Diagnosis Procedure

With CONSULT

1. Turn ignition switch OFF.
2. Connect pressure gauge.
3. Start the engine and let it idle.
4. On CONSULT screen, select "FSCM" >> "DATA MONITOR" >> "FUEL PRESSSEN".
5. Check that the indicated value is between 350 kPa (3.5 bar, 3.57 kg/cm ² , 50.75 psi) and 1000 kPA (10 bar, 10.2 kg/cm ² , 145 psi).

Is the inspection result normal?

YES

INSPECTION END
