Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe® Online for applicable fixes to the calibration stored in the ECM.
This fault code is activated when one of the OEM defined inputs has exceeded a calibratible limit. The triggers for shutdown are OEM dependent.
1)Replace the OEM harness.
2)If necessary, recalibrate the ECM.
