SCR Inducement Override Re-
newal Required
This code indicates that the Inducement Override has been activated.
The code is logged.
Follow the troubleshooting procedure to identify the root cause of the fault.
When an emergency situation occurs, initial
activation of the override is allowed without input
from Caterpillar
™
. Prior to activation, the operator will
be notified of the following on display :
“EMERGENCY USE ONLY. SEE OWNERS
MANUAL. PENALTIES APPLY FOR MISUSE” .
Upon activation, the check engine, and action lamps
will also illuminate to alert the operator that the
override is active. A code will also become active
indicating that the engine emission operator
inducement emergency override is active. The code
will remain active until the override is reset. The
override must be paused by the operator if the
emergency ends before the 120 hours of override
operation has expired. While paused, the equipment
will be subject to inducements (derates). The
override may be reactivated if an emergency
situation returns. After 120 hours of override use the
override will expire, and the equipment will be subject
to inducements. Upon activation, the check engine
and action lamps will continue to be illuminated until
the override is reset. If the override has expired, the
dealer will need to reset the override to use the
override again. The code indicating that the engine
emission operator inducement emergency override is
active, will be cleared when the override is reset.
Resetting the override is the only way to clear the
code.
The override needs to be reset by an authorized
dealer or distributor through the electronic service
tool whenever the override has expired. The override
cannot be used again until the override is reset. The
warning lamp will continue to be illuminated until the
override is reset. The override may be reset at any
point after the initial activation.
