## NHTSA's summary

During reset of the service reminder, the following message appears on the ODIS tester: ?Secondary air injection system \- checking secondary air mass?. 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.
