INSPECTION PROCEDURE

NOTICE:
Inspect the fuses of circuits related to this system before performing the following inspection procedure.
1.PERFORM ACTIVE TEST USING INTELLIGENT TESTER (OPERATE VSV FOR ACIS)
Hilux. Tgn26, 36 Kun25, 26, 35, 36 Ggn25.1Gr-Fe Engine Control.Sfi System.Sfi System  Acis Control Circuit
  1. Disconnect the vacuum hose.

  1. Connect an intelligent tester to the DLC3.

  1. Turn the ignition switch to ON and turn the tester on.

  1. Enter the following menus: Powertrain / Engine and ECT / Active Test / Activate the VSV for Intake Control. Operate the VSV for ACIS.

  1. Check the VSV operation when it is operated using the tester.

    OK:
    Tester Operation
    Specified Condition
    VSV ON
    Air from port E flows out through port F
    VSV OFF
    Air from port E flows out through air filter
    Text in Illustration
    *a
    VSV is ON
    *b
    VSV is OFF
    *c
    Air


NG
Go to step 4
OK


2.CHECK VACUUM HOSES (VACUUM SWITCHING VALVE - INTAKE AIR CONTROL VALVE, INTAKE MANIFOLD)
  1. Check the vacuum hoses.



NG
REPAIR OR REPLACE VACUUM HOSES
OK


3.INSPECT INTAKE MANIFOLD (INTAKE AIR CONTROL VALVE)
  1. Inspect the intake air control valve (HILUX_TGN26 RM000000V0000TX_01_0003.html).



NG
REPLACE INTAKE MANIFOLD (HILUX_TGN26 RM000002I4V00DX.html)
OK

PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE (HILUX_TGN26 RM000000PDG0R6X.html)

4.INSPECT VSV FOR ACIS
  1. Inspect the VSV for ACIS (HILUX_TGN26 RM0000014ZM00LX.html).



NG
REPLACE VSV FOR ACIS
OK


5.CHECK HARNESS AND CONNECTOR (VACUUM SWITCHING VALVE - ECM, NO. 1 INTEGRATION RELAY)
  1. Disconnect the VSV for ACIS connector.

  1. Disconnect the ECM connector.

  1. Remove the No. 1 integration relay from the engine room relay block and junction block assembly.

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

    Standard Resistance:

    Tester Connection
    Condition
    Specified Condition
    C139-2 - C129-33 (ACIS)
    Always
    Below 1 Ω
    C139-1 - 1J-5
    Always
    Below 1 Ω
    C139-2 or C129-33 (ACIS) - Body ground
    Always
    10 kΩ or higher
    C139-1 or 1J-5 - Body ground
    Always
    10 kΩ or higher


NG
REPAIR OR REPLACE HARNESS OR CONNECTOR (VSV FOR ACIS - ECM, NO. 1 INTEGRATION RELAY)
OK


6.GO TO ECM POWER SOURCE CIRCUIT
  1. Check the ECM power source circuit (HILUX_TGN26 RM000000WZ0077X.html).



NG
REPAIR ECM POWER SOURCE CIRCUIT
OK

REPLACE ECM (HILUX_TGN26 RM000000VW202SX.html)
