vehicles built between January 2018 and July 2020

General Information
Daimler Trucks North America LLC, on behalf of its Detroit Powertrain Division, is initiating Field Service
Campaign D20M8 to modify the vehicles mentioned above with ACM software 7.61.1.0. This software has
been released to improve NOx sensor life. Programming the MCM, ACM, CPC, and TCM to a MINIMUM
of the software and fuel map version listed below will be necessary for compatibility. See 20TS-04 if New
Cascadia CPC501T is not at the software level shown in the table.

The ACM software and fuel maps became effective for all GHG17 & GHG21 DD13, DD15, and DD16
engines, and was released on June 18, 2020. Any GHG17 & GHG21 DD13, DD15, or DD16 Platform
engines in vehicles manufactured between January 2018 and July 2020, running older software and fuel
map version ZGS, will need to have the ACM reprogrammed. Note that some trucks may already have
been reprogrammed and will be excluded from this modification.
Note that the current software and fuel map levels may be higher than the minimum levels shown above.

Corrective Procedure
1. Apply the parking brake, chock the wheels, and perform any other applicable safety steps.
2. You MUST use DiagnosticLink® Professional 8.12 Service Pack 1 (or higher) when
reprogramming. REFERENCE DTNAConnect “My Communications” notice dated 07/24/2020 for
more information on DiagnosticLink® 8.12 Service Pack 1, or 20CSA-10.
3. Begin the process by connecting DiagnosticLink® to the vehicle. Make sure that all the modules
(ACM, CPC, MCM, and if applicable, the TCM) are connected.

4. Make sure the VIN is correct in all modules (ACM, CPC, MCM, and if applicable, the TCM) by
looking at the “Identification” screen in DiagnosticLink®. If the VIN is not correct in all modules,
you can correct the VIN under the Actions drop-down menu in DiagnosticLink® by selecting the
“Check VIN Synchronization” item. Select “Start” from this panel and follow the prompts. You will
be prompted to cycle the key until the routine has completed. When synchronization is complete,
turn the key back on and continue with the download process.

5. On the Identification screen, check the current ACM, MCM, CPC, and TCM (if equipped) software
and fuel map levels. Listed in the table on page 1, are the MINIMUM levels required. See Figure
1 for an example of the Identification screen for the ACM.
a) ACM software 7.61.1.0 and fuel map version ZGS 002

6. Is the software and fuel map ZGS version level for the ACM, MCM, CPC, and TCM (if equipped)
less than, equal to, or higher than the software and fuel map ZGS revision levels listed in the
table on page 1?
The ACM, MCM, CPC, and TCM (if equipped) software and fuel map ZGS version level must
meet the MINIMUM requirements.
a) If less than the minimum software and fuel map ZGS version levels, proceed to step 7.
b) If equal to, or greater than, the minimum software and fuel map ZGS version levels, no
programming is necessary. Proceed to step 12.
