26 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 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 refueled is less than the pre-
drain amount, the SCR system may experience a malfunction.(P20F5 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 The 40 hours warning record.
(1) Basically Warning and/or inducement reduction cancel when the fault location is repaired.
(2) However, if it detects any fault within 40 hours of the restoration, it soon becomes back to the previous failure and
the timer restarts counting down.
(3) The 40 hours warning record will be reset if any fault has not been detected over 40 hours from the repair.
If a fault would be detected after the 40 hours warning record reset, then the new countdown will be stated.
