10. Turn the ignition switch ON.
11. Turn the intelligent tester ON.
12. Select the following menu items: DIAGNOSIS / ENHANCED OBD II / ACTIVE TEST / FUEL PUMP / SPD/ON.
13. Measure the fuel pressure.
  Standard:
  
  281 to 287 kPa (2.87 to 2.93 kgf/cm ² , 40.8 to 41.7 psi)
  - If the fuel pressure is greater than the standard value, replace the fuel pump.
  - If the fuel pressure is less than the standard value, check the connection between the fuel hose and fuel pump.
14. Select the following menu items: DIAGNOSIS / ENHANCED OBD II / ACTIVE TEST / PRIMARY / FUEL PUMP / SPD / OFF.
15. Check that the fuel pressure does not change for 5 minutes.

  If the result is not as specified, check the fuel pump and fuel injector.
16. Disconnect the intelligent tester from the DLC3.
17. Disconnect the cable from the battery negative terminal.
18. Remove SST and the fuel tube connector while being careful to prevent gasoline splashes.
