Power Locks

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The SJB  monitors the door lock control switches. When the SJB  receives an unlock/lock command from either door lock control switch, the SJB  energizes a relay (internal to the SJB  ) to supply the correct power and grounds for the door lock actuators.
