## NHTSA's summary

TSB: DATA COLLECTION: EXTRACT CALIFORNIA EMISSIONS DATA FROM ECU \(DC16\) \- This bulletin provides information related to extracting ?in use performance tracking? emissions data from the Engine Control Unit \(ECU\) of certain vehicles sold in California. The California Air Resources Board \(CARB\) requires the emissions data from vehicles with a minimum of 3,000 accumulated miles without reprogramming or resetting. To facilitate collection of this data at the dealer level, GDS/KDS screenshots will allow the capture of relevant parameters.
