5 JANUARY 2020 UPDATE
There is no longer an eService case required for ANY STEP of the process below.
A case should ONLY BE OPENED if further assistance is required to complete
diagnosis.
If test results determine an SCR replacement is required, A CASE IS NOT
REQUIRED TO ORDER A REPLACEMENT.
Cases submitted solely to request approval to replace an SCR WILL BE
REFUSED.
PRIOR TO PROCEEDING
Review open campaigns for the vehicle and ensure that it is NOT listed for Recalls EC0020a,
EC0022a, EC0022b, or EC0022c.
IF THE CAMPAIGN APPLIES TO THE VEHICLE:
• No diagnostics are necessary.
• No eService case is necessary.
Follow the recall instructions if the vehicle is listed. This solution should only be utilized if the
vehicle is not included in any of the recalls.
CASES AND DIAGNOSTIC TIME REQUESTS OPENED FOR CHASSIS AFFECTED BY
ONE OF THE ABOVE RECALLS WILL BE REFUSED.
If this solution is being reviewed for P225E-00, solution K15560422 must be
utilized FIRST, and this solution should only be followed if the NOx sensors are
determined to be functioning properly. The tests performed in K15560422 do not
need to be duplicated for this solution.
The following checklist should be used for diagnosis of P20EE or P103C on GHG17
chassis instead of Guided Diagnostics.
DO NOT REPLACE ANY PARTS UNTIL ALL ACTIVITIES LISTED IN THIS CBR ARE
COMPLETE.
NOTE: The Malfunction Indicator Lamp ( MIL ) may still be lit even if P20EE shows inactive on a DTC
Readout.
I. Vehicle Emissions Level
Review the vehicle emissions level
• Details can be found in the Product Details box on the Product tab in PTT as seen below:
• If the vehicle is US17+OBD16 or US17+OBD18:
- Perform Sections II and III below.
II. Vehicle History
- The following information should be obtained prior to beginning diagnosis.
• Is this the chassis's first visit to the dealer for either of these codes?
• Have there been any previous failures or problems that may have caused problems with the Exhaust
Aftertreatment System (EATS)?
Examples:
- Turbocharger failure
- EGR Cooler failure
- Coolant passage through the exhaust
- Excessive fuel through the exhaust (Injector failure, AHI failure)
- DPF failure
- Contaminated DEF
III. Check the DTC Readout
- Are there any other NOx sensor DTCs present?
• P225E and P0422 are very similar to P20EE and should be checked with the same steps below.
• Any other NOx sensor codes may suggest intermittent NOx sensor failure.
- Are there any codes present for other engine components that would indicate an issue contributing to
or causing either P20EE or P103C?
• Examples:
EGR System
Fuel System ( Includes AHI)
Turbocharger/Boost
DPF
Exhaust temperature
IV. Check SCR Efficiency Evaluations
- SCR Efficiency values can be found in Premium Tech Tool ( PTT ) Operation 2589-08-03-05
Aftertreatment Selective Catalytic Reduction (SCR) System.
• The last five efficiency evaluations are displayed as shown in the screenshot above.
If all five tests are below the fault limit, SCR conversion has been poor for an extended amount of
time.
If only one or two are below the fault limit, conversion is only intermittently poor.
- Information on driving conditions when the poor conversion is occurring may provide insight
into the cause of the codes.
V. SCR System Checks
All steps below should be performed to verify proper function of each component.
1. Check DEF quality with a refractometer
2. Physically check for any contamination in the DEF tank
• Examples
- Dirt or Debris
- Coolant
- Water
- Fuel
- Oil
3. Physically inspect the DEF Dosing Valve, Diffuser Pipe, and SCR Inlet for crystallized DEF
• Ensure there is no significant/excessive crystal buildup in any component.
NOTE: A small amount of crystal accumulation is normal.
• If significant accumulation is noted clean it as first step and then ensure that the DEF dosing valve
is correctly installed with all gaskets and clamps positioned properly.
4. Perform DEF Dosing Test 2 to confirm proper function
• Located in Operation 2589-08-03-05 Aftertreatment Selective Catalytic Reduction (SCR) System.
Test B from the first screen of the operation
• Test two is the Small Dosing Test
The test should be run twice and results noted to an accuracy of 2 milliliters
Nominal Volume is 55 mL
- Acceptable range is 55 mL ± 3 mL
5. Check the Main Software part number for the Engine Control Module (EMS).
If vehicle has Turbo-compound system, then do not update EECU SW. Only EECU MSW
23470187 and older have capability to run NOx conversion test on Turbo-compound vehicles.
If vehicle has VGT system, then update EECU MSW to 23766686 or newer.
6. If vehicle has a Turbo-compound System run NOx Conversion, Operation 2549-08-03-03. (only
possible if vehicle still has 23470187 and older EECU MSW).
7. If vehicle has a VGT System run Exhaust After-treatment System Analysis, Operation 2589-08-0318. Make sure to evaluate only NOx sensors and SCR using this test (Please attach pictures emailed).
VI. eService Case
If further assistance is required to complete diagnosis and an eService case is opened, the case MUST
INCLUDE:
1. The vehicle history as described in Section I.
2. A complete DTC Readout from the time of the vehicle's arrival.
3. Screenshots of:
• SCR Efficiency values as shown in Section III
• The NOx Conversion Test as shown in the picture in Section IV.
NOTE: Refer to CBR Solution K52225504 - Methods For Taking A Screenshot
4. A description of findings for each item checked in Section IV, including numerical values for the dosing
tests ("Good", "Okay", "In spec", etc. are not acceptable values).
Internal comments (BO)
For OBD2019 and Newer vehicles (Truck MY2020+), there is a new CBR.
GHG2017 and OBD2018 vehicles have Exhaust Aftertreatment System Analysis Test
(2589-08-03-18), which helps evaluate NOx sensors, DEF dosing valve and SCR in one
~30 minute test with wk1945+ EECU MSW (P/N 2376686 or newer) releases.
We do not have capability to run either NOx conversion or EATS Diagnostics Test
(2589-08-03-18) on Turbocompound Vehicles.

** SOLUTION **
Cause
Many different situations, eService activities or otherwise, may necessitate taking
screenshots, or screen captures, of operations or information in PTT or other programs
Solution
Overview
There are a variety of reasons a screenshot may be needed for review. Diagnostic Trouble Code
Readouts, PTT errors, product or control unit information, diagnostic test results, steps and
messages, and oscilloscope readings name a few.
There are tools available to capture a screenshot, and Windows itself also has the ability to copy a
screenshot to the clipboard without launching a program. This solution will cover the two methods
that can be used on most every computer. If there is other imaging software installed on a
computer that allows screen captures (Snagit, Jing, and FastStone Capture are a few examples), the
software instructions will need to be followed.
Procedure
I. Using The Windows Snipping Tool
Computers running Windows XP or newer ( Windows 7, Windows 8, Windows 10) have the
Snipping Tool utility installed as part of the Windows software package. The Snipping Tool allows
shots to be taken of specific parts of the screen, speeding the process of capturing and saving a
screenshot.
For Windows XP, Windows 7, and Windows 10:
1. Click on the Start Menu, then mouse over or click on All Programs:
2. Scroll through the list of programs and find the Accessories folder:
3. Click on the Accessories folder, then find the Snipping Tool. Click to open the program.
For Windows 8:
1. Click the Start button to bring up the Start Screen
2. Click the Search button (magnifying glass) in the upper right-hand corner of the screen
3. Type "Snipping" into the search bar. Click on Snipping Tool to open the program
For all Windows versions:
4. The Snipping Tool will open ready to capture a shot. The cursor should change to a cross icon.
If the capture doesn't start automatically, click the New button in the Snipping Tool Window.
4a. Move the cursor to where one corner of the screenshot should be. Click and hold the left
mouse button, then drag the mouse to the opposite corner of the desired shot:
4b. When the left mouse button is released, Snipping Tool will capture the highlighted area and
open it in a preview window:
5. If a shot of a complete window is needed, click the dropdown icon (down arrow) next to the
New button in the Snipping Tool and select Window Snip. Clicking once on the desired window to
copy will open a screenshot of the full window in the preview pane:
6. Click on the Save (Disk) icon in the preview window. Save the file to desktop or a folder where
it can be located. Attach the file to the eService case as needed.
II. Using The Print Screen Key
1. If the screenshot will be of a specific window, make sure the window is maximized first.
2. To capture a screenshot of the full screen, press the Print Screen key on the keyboard. NOTE: M
any laptops have Print Screen sharing a key with another function. It may be necessary to hold the
Function key (Usually marked as Fn) as Print Screen is pressed
Wired keyboard
Laptop keyboard
2a. If taking a shot of a specific window, holding the Alt key and pressing Print Screen
(Alt+Fn+Print Screen on a laptop) will only capture the contents of the currently selected window
Wired keyboard
Laptop keyboard
3. Open MS Paint
• For Windows XP and Windows 7 Paint is located in the Accessories folder of the Start
menu, follow the above steps for locating Snipping Tool
• For Windows 8 Follow the steps for the Snipping Tool above to go to the Search box on
the Start screen. Search for Paint
4. With Paint open, press either Ctrl+V on the keyboard to paste the screenshot, click the Paste
button in the upper left-hand corner of the screen (Windows 7), or select Paste from the Edit menu
at the top of the screen (Windows XP). The screenshot will appear in the drawing area.
5. Save the screenshot to Desktop or another folder where it can be easily located. Attach it to the
eService case as needed.
