Theory of Operation
The switch input changes when the switch is pushed down. A stored DTC indicates that the A/C request switch was stuck in a pushed position for more than 10 minutes, but has since returned to its normal state. An active DTC indicates that the A/C request switch is stuck in a pushed position. When active, this DTC will prevent proper A/C request switch and status indicator function.
- >>When Monitored:<< With the ignition on.
- >>Set Condition:<< If the A/C request switch is detected in a pushed position for more than 10 minutes.
