage to each terminal and check the operation of the valve inside the solenoid.

      Note

      Do not operate the valve for 60 seconds or more.

      Standard
      Tester Connection Specified Condition

      Battery positive (+) → L181-1 (SMTI)

      Battery negative (-) → L181-2 (E1)

      Operates (operating sound heard)

      Battery positive (+) → L181-3 (SMSI)

      Battery negative (-) → L181-2 (E1)

      Operates (operating sound heard)

      Battery positive (+) → L183-1 (SMOS)

      Battery negative (-) → L183-2 (E2)

      Operates (operating sound heard)

      Battery positive (+) → L183-3 (SMTO)

      Battery negative (-) → L183-2 (E2)

      Operates (operating sound heard)

      Tech Tips

      If the result is not as specified, replace the No. 1 height control compressor.
