Set Condition
- If the ESIM does not close before the engine is started for a minimum time of 2 hours a fail event is recorded. If no ESIM Switch closures were recorded for a minimum of 4 straight "fail events" the accumulative timer has reached 70 hours of engine off time and 100 minutes of engine run time, it is determined that a small leak is present.
- All other Evap system faults should be diagnosed before performing the small leak diagnostics.
