Smog Check Manual - Functional Tests
1. OBD I; OBD IIANS
The malfunction indicator light (MIL) or "Check Engine Light" shallbe checked on all vehicles equipped with...
2. KOEOANS
During the MIL functional test, the MIL should illuminate in this keyposition.
3. KOERANS
During the MIL functional test, the MIL should extinguish when the key isin this position.
4. FailANS
If the MIL does not illuminate at all during the MIL functional test, what arethe results of the test?
5. FailANS
If the MIL illuminates continuously during the MIL functional test, what arethe results of the test?
6. FailANS
If the MIL flashes with the engine running during the MIL functional test, whatare the results of the test?
7. Using the vehicle manufacturer's procedure to complete the KOEO/KOER sequencesANS
For vehicles with keyless ignition systems, how should the MIL func-tional test be completed?
8. NoANS
Are maintenance reminder lights part of the Smog Check inspection?
9. 14,000 lbsANS
Most vehicles with a GVWR greater than this are not equipped withan OBD II system.
10. The OBD II functional test is not performed on these vehiclesANS
How shouldan inspector proceed with the OBD II functional test if a vehicle is not equipped withan OBD II system?
11. OBD II functional testANS
This test evaluates and reports the status and/or resultsof the readiness monitors, system faults, and MIL.
12. When prompted by the EIS or OISANS
During an OBD II functional test, whenshould the inspector connect the DLC to the vehicle?
13. Refer to the appropriate electronic component location manual or emis- sion control diagnostic and
repair manualANS
What should the inspector do if theyare unable to find the DLC?
14. Problems communicating with the OBD II systemANS
This condition may con-stitute a failure of the OBD II functional testANS
15. Incompleteness of one or more readiness monitorsANS
This condition mayconstitute a failure of the OBD II functional testANS
16. The presence of DTCsANS
This condition may constitute a failure of the OBD IIfunctional testANS
17. MIL command statusANS
This condition may constitute a failure of the OBD IIfunctional testANS
18. The existence of system modificationsANS
This condition may constitute a failureof the OBD II functional testANS
