Mack OBD / OBD2 Codes

2013 Mack OBD2 Codes

Mack trucks newer than 2013 have OBD2 code support. Please see the table below for mfg specific OBD2 codes as well as the generic code pages on this website for non-Mack specific codes.  Mack is a brand of Volvo with shared engine design.

2010 Mack OBD Codes

Note: The use of a scan tool is necessary to perform diagnostic work as well as clearing of any diagnostic trouble codes (DTCs). DTC(s) can no longer be cleared using the vehicles instrument cluster digital display and stalk switch control.
