Verify the chassis emissions level and ensure that the vehicle is within the
applicable range for this solution.

below:
Review the Detailed Status Information for the relevant code on the DTC Readout.
A. Software improvements have been made that address this DTC:
1. Service Program SP 284-067 Engine Control Module (ECM) and Aftertreatment
Control Module (ACM), Software Updates was released July 2018. This service
program should appear under the Campaigns section of the Product screen of
Premium Tech Tool (PTT) when first connecting to the vehicle
- The Service Program document can be found on the dealer Volvo Trucks
eMedia.
• Note: There will be a prompt to sign in to the Trucks Dealer Portal site if
necessary.
• Searching for 284-067 will return a link to the bulletin.
2. If there are no other concerns, release the vehicle after the campaign is completed.
B. If the Service Program does not apply to the chassis or there are possible related
symptoms:
1. Check the Main Software (MSW) part number for the Engine Control Module
(EMS).
• If the software part number is less than 23033425, update the EMS software.
• NOTE: Software updates will not resolve physical symptoms. If there are any
concerns with operation, appropriate diagnostics will need to be performed.
2. Make sure to inspect the crankcase ventilation (CCV) system for any leaks or
disconnected components. Repair any concerns located.
3. Make sure that engine oil is not increasing with time. If engine oil is rising, the
cause should be diagnosed independently of P04DB.
C. If software is current and there are no physical issues located:
1. Clear the code and release the vehicle.
