Parked Regeneration
1. Connect DiagnosticLink ®.
2. Turn the ignition ON (key ON, engine OFF).
3. Was another emission component-related fault code repaired prior to this step?
a. Yes; perform a parked regeneration and recheck for the fault code. If the fault code returns, Go to step 4.
b. No; Go to step 4.
4. Check for other fault codes. Are there any air management system (ITV, IMP, IAT, turbocharger etc.) fault codes
present?
a. Yes; diagnose the other fault codes first.
b. No; Go to step 5.
5. Are there any Exhaust Gas Recirculation (EGR) system fault codes present?
a. Yes; diagnose the other fault codes first.
b. No; Go to step 6.
6. Are there any other NOx sensor fault codes present?
a. Yes; diagnose the other fault codes first.
b. No; Go to step 7.
7. Are there any fault codes for the DEF doser, DEF pump, or DEF air valve present?
a. Yes; diagnose the other fault codes first.
b. No; Go to step 8.
8. Turn the ignition OFF.

"Checking Diesel Exhaust Fluid Quality". Is DEF percentage between 28% and 36%?
a. Yes; Go to step 10.
b. No; flush the DEF system. Refer to section "Flushing of the Diesel Exhaust Fluid System". Verify repair.

13. Disconnect the DEF dosing valve electrical connector.
WARNING: ENGINE EXHAUST
To avoid injury from inhaling engine exhaust, always operate the engine in a well-ventilated area.
Engine exhaust is toxic.
WARNING: HOT EXHAUST
During parked regeneration the exhaust gases will be extremely HOT and could cause a fire if
directed at combustible materials. The vehicle must be parked outside.
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.
14. Start the engine.
15. Run the EPA10 Perform Performance Check - Low Temperature ATD procedure to check the NOx sensors. Refer to
section "EPA10 Perform Performance Check - Low Temperature ATD". Are the NOx inlet sensor and outlet NOx
sensor readings within 50 ppm/15% of each other?
a. Yes; Go to step 17.
b. No; replace the outlet NOx sensor. Go to step 16.
16. Run the EPA10 Perform Performance Check - Low Temperature ATD procedure to validate the NOx sensors are
reading correctly. Refer to section "EPA10 Perform Performance Check - Low Temperature ATD". Are the NOx inlet
sensor and outlet NOx sensor readings within 50 ppm/15% of each other?
a. Yes; Go to step 17.
b. No; replace the intlet NOx sensor. Go to step 17.
17. Reconnect the DEF dosing valve electrical connector.
18. Perform a parked regeneration while monitoring the NOx efficiency. Is the NOx efficiency above 70%?
a. Yes; clear codes and release the vehicle.
b. No; Go to step 19.
19. Review the last 7 minutes of the parked regeneration log file; was the SCR inlet temperature within 65°C (150°F) of
the SCR outlet temperature?
a. Yes; Go to step 20.
b. No; replace the ATD.
20. Review the parked regeneration log file. Is the DOC inlet pressure greater than 2.9 psi throughout the parked
regeneration?
a. Yes; replace the ATD.
b. No; Go to step 21.
21. Perform the DOC Face Plug Cleaning procedure to unplug the DOCs. Refer to section "EPA10 Diesel Oxidation
Catalyst Face Cleaning".
