2 Page 2 of 5 Faults Inactive Brakes Left Drive Axle Sensor Open or Shorted 4-3 SID Inactive Brakes J1939 Retarder 11-2 SID SAE - Forward Rear Drive Axle Temperature - SAE - Rear Rear Drive Axle Temperature - SAE - Transmission Oil Temperature - SAE - Remote Accelerator Pedal Position - Inactive Engine Fuel Pressure Low - Data Valid But Below Normal Operational Range - Moderately Severe Level. OR Fuel Pump Delivery Pressure - Data Valid but Below Normal Level. Low fuel pressure has been detected by the ECM. Inactive Engine Fuel Pressure Low - Data Valid But Below Normal Operational Range - Moderately Severe Level. OR Fuel Pump Delivery Pressure - Data Valid but Below Normal Level. Low fuel pressure has been detected by the ECM. Inactive Engine Crankcase Pressure - Data Erratic, Intermittent, or Incorrect. The ECM has detected that the crankcase pressure signal is not changing with engine operating conditions. Inactive Engine Engine Coolant Temperature - Data Valid but Above Normal Operational Range. Engine coolant temperature signal indicates engine coolant temperature above engine protection warning OR critical limit. Inactive Engine SAE - Engine Coolant Temperature - Special instructions 482 or or 2215 SPN SPN SPN SPN PID SPN SPN or 151 or 2963 SPN PID

3 Page 3 of 5 Inactive Engine Engine Coolant Temperature - Data Valid but Above Normal Operational Range - Least Severe Level. Engine coolant temperature is above the engine coolant temperature engine protection warning limit. Inactive Engine Engine Coolant Temperature - Condition Exists. The EGR valve was closed to reduce engine coolant temperature. Inactive Engine Coolant Level - Data Valid but Below Normal Operational Range - Least OR Moderately Severe Level. Low engine coolant level detected. Inactive Engine Coolant Level Sensor 1 Circuit - Voltage Above Normal, or Shorted to High Source. High signal voltage detected at engine coolant level circuit. Inactive Engine Coolant Level Sensor 1 Circuit - Voltage Below Normal, or Shorted to Low Source. Low signal voltage detected at engine coolant level circuit. Inactive Engine Coolant Level - Data Valid but Below Normal Level. Low engine coolant level detected. Inactive Engine Power Supply Lost With Ignition On - Data Erratic, Intermittent, or Incorrect. Supply voltage to the ECM fell below 6.2 volts momentarily, or the ECM was not allowed to power down correctly (retain battery voltage for 30 seconds after key OFF). Pressure Sensor - Data Erratic, Intermittent, or Incorrect. The aftertreatment diesel particulate filter differential pressure sensor is reading an erratic value at initial key-on or during engine operation. OR EGR Valve Control Circuit - Abnormal Update Rate. No communications or invalid data transfer rate detected on the J1939 datalink between the ECM and the smart EGR valve. Pressure Sensor Circuit - Voltage Below Normal, or Shorted to Low Source. Low signal voltage or open circuit detected at the aftertreatment differential pressure sensor circuit. Inactive Engine SAE - Exhaust Gas Temperature 1 - Data valid but above normal operational range - Most severe level 2963 SPN or or 2448 SPN PID SPN SPN SPN SID or 1893 SID SID SID

Low signal voltage detected at the catalyst inlet sensor circuit. Range - Moderately or Most Severe Level. The aftertreatment diesel particulate filter inlet temperature sensor reading has exceeded the maximum temperature limit or the maximum engine protection temperature limit. aftertreatment diesel particulate filter inlet Inactive Engine Aftertreatment Exhaust Gas Temperature 3 - aftertreatment diesel particulate filter outlet Inactive Engine SAE - Engine Turbocharger 1 Turbine Inlet Temperature - Data valid but above normal operational range - Most severe level Inactive Engine Power Supply Lost With Ignition On - Data Erratic, Intermittent, or Incorrect. Supply voltage to the ECM fell below 6.2 volts momentarily, or the ECM was not allowed to power down correctly (retain battery voltage for 30 seconds after key OFF). Inactive Engine Turbocharger Turbine Inlet Temperature (Calculated) - Data Valid but Above Normal Operational Range - Least Severe Level. Turbocharger turbine inlet temperature has exceeded the engine protection limit. Range - Most Severe Level. Engine exhaust gas temperatures entering the aftertreatment system are above the engine protection limits SID SID or 1969 SID SID SID SID SPN SPN SPN
