the same time the vehicle is in the workshop for this campaign.

control module (ECM) requires an update to validate and, if necessary, reapply the ECM
software that was installed on these vehicles at the time that they received the Approved
Emissions Modification (USA) / Emissions Modification (Canada). This issue could have an
impact on vehicle tailpipe emissions.
Update the ECM software.
