On-Board Diagnostics: Operation: Operation: Notes
The following procedure has been established to assist technicians in the field with enabling and running OBD II monitors. The order listed in the following procedure is intended to allow the technician to effectively complete each monitor and to set the California Air Resources Board (CARB) Readiness Status in the least time possible.
NOTE:
Once the monitor run process has started, do not turn off the ignition. By turning the ignition key off, monitor enabling conditions will be lost. The EVAP monitor runs after key off.
