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 via mail-out, website update or ET Blast. 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 lists known OBD II testability issues.

  • Table 2 lists vehicles that currently cannot be OBD II tested. The test analyzer automatically bypasses the OBD II test for these vehicles. However, if the analyzer prompts for an OBD II test for a vehicle listed in table 2, 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.

Note: 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.

Action

Audi and Volkswagen

1996- 2002

All models with non-OEM stereos

If the OEM stereo has been replaced with an aftermarket stereo, these vehicles may not communicate with the analyzer and/or OBD code scanner and may cause severe damage to the analyzer/scanner. For more information, see VW Technical service bulletin 02- 03 dated June 10, 2002.

BAR recommends that you check with your analyzer/scan tool manufacturer to determine whether or not your analyzer/scan tool has complete current/voltage override protection. Override protection will protect the test equipment in cases where aftermarket installations cause over current conditions. BAR’s June 22, 2002 ET Blast provides a method of checking for high voltage conditions using a test light. An alternative is to send all 96-newer VW/Audis with non-OEM radio installations to a VW/Audi dealership for verification of proper OBD function.

Chrysler

1996

Cirrus, Concorde, LHS, Sebring, Sebring Convertible

All monitors reset to “incomplete” upon every ignition key-off.

Determine if Recall Campaign #678 (9/96) has been performed; if not, refer to dealer. TSB 18-005-01 applies to non- California certified vehicles, and may be performed at no cost, even if warranty is expired.

Dodge

1996

Avenger Intrepid Stratus Neon

All monitors reset to “incomplete” upon every ignition key-off

Determine if Recall Campaign #678 (9/96) has been performed; if not, refer to dealer. TSB 18-005-01 applies to non- California certified vehicles, and may be performed at no cost, even if warranty is expired.

Dodge

1996

All 1996 Dodge Stealth models with 3.0L V6 engines

All monitors reset to “incomplete” upon ignition key-off if all monitors set to “complete” prior to ignition off.

Via the vehicle look-up process, the test analyzer automatically ignores monitor status; the monitors are not used for pass/fail decisions. No action on your part necessary.
