Check on methane pressure in high pressure circuit

Check 1058A

BIPOWER

Connect the Examiner diagnostic equipment.

Select 'methane gas injection' in the 'Control Unit Test' ambient.

Identify the item 'Methane pressure' under the parameters.

With the engine running, measure the pressure and check that it is above 10 bar with the canisters almost empty and a maximum of 220 bar with the canisters completely full.

It should be remembered that the pressure in the canisters is also affected by the ambient temperature - if the temperature is low, the pressure is less.
