Case IH 17519 – Engine Control Module (ECM): Inducement Lockout / Severe Derate

An emissions-related fault has occurred multiple times, causing the engine control software to enforce a maximum inducement (engine derate or idle-lock) to prevent operation without a functioning emissions system.

1. 1

   Read active faults using the Electronic Service Tool (EST) to identify primary faults in the DEF/AdBlue or Exhaust Gas systems (Code 17519 is a secondary consequence of these).

2. 2

   Inspect exhaust gas temperature sensors, upstream oxidation catalyst sensors, and EGR sensors for physical damage, loose mounting, or soot accumulation.

3. 3

   Inspect sensor harnesses for short-to-ground conditions or open circuits, and verify the ECM is receiving proper and stable battery voltage.

4. 4

   Verify that the DEF tank is full, the fluid is not degraded or contaminated, and the DEF quality sensor is communicating properly on the CAN bus.

1. 1

   Repair the Root Cause

   Follow the appropriate diagnostic procedure to resolve the specific active emissions fault (e.g., replace the faulty exhaust gas sensor or DEF component).

2. 2

   Connect the EST

   Plug the Electronic Service Tool into the machine's diagnostic port and turn the ignition ON.

3. 3

   Navigate to Configurations

   In the EST software, go to the Configuration menu (often found under the Selective Catalytic Reduction (SCR) exhaust treatment section).

4. 4

   Select the Reset Option

   Select the screen for "Engine Restart Counter Reset / Unlock Inducement".

5. 5

   Execute the Reset

   Click on "CONFIGURE SELECTED ITEM", and then click the button labeled "RESET ENGINE RESTART COUNTER / UNLOCK INDUCEMENT".

6. 6

   Verification Test

   Perform the "SCR Fault Repair Verification Test" using the EST to ensure the system recognizes the repair.

7. 7

   Clear Codes

   Once the verification test passes, the inducement lock will be lifted. Clear any remaining inactive fault codes and return the machine to service.
