NOTE :
• The limited engine output level:
The text
“Lv.1”
and
“Lv.2”
displayed next to the icon represents 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.
• After an error has occurred, it may be necessary for the engine output to become limited to
“Lv.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”
).
For example, when a
“ENG P-204F”
error code is displayed, the engine output changes from unrestricted to
“Lv.2”
limited.
• 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”
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.
• The time displayed on the lower right of the icon represents the minimum time until the limitation begins.
• 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 returns to the previous failure
and the timer restarts counting down.
