B1140 - Rear Power Lock Out 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 rear power lock out 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 rear power lock out switch is stuck in a pushed position. When active, this DTC will prevent proper rear power lock out switch and status indicator function.

Possible Causes
OBJECT HOLDING THE REAR POWER LOCK OUT SWITCH IN A PUSHED POSITION
SUBSTANCE CAUSING THE REAR POWER LOCK OUT SWITCH TO GET STUCK IN A PUSHED POSITION
A/C HEATER CONTROL
