B1143 - Mode Down Switch 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 mode down 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 mode down switch is stuck in a pushed position. When active, this DTC will prevent proper mode down switch and status indicator function.

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