186003461 - 1058OE Methane pressure in low pressure circuit check (BIPOWER)

• Connect the tester.
• Select EOBD methane gas injection in Control Unit Test mode.
• Press the Select button in the Parameters ambient.
• Identify the Pressure at flute item.
• With the engine running, check that the pressure at the flute is around 10 bar.
• If this pressure value is lower, check that the high pressure is not less than 14 bar (since the opening of the solenoid valve at the reduction unit is permitted for pressure values above this figure).
• If the high pressure parameter is correct, replace the reduction unit.
