M A I N T E N A N C E 348 MAINTENANCE SCHEDULES EMISSION CONTROL SYSTEM MAINTENANCE The "Scheduled" maintenance services, listed in bold type on the following pages must be done at the times or mileages specified to assure the continued proper functioning of the emission control system. These, and all other maintenance services included in this manual, should be done to provide best vehicle performance and S reliability. More frequent maintenance may be needed for C vehicles in severe operating conditions such as dusty H areas and very short trip driving. E D U L E S Inspection and service also should be done any time a malfunction is suspected. NOTE: Maintenance, replacement, or repair of the emission control devices and systems on your vehicle may be performed by any automotive repair establishment or individual using any automotive part which has been certified pursuant to U.S. EPA or, in the State of California, California Air Resources Board regulations. 8 EMISSIONS TESTING In some localities, it may be or will become a legal requirement to ensure that all emissions components and systems are functioning properly as a part of the test procedure. The test center accomplishes this by checking the On Board Diagnostic System (OBD) system with an electronic scan tool. If your vehicle has recently been serviced, the OBD system may have been reset to a Љnot readyЉ condition because the OBD system has not had sufficient time since the servicing to reconfirm that emissions components are operating properly. In most cases, a reasonable mix and amount of normal city and highway driving and at least one overnight-off period will be required to prepare your vehicle for this check; however your dealer has the equipment and procedures required to make certain that the OBD system of your vehicle is ready for the required testing.
