Fail-safe

•  PCM restricts fuel pressure. (low pressure side).

•  PCM restricts fuel pressure. (high pressure side).

•  PCM restricts engine torque./Limits the maximum engine speed.

•  Inhibits the DENOx/DESOx control.

•  Inhibits the diesel particulate filter regeneration control.

•  Inhibits the EGR control.

•  Inhibits engine-stop by operating the i-stop function.

Possible cause

•  Fuel filter clogging

•  Fuel pressure relief valve malfunction

•  Suction control valve malfunction

•  Fuel pressure sensor malfunction

•  Erroneous piping (poor connection) of fuel pipe

•  Fuel leakage or clogging in fuel line

•  Supply pump malfunction
