When you first receive the alert followed with Engine will derate in 60 minutes, and you know the engine will shut down soon. The first thing to do is to stop your vehicle and do a visual inspection. Better yet, call your service workshop for scanning. Check your DEF tank first and check for any possible contaminants.

When either of these is enabled, the engine will experience a speed or torque derate if the temperature in the exhaust stack of either the Left (A) or Right (B) Bank exceeds the calibrated threshold. Engine shutdown may occur if a derate does not return operating conditions to an acceptable range, as defined by the calibration.
