2 GHG17 Diesel Oxidation Catalyst Face Cleaning

The Diesel Oxidation Catalyst (DOC) Face Plug Cleaning service routine can be run to unclog the front face of the Diesel
Oxidation Catalysts. It can be used on a 1-Box™ emissions package or Two-box option.

Before performing this service routine, the cause of the DOC plugging should be found and corrected. Typical causes are
vehicle duty cycles that are stop-and-go, have excessive idle time, have stationary PTO operation, or have a hardware issue
with the engine or vehicle. Perform the "ATD Checklist" to review these items and correct them before running this service
routine.

The following engine conditions must be met before this routine can be performed:
+ Engine is at base idle speed
NOTICE: Do not run the service routine if the DOC inlet pressure is greater than 20 kPa (2.9 psi). If the pressure

is above that, use the DOC air cleaning tool P/N: W470589239100. Refer to section "Diesel Oxidation Catalyst Air
Cleaning". This is to protect the engine and turbocharger from excessive exhaust temperatures.

This service routine will run for approximately 4 hours and 45 minutes. You MUST remain with the vehicle for the entire
procedure.

If possible and safe to do so, warm up the engine to operating temperature before running the service routine.

To improve the chances of a successful procedure, engine load needs to be as low as possible. Turn off all unnecessary
accessories in the truck such as the air conditioner, extra lighting, PTO, etc. Note that setting the HVAC system on Defrost
typically turns on the air conditioner, so turn off the HVAC system or select a different setting.

Check as follows:

WARNING: PERSONAL INJURY
Diesel engine exhaust and some of its constituents are known to the State of California to cause

cancer, birth defects, and other reproductive harm.

+ Always start and operate an engine in a well ventilated area.
* If operating an engine in an enclosed area, vent the exhaust to the outside.
* Do not modify or tamper with the exhaust system or emission control system.

WARNING: PERSONAL INJURY
To avoid injury before starting and running the engine, ensure the vehicle is parked on a level

surface, parking brake is set, and the wheels are blocked.

41. Start the engine and allow it to idle at base (600 rpm) idle speed.
2. Connect DiagnosticLink 8.3 with Service Pack | (or higher).
3. Navigate to the Actions menu (1) / Aftertreatment (2) / DOC Face Plug Cleaning (3).

6. Read the dialog prompt message in the button left hand corner. Press and hold the regeneration dash switch located on
the dash for five seconds (2). See figure above.
7. When the regeneration dash switch is depressed, the DPF Regen Switch Status Box will turn green.

8. Once the switch has been depressed for five seconds, the engine rpm will ramp up to about 1250 rpm.

9. The Intake Throttle Valve (ITV) (if applicable) and Jake Brake | (PWM13) may begin cycling (temperature
dependent) to raise DOC Inlet Temperature. This will cause engine rpm to fluctuate. The engine will run and sound
abnormal during this transition point but this condition is COMPLETELY NORMAL.

10. After the engine warms up, the ITV (if applicable) should become steady. The Jake Brake 1 (PWM13) will be steady
at 100%. Engine rpm should then become stable about 1250 rpm.

11. Monitor DOC inlet temperature (1). The DOC inlet temperature should be greater than 400°C (750°F). Ambient

temperature will have a large impact on DOC inlet temperature. If it is not above 400°C (750°F), block off part of the

radiator. Be careful that coolant temperature does not go high enough to cause a Check Engine Light. If 400°C

(750°F) DOC inlet temperature is not reached, the service routine will abort. See Figure below. Note the DOC inlet
temperature (1) is too low in this picture.

12. After four hours of run time, the engine rpm will change to 1100 - 1250 rpm (2) and a standard DPF Parked
Regeneration will occur automatically. The Parked Regeneration process will take about 45 minutes.

13. Ifthe DOC inlet pressure (1) see above figure) is within the expected range, the routine will complete. If not, the

service routine will abort.
14. After the DPF Parked Regeneration has completed, the engine will ramp down to 600 rpm to cool down.
15. The service routine is complete when actual engine speed is at 600 rpm (1).
