WARNING: This page is about a different car, the 2006 Mercury Montego, 2006 Ford Freestyle, and 2006 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.
The SJB sends a message to the instrument cluster over the communication network when the multifunction switch is in the RH and LH turn position. When the multifunction switch is in the RH or LH turn position, the instrument cluster flashes the RH or LH turn indicators.
