| Particulate Matter Sensor Service Regeneration | This device control is used to force a particulate matter sensor measurement cycle, consisting of a particulate sensor probe regeneration and subsequent soot accumulation measurement. The system will return to normal control after one measurement cycle is successfully completed. One full measurement cycle can take 15 minutes or more to complete depending up the particulate filter state of health. |
| Pilot Injection Balance Procedure | This device control disables each fuel injector pilot injection. Device Control can be changed at any engine or vehicle speed. The device control will not change unless changed or cancelled by the scan tool. |
| Positive Crankcase Ventilation Heater | This device control is used to turn the crankcase ventilation heater output ON or OFF. |
| Programming History | This device control is used to view the history buffer entries for the primary calibration part in the controller. |
| Reductant Fluid Quality Test | This device control is used to force a Selective Catalyst Reduction (SCR) Service Quality Check. |
| Reductant Fluid Tank Level Reset | This device control is used to Reset the Reductant Fluid Tank Level. |
| Reductant Heater 1 | This device control is used to override the state of the Reductant Heater 1. The scan tool disables the test when the following control limits are exceeded.
|
| Reductant Heater 2 | This device control is used to override the state of the Reductant Heater 2. |
| Reductant Heater 3 | This device control is used to override the state of the Reductant Heater 3. |
| Reductant Injection Quantity Test | This device control is used to inject a specific amount of reductant from the reductant injector. A system purge will be required once the test is complete. |
| Reductant Injector | This device control is used to verify functionality of the NOx Reductant Injector by allowing NOx Reductant Injector output to be commanded to a specific duty cycle. |
| Reductant Injector Reset | This device control is used to reset the Reductant Injector variables after the Injector is replaced. |
| Reductant Pump | This device control is used to verify functionality of the NOx Reductant Pump by allowing NOx Reductant Pump output to be commanded to a specific duty cycle. |
| Reductant Purge | This device control is used to purge the reductant lines of fluid. |
| Reductant Purge Valve | This device control is used to command the state of the NOx Reductant Line Purge valve. |
| Reductant System Data Reset | This device control is used to reset the ECM data in case of a replacement. |
| Reductant System Leak Test | This device control is used to pressurize the reductant system in order to perform a visual inspection for leaks. A system purge will be required once the test is complete. |
| Reductant System Malfunction Warning Service Bay Test | This device control triggers the Selective Catalytic Reduction (SCR) Tamper Service Bay Test. |
| Reductant System Reset | This device control is used to reset the Reductant Module data in case of a replacement. |
| Remote Vehicle Start Disable History Reset | This device control is used to trigger the reset of the last eight reasons that powertrain has disabled remote vehicle start (RVS). |
| Starter Relay | This device control is used to override the state of the Starter Relay output. Fuel is disabled to prevent the engine from starting if the starter relay output is commanded On. |
| Total Fuel Consumed Reset | This device control contains the after treatment related data parameter that needs to be transferred in case of an ECM replacement. |
| Turbocharger Learn | This device control is used when the Turbocharger assembly, Vane position control solenoid valve, Vane position sensor is replaced or repairs that disturb turbocharger components. |
| Turbocharger Vane Position | This device control adjusts the turbocharger vane position in 5 percent increments from 0-100 percent. The device control will be aborted if engine speed is above idle or if the coolant temperature is too cold. |
| Turbocharger Vane Position Solenoid Valve | This device control cycles the turbocharger vane position solenoid to 100 percent boost and back to 0 percent boost. The device control is limited to engine speeds less than 1, 500 RPM and will be disabled if DTC P0047 or P0048 are set. |
| Wait to Start Indicator | This device control is used to turn the Glow Plug (Wait to start) Lamp ON/OFF. |
