Official summary
Supersedes Technical Service Bulletin Group 01 number 13-35 dated October 8, 2013. During reset of the service reminder, the message ?AIR system - action required - observe test plan? appears on the ODIS tester. MIL is not illuminated. Under certain driving conditions, the secondary air ports in the cylinder head can accumulate carbon over time, causing a restriction. The ODIS tester can identify the state of the restriction, and will request that the system is cleaned in order to prevent the MIL from illuminating.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
