Rail Pressure Reset

Rail Pressure Reset Procedures

The engine ECU needs a specific amount of fuel according to the fuel supply lines and vehicle driving conditions.

However, if the fuel supply (pressure) is not achieved due to, for instance, defective fuel system, ECU desig-nates the offset value to the high pressure pump to compensate it.

The fuel supply pressure varies according to the offset value and the engine output could be decreased due tothis variation. When the engine output decreases, check whether all rail pressure offset values is set to 0 in theRail Pressure Reset screen in SCAN-100. If the setting value is not 0, measure the fuel pressure with a tester.If any defective is found, repair the affected components and reset the rail pressure offset value to 0.

The rail pressure reset procedures should be done after replacing any high pressure pump and fuelsystem related components.

1. Select the vehicle model.

2. Select “2] RAIL PRESSURE RESET” in “FUNCTIONSELECTION” screen.

3. Enter the current rail pressure value and press[ENTER] to reset the offset value.

4. The screen returns back to step 3 after displayingthe [RAIL PRESSURE RESET IS SUCCESSFUL]message.

• If the offset value is not set to 0, check the fuel pres-sure and other DTC generations before starting therail pressure reset operation.
