6. Push the quick connect fitting coupling in the ON direction, squeeze the holding clip lugs on either side of the
connector and pull to disconnect the DEF supply line from the dosing valve. Cover the DEF line with a plastic
bag and secure the bag with a tie wrap to prevent spillage on nearby components. Note: If the DEF line will
remain open for an extended period of time, seal the opening to prevent crystallization of fluid in the line.

9. Remove and discard the aftertreatment DEF dosing valve fasteners. Remove the aftertreatment DEF dosing
valve from the aftertreatment DPF. Note: If the dosing valve will be reused, use plug kit 21376772 to cap the
coolant and DEF valve fittings to prevent contamination and crystallization of DEF in the valve.

1. Fasteners
2. Dosing Valve
10. Remove and discard the aftertreatment DEF dosing valve gasket.
Installation
1. Make sure that the mounting surface on the DPF outlet pipe is clean.
2. Position a new gasket on the aftertreatment DEF dosing valve and install the valve on the aftertreatment DPF
using new fasteners. Tighten the fasteners to specification, refer to Function Group 20, Specifications.
3. Remove the protective covering and reconnect the electrical connector to the aftertreatment DEF dosing valve.
4. Verify the connector is clean and shows no signs of damage. Push the fitting onto the valve until it stops to
reconnect the coolant lines to the aftertreatment DEF dosing valve. Pull the fitting in the OFF direction to ensure
the connector is locked in place.
5. Remove the protective covering and verify the connector is clean and shows no signs of damage. Push the fitting
onto the valve until it stops to reconnect the DEF supply line to the aftertreatment DEF dosing valve. Pull the
fitting in the OFF direction to ensure the connector is locked in place.
6. Install all previously removed cables to the ground (negative) battery terminals.
7. Connect VCADS and clear any codes. Run SCR Dosing Test 1 in VCADS to fill the line and dosing valve with
DEF. Check for any DEF leaks at the connection.
8. Clean any residual fluids from the dosing valve and lines. Start the engine and check for coolant leaks at the
dosing valve. Run the DEF Tank Heating Valve Activation Test in VCADS to purge air from the coolant lines.
Ensure coolant is at the correct level after test. Clear any codes as required. Replenish the engine coolant level
as required.
9. Install rear top access panel.
10. Close rear engine service doors.
Additional Resources
These repairs are the most likely fix for the identified fault, if this does not fix the issue, Tech Tool will need to be
used for more detailed diagnostics. If filing a warranty claim, please include the ASIST case number.
