On-Vehicle Inspection [12/2012 - ]: Procedure
- CHECK FUEL PUMP OPERATION AND INSPECT FOR FUEL LEAK
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.NOTE:
Do not start the engine.
- Turn the Techstream on.
- for 2WD
Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the Fuel Pump / Speed.
Powertrain > Engine and ECT > Active Test
Tester Display Control the Fuel Pump / Speed - for 4WD
Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the Fuel Pump / Speed.
Powertrain > Engine and ECT > Active Test
Tester Display Control the Fuel Pump / Speed - Check the fuel pump operation.
- Check for pressure in the fuel inlet tube from the fuel line. Check that the sound of fuel flowing in the fuel tank can be heard.
If there is no sound, check the C/OPN relay, fuel pump, ECM, fuel pump control ECU and wiring connector.
- Check for pressure in the fuel inlet tube from the fuel line. Check that the sound of fuel flowing in the fuel tank can be heard.
- Check for fuel leaks.
- Check that there are no fuel leaks after performing maintenance anywhere on the system.
If there are fuel leaks, repair or replace parts as necessary.
- Check that there are no fuel leaks after performing maintenance anywhere on the system.
- CHECK FUEL PRESSURE
- Using a voltmeter, measure the battery voltage.
Refer to PROCEDURE - Step 1 , PROCEDURE - Step 1 , or PROCEDURE - Step 1
- Discharge the fuel system pressure.
Refer to PRECAUTION [12/2012 - ]
- Disconnect the cable from the negative (-) battery terminal.NOTE:
- After turning the ignition switch off, waiting time may be required before disconnecting the cable from the battery terminal. Therefore, make sure to read the disconnecting the cable from the battery terminal notice before proceeding with work.
Refer to PRECAUTION [12/2012 - ]
- When disconnecting the cable, some systems need to be initialized after the cable is reconnected.
Refer to INITIALIZATION [12/2012 - 10/2015] , INITIALIZATION [10/2015 - 08/2016] , or INITIALIZATION [08/2016 - ]
- After turning the ignition switch off, waiting time may be required before disconnecting the cable from the battery terminal. Therefore, make sure to read the disconnecting the cable from the battery terminal notice before proceeding with work.
- Disconnect the fuel tube.
Refer to PRECAUTION [12/2012 - ]
- Install SST (pressure gauge) as shown in the illustration.
- SST: 09268-45101
- 09268-41250
- 09268-41260
- 09268-41280
- 09268-41500
- 09268-41700
- 95336-08070
*1 SST (Hose) *2 Fuel Tube *3 SST (T Joint) *4 SST (Pressure Gauge) *5 SST (Fuel Tube Connector) *6 SST (Hose Band) *7 SST (Hose Joint) - SST: 09268-45101
- Wipe up any gasoline.
- Reconnect the cable to the negative (-) battery terminal.
- Start the engine.
- Measure the fuel pressure at idle.
Fuel pressure
304 to 343 kPa (3.1 to 3.5 kgf/cm2 , 44 to 50 psi)
If the pressure is not as specified, check the fuel pump and injectors.
- After checking the fuel pressure, disconnect the cable from the negative (-) battery terminal and carefully remove SST and the fuel tube connector to prevent fuel from spilling.
- Reconnect the fuel tube.
Refer to PRECAUTION [12/2012 - ]
- Inspect for fuel leaks.
Refer to PROCEDURE - Step 9
- Using a voltmeter, measure the battery voltage.
