Indicator Lamp (MIL) - US17+OBD16 And US17+OBD18 (GHG17) Emissions
(Common Rail Fuel System) - Commonly Model Years 2018 And 2019
Cause
US17 chassis may generate code P0420, with Guided Diagnostics (GD) determining
there is No Fault Found (NFF)
Solution
Verify the chassis emissions level
- Details can be found in the Product Details box on the Product tab in PTT as seen
below:
Review the Detailed Status Information for the relevant code on the DTC
Readout.
Once the chassis is confirmed to be US17+OBD16 or US17+OBD18:
- Software improvements have been released to address this code.
- Refer to FSB 284-067 Engine Control Module (EMS) and Aftertreatment Control
Module (ACM), Reprogramming.
• The bulletin can be found under the Service tab in Impact by searching for
either the FSB number, or by reviewing the articles under Function Group 284.
• If the article does not appear when searched with either VIN or Chassis
information entered, search by model:
1. Clear any chassis information from the Search box.
2. Select or enter the applicable model.
3. Make sure Title is selected in the Search By field. Enter "FSB 284067" in the text entry field.
4. Press the Search button. The operation will appear in the results
window.
5. Mutiple article choices will appear. Find the Operation for the correct
Chassis.
Note: It is possible that more than one choice will have the same
title (as shown below). Despite having the same title, the Operations
are different and should be reviewed to locate the correct procedure.
If software is current according to the bulletin, the code should only be diagnosed
if the Confirmed Status is True, as shown above. If status is False, the code should be
cleared and the vehicle released.
If other symptoms or related codes are present, normal diagnostics will need to
be performed to determine the cause.
