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 designates 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 to this
variation. When the engine output decreases, check whether all rail pressure offset values is set to 0 in the Rail
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 fuel system
related components.
1. Select the vehicle model.
2. Select [RAIL PRESSURE RESET] in [FUNCTION
SELECTION] screen.
