1. 1

   Allow the module to cool down so the internal temperature drops back into the normal operating range

2. 2

   Cycle the ignition OFF, wait a moment, and then switch it back ON

3. 3

   Check SERDIA Diagnostics and refer to Chapter 2000 Reg. B - EMR troubleshooting plan if further diagnosis is needed

1. 1

   Ensure the tractor has cooled down and the ambient temperature around the ECU is normal.

2. 2

   Switch the ignition OFF, then ON.

3. 3

   If the error reappears despite the temperature being in the normal range, the internal temperature sensor or the board itself has failed.

4. 4

   Replace the ECU EMR2.

   When replacing an EMR2 ECU, the old data record must be saved and flashed/loaded onto the new control unit using the SERDIA diagnostic tool.
