Unlatch Output
WARNING: This page is about a different car, the 2006 Dodge Viper. However, it is still accessible from the selected car via links, so may be relevant.
When the BCM is required to perform an unlatch function, the output power wave to drive the doors off of the primary latch is:
- Power ON for 63ms.
- Power OFF for 31ms.
- Power ON for 94ms.
A single pulse to the unlatch motors causes breakage of the gears. A dual pulse lessens the motor torque and provides longer life to the gears.
