  Warning
  • Fuel is very flammable liquid. If fuel spills or leaks from the pressurized fuel system, it will cause serious injury or death and facility breakage. Fuel can also irritate skin and eyes. To prevent this, always complete the “Fuel Leakage Inspection”.
  • A person charged with static electricity could cause a fire or explosion, resulting in death or serious injury. Before performing work on the fuel system, discharge static electricity by touching the vehicle body.

Fuel Leakage Inspection

Using M-MDS

1. Connect the M-MDS to the DLC-2.

2. Start the fuel pump using the “FP” simulation function. (See ON-BOARD DIAGNOSTIC TEST [L8, LF].)

3. Verify that there is no fuel leakage from the pressurized parts.

  Standard

  There shall be no leakage after 5 min.

4. In the case of fuel leakage, replace the following components and then do the recheck by the fuel leakage checking procedure.

  • If there is leakage, replace the fuel hoses and clips.
  • If there is damage on the seal on the fuel pipe side, replace the fuel pipe.

Without using M-MDS

1. Remove the battery cover. (See BATTERY REMOVAL/INSTALLATION [L8, LF].)

2. Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [L8, LF].)

3. Short the check connector terminal F/P to ground using a jumper wire.

4. Connect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [L8, LF].)

5. Turn the ignition switch to the ON position to operate the fuel pump.

6. Verify that there is no fuel leakage from the pressurized parts.

  Standard

  There shall be no leakage after 5 min.

7. In the case of fuel leakage, replace the following components and then do the recheck by the fuel leakage checking procedure.

  • If there is leakage, replace the fuel hoses and clips.
  • If there is damage on the seal on the fuel pipe side, replace the fuel pipe.
