B1003 - Panel Mode Switch Request Input Circuit/Performance: Notes

For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS information.

Theory of Operation 

The switch input changes when the switch is pushed down. A stored DTC indicates that the panel mode 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 panel mode switch is stuck in a pushed position. An active DTC will prevent proper A/C mode switch and status indicator function.

• >>When Monitored:<< With the ignition on.
• >>Set Condition:<< If the panel mode switch is detected in a pushed position for more than 10 minutes.
