Diagnostic Trouble Code ( DTC ) P2698, Diagnostic And Repair Information - US14+O
BD15 And US14+OBD16 (Commonly Model Years 2016 And 2017)
Cause
Solution
Chassis may generate DTC P2698 with no physical symptoms present.
DO NOT replace any components for this code unless diagnostic steps in this article
reveal that a specific component is the issue.
- Verify the chassis emissions level and ensure that the vehicle is within the applicable
range for this solution.
- 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.
• If Confirmed DTC is TRUE: Proceed with diagnostics
• If Confirmed DTC is FALSE: Disregard and focus on other symptoms or DTCs relevant
to the complaint.
- P2698 typically logs with confirmed status for the following reasons:
• Exhaust gas temperatures
• Aftertreatment Hydrocarbon Injector ( AHI, Seventh Injector ) nozzle low flow
• AHI Module function
• Diesel Oxidation Catalyst ( DOC ) function
Diagnosis
Any code pointing specifically to one or more of the components in the above list should
be diagnosed FIRST. P2698 is likely a symptom of these codes, not the source.
1. Check Temperature Sensor readings with the engine and exhaust completely cooled.
- All three temperature readings should be within 5 °F (3 °C) of one another.
2. Start the engine and watch all three temperature sensor readings during warmup.
- Expected behavior is for DOC Inlet ( T1 ) temperature to rise first, followed by
the Diesel Particulate Filter ( DPF ) Inlet ( T2 ), then DPF Outlet ( T3 ).
- Once reaching normal idle from a cold start, temperatures should settle with DOC
Inlet temperature the highest, followed by DPF Inlet, and DPF Outlet the lowest.
3. Check AHI functions using Operation 2545-08-03-02 Exhaust Aftertreatment Diagnostics,
located under the Test tab in Premium Tech Tool ( PTT ).
- Perform Test B and verify correct flow through the 7th Injector nozzle.
- Perform Test D to confirm the AHI module is functioning correctly.
4. If there is no fault found, the code count is low, and there are no other codes present
that could be causing P2698 to log clear the code and release the truck.
5. If the chassis has been in for the same fault in confirmed status previously please
create an eService case.
