Fuel Pumps 2.
• The following DTCs are stored in the engine control module (ECM), J623 (address word

warning light.
• DTC P008800 (fuel, rail/system pressure too high)
• DTC P01C900 (fuel, rail/system pressure bank 2 too high)
Technical Background
The fuel metering valve of the high-pressure fuel pump is controlled by a specific on/off ratio. If there is a low
system voltage, the on/off ratio may not be enough to keep the fuel metering valve constant in all areas. In such a
situation, the fuel metering valve is deactivated and the high-pressure fuel pump switches to full supply mode.
Because the increased rail pressure does not match the respective driving situation, the DTC appears.
Production Solution
ECM software update.
