Action

Mitsubishi

1996- 2001

Montero, Montero Sport, Diamante, 3000GT, Mirage, Galant, Expo/Expo LRV, and Eclipse models (except 2.0L non--turbo 420A engine models)

Some monitors are difficult to set to “complete.”

Mitsubishi provides recommended drive cycles in its service information to assist technicians to operate monitors. Mitsubishi Technical Service Bulletin #TSB-00-13-005 (incl. drive cycle for 1996- 1997MY affected vehicles only). See service manual for 1998-2001 drive cycles.

Nissan

1996- 1997

All Models

The catalyst and evaporative monitors are difficult to set to “complete.”

Nissan provides recommended drive cycles (drive patterns) in its service information to assist technicians to operate monitors. See Nissan Technical Service Bulletin #NTB98-018c, January 3, 2002.

Plymouth

1996

Breeze Neon

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

A manufacturer recall is in effect. Verify recall has been performed. If not, refer to dealer for the recall.

Saab

1996- 1998

900 (B234i with Motronic 4.1)

All monitors are difficult to set to “complete.”

Saab Service Instruction No. 248 describes the correct drive cycle for completion of the monitors.

Saab

1996- 1998

All Models

The catalyst and evaporative monitors are difficult to set to “complete.”

The Smog Check OBD readiness criteria for this vehicle allow two monitors to be incomplete.

Subaru

1996

All Models

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

Via the vehicle look-up process, the test analyzer automatically ignores monitor status; the monitors are not used for pass/fail decisions.

Toyota

1997

Tercel, Paseo

The evaporative monitor will never set to “complete.”

The Smog Check OBD readiness criteria for these vehicles allow two monitors to be incomplete.

Volkswagen and Audi

1997- 2002

All models with non-OEM stereos

If the OEM stereo has been replaced with an aftermarket stereo, these vehicles may not communicate with OBD code scanners and may cause severe damage to code scanning tools. 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 over current 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.
