INSPECTION PROCEDURE

NOTICE:

Inspect the fuses of circuits related to this system before performing the following inspection procedure.
After replacing the ECM, the new ECM needs registration (HILUX_TGN26 RM0000012XK05AX.html) and initialization (HILUX_TGN26 RM000000TIN058X.html).

HINT:

Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

1.PERFORM ACTIVE TEST USING GTS (ACTIVATE THE VSV FOR SWIRL CONTROL VALVE)

Hilux. Tgn26, 36 Kun25, 26, 35, 36 Ggn25.1Kd-Ftv Engine Control.Ecd System (For Dpf).

P2009 Intake Manifold Runner Control Circuit Low (Bank 1)

Connect the GTS to the DLC3.

Disconnect the vacuum hoses from the No. 1 vacuum switching valve (for swirl control valve).

Turn the ignition switch to ON and turn the GTS on.

Enter the following menus: Powertrain / Engine / Active Test / Activate the VSV for Swirl Control Valve.

Check the VSV operation when it is operated using the GTS.
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

Reconnect the vacuum hoses.

Go to step 2

CHECK FOR INTERMITTENT PROBLEMS (HILUX_TGN26 RM000000PDQ0YUX.html)

2.INSPECT NO. 1 VACUUM SWITCHING VALVE FOR SWIRL CONTROL VALVE (RESISTANCE)

Inspect the No. 1 vacuum switching valve (for swirl control valve) (HILUX_TGN26 RM0000053UN004X_01_0001.html).

Go to step 8

OK

3.INSPECT NO. 1 VACUUM SWITCHING VALVE (FOR SWIRL CONTROL VALVE) (POWER SOURCE VOLTAGE)

Disconnect the No. 1 vacuum switching valve (for swirl control valve) connector.

Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection
Switch Condition
Specified Condition
C128-2 - Body ground
Ignition switch ON
11 to 14 V

Reconnect the No. 1 vacuum switching valve (for swirl control valve) connector.

Go to step 6

OK

4.CHECK HARNESS AND CONNECTOR (NO. 1 VACUUM SWITCHING VALVE (FOR SWIRL CONTROL VALVE) - ECM)

Disconnect the No. 1 vacuum switching valve (for swirl control valve) connector.

Disconnect the ECM connector.

Measure the resistance of the wire harness side connectors.

Standard Resistance:

Tester Connection
Condition
Specified Condition
C128-1 - C164-7 (SCV)
Always
Below 1 Ω
C128-1 or C164-7 (SCV) - Body ground
Always
10 kΩ or higher

Reconnect the No. 1 vacuum switching valve (for swirl control valve) connector.

Reconnect the ECM connector.

Go to step 9

OK

5.REPLACE ECM

Replace the ECM (HILUX_TGN26 RM0000013Z001IX.html).

Go to step 10

6.CHECK HARNESS AND CONNECTOR (NO. 1 VACUUM SWITCHING VALVE (FOR SWIRL CONTROL VALVE) - NO. 1 INTEGRATION RELAY)

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

Disconnect the No. 1 integration relay connector.

Disconnect the No. 1 vacuum switching valve (for swirl control valve) connector.

Measure the resistance of the wire harness side connectors.

Standard Resistance:

Tester Connection
Condition
Specified Condition
1J-5 - C128-2
Always
Below 1 Ω
1J-5 or C128-2 - Body ground
Always
10 kΩ or higher

Reinstall the No. 1 integration relay.

Reconnect the No. 1 integration relay connector.

Reconnect the No. 1 vacuum switching valve (for swirl control valve) connector.

Go to step 9

OK

7.INSPECT ECM POWER SOURCE CIRCUIT

Check the ECM power source circuit (HILUX_TGN26 RM000000TI2076X.html).

Go to step 10

8.REPLACE VACUUM CONTROL VALVE SET

Replace the vacuum control valve set (HILUX_TGN26 RM0000044GF00OX_01_0064.html).

Go to step 10

9.REPAIR OR REPLACE HARNESS OR CONNECTOR

Repair or replace harness or connector.

NEXT

10.CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED

Connect the GTS to the DLC3.

Clear the DTCs (HILUX_TGN26 RM000000PDK12TX.html).

Start the engine and wait for 3 seconds or more.

2 seconds after the engine is started, race the engine for 1 second.

Enter the following menus: Powertrain / Engine / Trouble Codes.

Confirm that the DTC is not output again.
