Borrego 4WD V6-3.8L (2009)
Turn Signal and Side Repeater Lamps
FAM
Description
The turn signal lamps status is determined by:
-
The left and right turn signal switches
-
The hazard switch
-
The crash unlock activation
-
The RKE lock, unlock, tailgate unlock and panic signals
-
The alarm activation
A sound relay connected to the Cluster manages the "tick" sound during the turn signal lamps activation.
The cluster has two backlight indicators: one for the left Turn Signal lamps and one for the right Turn Signal lamps.
The IPM manages the control logic of the function, and sends the command to the FAM and the RAM that drives the turn signal lamps. The same CAN
signal is used for the front and the rear turn signal activation.
