Tampering/Dosing Interruption
The Emissions System Malfunction lamp will
illuminate for a fault resulting from SCR system
tampering or an SCR system fault. If the fault is the
result of system tampering, a first occurrence will
result in a level 1 inducement for a duration of 2.5
hours. Repeat occurrences will result in a level 1
inducement duration of 5 minutes.
If a fault condition exists for the entire duration of
inducement level 1, the strategy advances to
inducement level 2. For a fault resulting from SCR
system tampering or an SCR system fault, the
Emissions System Malfunction lamp will flash.
The duration for a level 2 inducement is always 70
minutes for the first occurrence. Repeat occurrences
will result in a level 2 inducement duration of 5
minutes.
If a fault condition exists for the entire duration of
inducement level 2, the strategy advances to
inducement level 3. The Emissions System
Malfunction lamp will flash and the Shutdown lamp
will be on. The engine will be restricted to low idle or
will stop. After the final inducement, the keyswitch
can be cycled once which will allow 20 minutes of
engine run time with full torque. After 20 minutes, the
engine will allow idle only or will stop until the fault
has been resolved. The override can only be used
once.
The system must be fault-free for 40 hours before the
system resets to zero. If the fault is intermittent and
returns within 40 hours, the repeat inducement
timings will be triggered.
