APPENDIX J
Smog Check OBD II Reference (Testability Issues)
Appendix J provides information and test instructions about known OBD II functional test difficulties. Technicians must familiarize themselves with the information contained in this
Appendix and follow the specified test instructions when conducting a Smog Check inspection on any vehicle listed.
Please watch for Appendix J updates on the Smog Check website or via ET Blasts. If other problems or solutions arise concerning the testing of OBD II vehicles, BAR will provide updated information advising technicians how to test the affected vehicles.
•
Table 1 - 1a lists known OBD II testability issues.
•
Table 2 lists CAN equipped vehicles that currently cannot be OBD II tested. The
EIS should automatically bypass the OBD II test for CAN equipped vehicles.
However, if the EIS prompts for an OBD II test, bypass the test by answering
“No” to the OBD II functional test prompt. Unless otherwise instructed by BAR, do not answer “No” to bypass the OBD II functional test for any other OBD II equipped vehicles.
In addition to the vehicles listed in Table 2, all vehicles one model-year old and newer are excepted from the OBD II functional test. With each new calendar year, the exceptions change accordingly. For example: In 2007, all 2006 modelyear and newer vehicles are excepted from the OBD II functional test. In 2008, the 2006 model-year vehicles are subject to the OBD II test and the exceptions change to 2007 model-year and newer.
Note: Once the BAR-97 EIS incorporates CAN communication protocol, these vehicles will become testable.
To ensure that any special test processes are appropriately applied, always select vehicle information (make, model, engine size, etc.) from the BAR-97 inspection menus.
