Inspection [12/2017 - ]: Procedure
- INSPECT NO. 1 HEIGHT CONTROL COMPRESSOR (EXHAUST VALVE)
- Measure the resistance of the exhaust valve.
- 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 *a Component without harness connected
(No. 1 Height Control Compressor)HINT:
If the result is not as specified, replace the No. 1 height control compressor.
- Measure the resistance according to the value(s) in the table.
- Check the exhaust valve operation.
- 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.
*a Component without harness connected
(No. 1 Height Control Compressor)Standard
Tester Connection Specified Condition Battery positive (+) → L182-1 (-)
Battery negative (-) → L182-2 (+)Operates (operating sound heard) HINT:
If the result is not as specified, replace the No. 1 height control compressor.
- Apply battery voltage to each terminal and check the operation of the valve inside the solenoid.
- Measure the resistance of the exhaust valve.
- INSPECT HEIGHT CONTROL COMPRESSOR (COMPRESSOR MOTOR)
- Check the compressor operation.
- 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.
*a Component without harness connected
(No. 1 Height Control Compressor)HINT:
If the result is not as specified, replace the No. 1 height control compressor.
- Apply battery voltage to each terminal and check the operation of the No. 1 height control compressor (compressor motor).
- Check the compressor operation.
- INSPECT NO. 3 HEIGHT CONTROL VALVE
- Measure the resistance of the No. 3 height control valve.
*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 L181-1 (SMTI) - L181-2 (E1) at 20°C (68°F) 9.36 to 10.14 Ω L181-3 (SMSI) - L181-2 (E1) at 20°C (68°F) 9.36 to 10.14 Ω L183-1 (SMOS) - L183-2 (E2) at 20°C (68°F) 9.36 to 10.14 Ω L183-3 (SMTO) - L183-2 (E2) at 20°C (68°F) 9.36 to 10.14 Ω HINT:
If the result is not as specified, replace the No. 1 height control compressor.
- Measure the resistance according to the value(s) in the table.
- 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) HINT:
If the result is not as specified, replace the No. 1 height control compressor.
*a Component without harness connected
(No. 1 Height Control Compressor)
- Measure the resistance of the No. 3 height control valve.
