With CONSULT-II
WARNING:
lConfirm that the engine is cooled down and there are no fire hazards near the vehicle.
lPrepare 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
