B18E0 Description

The Power Liftgate Module monitors the Power Liftgate Handle Switch Circuit. When the handle switch is inactive, the voltage from the module to the switch will be 5.0 volts. When the switch is pressed, the voltage will be approximately 2.2 volts. This can be verified by using the scan tool and monitoring the Handle Switch states or voltage and pressing and releasing the liftgate handle. When the Power Liftgate Module senses the Liftgate Handle Switch Sense circuit active (2.0 V to 3.0 V) for longer than 15 seconds, this code will set.
