ACIS Control Circuit [03/2014 - ]: Procedure
- PERFORM ACTIVE TEST USING TECHSTREAM (ACTIVATE THE VSV FOR INTAKE CONTROL)
- Connect the Techstream to the DLC3.
- Turn the engine switch on (IG).
- Turn the Techstream on.
- Enter the following menus: Powertrain / Engine / Active Test / Activate the VSV for Intake Control.
- Check if operating noise can be heard when operating the intake air control valve assembly using the Techstream.
OK
Operating noise can be heard.
NG → See step 2
OK → See step 5
- CHECK INTAKE AIR SURGE TANK ASSEMBLY (INTAKE AIR CONTROL VALVE ASSEMBLY OPERATION)
- Inspect the intake air control valve assembly. Refer to ON-VEHICLE INSPECTION [03/2014 - ] - Step 1 .
NG → See step 6
OK: Go to next step
- CHECK HARNESS AND CONNECTOR (INTAKE AIR CONTROL VALVE ASSEMBLY VOLTAGE)
- Disconnect the intake air control valve assembly connector.
- Turn the engine switch on (IG).
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Switch Condition Specified Condition D5-2 - Body ground Engine switch on (IG) 11 to 14 V TEXT IN ILLUSTRATION*a Front view of wire harness connector
(to Intake Air Control Valve Assembly)
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (EFI NO. 2 FUSE - INTAKE AIR CONTROL VALVE ASSEMBLY)
OK: Go to next step
- Disconnect the intake air control valve assembly connector.
- CHECK HARNESS AND CONNECTOR (INTAKE AIR CONTROL VALVE ASSEMBLY - ECM)
- Disconnect the intake air control valve assembly connector.
- Disconnect the ECM connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance (Check for Open)
Tester Connection Condition Specified Condition D5-1 - D1-62 (ACIS) Always Below 1 Ω Standard Resistance (Check for Short)
Tester Connection Condition Specified Condition D5-1 or D1-62 (ACIS) - Body ground Always 10 kΩ or higher
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (INTAKE AIR CONTROL VALVE ASSEMBLY - ECM)
OK → See step 7
- PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE. Refer to PROBLEM SYMPTOMS TABLE [03/2014 - ]
