85 OPERATING THE ENGINE
A
The limited engine output level:
Lv.1 (Level 1): Within 50% of max torque and 60% of
engine speed.
Lv.2 (Level 2): Within engine near idling speed.
A
After an error has occurred, it may be necessary for
the engine output to become limited to Lv.2 (Level 2).
Depending on trouble spots and contents, the
indicator-prompted warnings and the engine output
limits and timings may vary accordingly.
The SCR warning status (from 1 to 3) represents the
severity order of the engine output limitation. If the
SCR system experiences abnormalities, an error code
will be displayed, and it may be necessary to limit the
engine output to Idle Status (Lv.2: Level 2).
(e.g. When a P204F (FMI 1, SPN 1761) error code is
displayed, the engine output changes from
unrestricted to Lv.2 limited.)
A
Points after taking measures.
After the engine has stopped and the DEF/AdBlue®
has drained, if the amount that was refilled is less than
the pre-drain amount, the SCR system may
experience a malfunction. (P20F5 (FMI 15, SPN 4350)
error code is displayed)
When the error occurs, turn the key switch to OFF,
wait for the SCR system to complete the purge
process (this may take several minutes) and then turn
the key switch to ON again in order to clear the SCR
system malfunction.
A When there is a shortage of DEF/AdBlue®, when it
has been refilled with a poor-quality product, or when
there is an abnormality in the SCR system, the Auto
and Parked Regeneration for Diesel Particulate Filter
(DPF) may not function.
