INSPECTION PROCEDURE

NOTICE:

After replacing the ECM, the new ECM needs registration (Toyota Fortuner RM0000012XK04AX.html) and initialization (Toyota Fortuner RM000000TIN04KX.html).

HINT:

Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when a malfunction is 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. Connect the intelligent tester to the DLC3.
   

2. Disconnect the vacuum hoses from the vacuum switching valve (for Swirl Control Valve).
   

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

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

5. Check the VSV operation when it is operated using the intelligent 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

6. Reconnect the vacuum hoses.
   

1. Inspect the vacuum switching valve (for swirl control valve) (Toyota Fortuner RM0000046SD00GX.html).
   

1. Disconnect the vacuum switching valve (for swirl control valve) connector.
   

2. Measure the voltage according to the value(s) in the table below.
   

   Standard Voltage:

   Tester Connection	Switch Condition	Specified Condition
   S29-2 - Body ground	Ignition switch ON	11 to 14 V

1. Disconnect the vacuum switching valve (for swirl control valve) connector.
   

2. Disconnect the ECM connector.
   

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

   Standard Resistance:

   
   

   Tester Connection	Condition	Specified Condition
   S29-1 - E7-15 (SCV)	Always	Below 1 Ω
   S29-1 or E7-15 (SCV) - Body ground	Always	10 kΩ or higher

4. Reconnect the vacuum switching valve (for swirl control valve) connector.
   

5. Reconnect the ECM connector.
   

1. Replace the ECM (Toyota Fortuner RM0000043H100CX.html).
   

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

2. Disconnect the No. 1 integration relay connector.
   

3. Disconnect the vacuum switching valve (for swirl control valve) connector.
   

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

   Standard Resistance:

   
   

   Tester Connection	Condition	Specified Condition
   1J-5 - S29-2	Always	Below 1 Ω
   1J-5 or S29-2 - Body ground	Always	10 kΩ or higher

5. Reinstall the No. 1 integration relay.
   

6. Reconnect the No. 1 integration relay connector.
   

7. Reconnect the vacuum switching valve (for swirl control valve) connector.
   

1. Check the ECM power source circuit (Toyota Fortuner RM000000TI2042X.html).
   

1. Replace the vacuum switching valve (for swirl control valve) (Toyota Fortuner RM000002S4L00NX.html).
   

1. Repair or replace harness or connector.
   

1. Connect the intelligent tester to the DLC3.
   

2. Clear the DTCs (Toyota Fortuner RM000000PDK0TWX.html).
   

3. Start the engine and wait for 3 seconds or more.
   

4. Enter the following menus: Powertrain / Engine and ECT / DTC.
   

5. Confirm that the DTC is not output again.
