• When the battery is disconnected or discharged Readiness codes that are set during ordinary driving are erased. Also, depending on your driv-ing habits, the readiness codes may not be completely set.
• When the fuel tank cap is loose The malfunction indicator lamp comes on indicating a temporary malfunction and your vehicle may not pass the I/M test.
