Smog Check Inspection Manual
TABLE 1 – OBD II Testability Issues
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.
Readiness monitors are difficult to complete. Must successfully complete drive cycle TWO times.
Hyundai TSB #02-36-030 applies. Hyundai TSB information at: <http://hmaservice.com/webtech>
Will not communicate with generic OBD-II test equipment.
A manufacturer recall is in effect; recall campaign #057 and Hyundai TSB #03-01-003-01. Refer to dealership for recall.
The catalyst and evaporative monitors are difficult to set to “complete.”
Nissan provides recommended drive cycles (drive patterns). See Nissan Technical Service Bulletin #NTB98- 018, February 18, 1998.
C220, E320, C280, S320, SL320
The MIL illuminates whenever a scan tool is connected to the DLC. Trouble codes are not stored. However, if the OBDII connector is used as an rpm source during the Smog Check, the MIL will illuminate.
Do not connect the OBDII connector until the analyzer prompts for the OBDII functional test. Use the conventional contact or non-contact method to obtain an rpm signal.
No communication with some Snap-On BAR-97s.
Snap-On produces a revised chip that enables communication. If your Snap-On BAR-97 does not use the revised chip, do not inspect these vehicles; they will NOT communicate. Refer the motorist to another station for inspection.
Diamante, 3000GT, 3000GT Spyder, Montero, and Montero Sport, all equipped with 3.0L or 3.5L V6 engines.
All monitors reset to “incomplete” upon ignition key-off if all monitors set to “complete” prior to ignition off.
The test analyzer ignores monitor status. The Smog Check OBD readiness criteria for these vehicles allow all monitors to be incomplete.
All models (Montero most commonly affected)
A defect in these systems causes the MIL to be commanded on without setting any DTCs. ARB believes that only a small population of Mitsubishi vehicles produced early for the 1996 model-year is affected by this problem.
Manufacturer recall in effect; refer to dealer for Mitsubishi recall #EMR-02- 01.
