FUEL RAIL PRESSURE RELIEF VALVE
With CONSULT-II
WARNING:

Confirm that the engine is cooled down and there are no fire hazards near the vehicle.

Prepare pans or saucers under the disconnected fuel line because the fuel may spill out.
1. Turn ignition switch OFF.
2. Remove fuel hose from fuel rail pressure relief valve.
3. Attach a blind cap or plug to removed hose.
4. Turn ignition switch ON.
5. Select “PRES REGULATOR” in “ACTIVE TEST MODE” with
CONSULT-II.
6. Start engine and keep engine speed 2,000 rpm.
7. Raise fuel pressure to 160 MPa with touching “UP” or “Qu” on
the CONSULT-II screen.
8. Confirm that the fuel does not come out from the fuel rail pres-
sure relief valve.
WARNING:

Be careful not to allow leaked fuel to contaminate engine
compartment. Especially, ensure to keep engine mount
insulator clear of fuel.

If the fuel comes out, stop the engine immediately.
