Theory of Operation

- When Monitored:
With the ignition on.

- Set Condition:
If the A/C mode switch is stuck in a pushed position for more than 20 seconds. This DTC has a maturing time of 20 seconds and a de-maturing time of 20 seconds. If the DTCs status changes from active to stored it will stay in memory for 100 ignition cycles.
