SCR Inducement Override Renewal Required E1598 (2)
Engine Emissions Operator Inducement Emergency Override Renewal Required This code indicates that the Inducement Override has been activated. 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 a Cat dealer through Cat® Electronic Technician (ET) 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.Refer to Special Instructions, REHS9572 for additional information on this feature.
