Activate ECU dialogue

The ECU will reject the activation key, if it is for a different ECU. The Fault code “SPN 520230 FMI 31 Engine specification mismatch” will stay active, if the activation key is for a different engine specification than the software in the ECU.

6.4.3. ECU activation removal procedure

Pressing the Deactivate ECU button removes the activation from the connected ECU. Now the engine cannot be run at full power. Use this function with a broken ECU before replacing it with a new one.

6.4.4. Specification Mismatch Override

Temporarily override a fault code that occurs when ECU is not properly activated. You can view remaining override time by hovering with your mouse cursor over information icon next to active errors counter on the status bar.
