INSPECTION
INSPECTING THE COMMON RAIL
1. INSPECTING THE FLOW DAMPER
(1) Start the engine and change the engine revolution from idling to full
throttle. Use Hino-DX to check the diagnosis code of the "flow damper
operation".
(2) If the diagnosis code of the "flow damper operation" is detected,
replace the relevant injector and inspect it again.
(3) If the same phenomenon occurs even after the injector is replaced,
replace the flow damper with a common rail assembly.
