Result:
OK
See step 3
- PERFORM ACTIVE TEST USING TECHSTREAM (EXHAUST SOLENOID)
- Connect the Techstream to the DLC3.
- Turn the engine switch on (IG), and turn the Techstream main switch on.
- Enter the following menus: Chassis / Air suspension / Active Test.AIR SUSPENSION
Tester Display Test Part Control Range Diagnostic Note Exhaust Solenoid Exhaust solenoid valve ON or OFF Operation sound of solenoid (clicking sound) can be heard OK
Operation of solenoid (clicking sound) can be heard
Result:
NG
REPLACE NO. 1 HEIGHT CONTROL COMPRESSOR
(Refer to REMOVAL [08/2015 - ] )
Result:
OK
See step 4
- INSPECT NO. 1 HEIGHT CONTROL COMPRESSOR (EXHAUST SOLENOID VALVE)
- Turn the engine switch off.
- Disconnect Q3 solenoid valve connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition 1 - 2 20°C (68°F) 10 to 14 Ω - Connect the battery positive (+) lead to terminal 1 and the negative (-) lead to terminal 2 of the solenoid valve connector. Then check that the valve makes an operating sound.
OK
Operation of solenoid (clicking sound) can be heard
Result:
NG
REPLACE NO. 1 HEIGHT CONTROL COMPRESSOR
(Refer to REMOVAL [08/2015 - ] )
Result:
OK
See step 5
- CHECK HARNESS AND CONNECTOR (EXHAUST SOLENOID VALVE - ECU AND BODY GROUND)
- Disconnect the O61 ECU connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition Q3-1 - O61-9 (SLEX) Always Below 1 Ω Q3-1 or O61-9 (SLEX) - Body ground Always 10 kΩ or higher Q3-2 - Body ground Always Below 1 Ω
Result:
OK
REPLACE SUSPENSION CONTROL ECU
(Refer to REMOVAL [08/2015 - ] )
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
- Disconnect the O61 ECU connector.
