!Description
|-
|12
|'''Power Take-Off Speed Adjust''' (PTOSA) - System on for more than 2 seconds with more than a full PTOSA speed request.
|-
|13
|'''Coolant Level Loq''' - System running for 2 seconds with a low sensor output (voltage).
|-
|14
|'''Low Oil Temperature''' - Engine running for 8 minutes with a very cold (less than 0° C) oil temperature indication.
|-
|15
|'''High Oil Temperature''' - Engine running for 2 seconds with a very hot (greater than 170° C) oil temperature indication.
|-
|16
|'''Coolant Level High'''- System running for 2 seconds with a high sensor output.
|-
|21
|'''High Throttle Position''' - System running for 2 seconds with too high a throttle position indicated.
|-
|22
|'''Low Throttle Position''' - System running for 2 seconds with too low a throttle position indicated.
|-
|25
|'''No Codes''' - No fault codes have been detected by DDEC since the last time codes were cleared.
|-
|26
|'''Power Control Switch''' - Indicates that the power control switch has been used. This switch, when thrown, turns on both the "Stop Engine" and "Check Engine" lights. In addition, the engine will begin to "power down" (and eventually shut down) if the engine protection system is equipped with the optional shut-down feature.
|-
|311 to 318
|'''Response Time Too Long''' - The response time of the injector was longer than the maximum limit or the injector never responded at all. Oil temperature must be greater than 20 degrees C and battery voltage must be between 11 and 16 volts to log this code.
|-
|321 to 328
|'''Response Time Too Short''' - The response time of the injector was shorter than the minimum limit. Oil temperature must be greater than 20 degrees C and battery voltage must be between 11 and 16 volts to log this code.
|-
|33
|'''High Turbo Boost Pressure''' - Engine idling (at less than 1000 RPM} for 2 seconds with a very high (greater than 197 KPa) turbo boost indication. Also, pulsewidth must be less than 10 degrees to log this code.
|-
|34
|'''Low Turbo Boost Pressure''' - Engine running for 2 seconds (at greater than 300 RPM) with a very low {less than 19 KPa) turbo boost indication.
|-
|35
|'''High Oil Pressure -''' Engine running for 2 seconds with a very high (greater than 422 KPa} oil pressure indication. Must also have greater than 50 degrees C oil temperature and be at less than 1300 RPM to log this code.
|-
|36
|'''Low Oil Pressure''' - Engine running for 2 seconds with a very low (less than O KPa) oil pressure indication. Must also have greater than 50 degrees oil temperature and greater than 300 RPM to log this code.
|-
|41
|'''Timing Reference Sensor Pulses Fault''' - The number of TRS pulses received per revolution was incorrect or completely missing. One pulse per cylinder per revolution 1s required.
|-
|42
|'''Synchronous Pulses Fault''' - Did not receive an SRS pulse on every firing of the #1 cylinder.
|-
|43
|'''Low Coolant''' - System running with low coolant for 7 seconds. This fault will cause both the "Stop Engine" and "Check Engine" light to turn on, and will power down (and eventually shut down} the engine if the engine protection system is equipped with the shutdown feature.
|-
|44
|'''Oil Over Temperature''' - Oil temperature over a maximum limit (about 128 degrees C} for 7 seconds. Both the "Stop Engine" and "Check Engine" lights will turn on and will power down (and eventually shutdown) the engine if the engine protection system is equipped with the shutdown feature. (NOTE: If the oil temperature 1s between 121 and 128 degrees C, no code will be logged, but the "Check Engine" light will come on after 2 seconds and power down the engine if equipped with the power down feature (but won' t power it down as severely as with the 128 degrees C limit.)
|-
|45
|'''Low Oil Pressure''' - Engine running wf th the 011 pressure less than the limit (different limits at different RPM's) for 7 seconds. This fault will cause both the "Stop Engine<nowiki>''</nowiki> and "Check Engine" light to turn on, and will power down (and eventually shutdown) the engine if the engine protection system is equipped with the shutdown feature.
