TECHNICAL SERVICE BULLETIN: DATA COLLECTION: EXTRACT CALIFORNIA EMISSIONS DATA FROM ECU (DC24) - 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, KDS screenshots will allow the capture of relevant parameters. Note that a âÂÂWeb Basedâ KDS IUMPR Data Collection procedure is outlined.
