Body Control Systems: Description and Operation

MODULE CONTROLLED FUNCTIONS

There are 3 multifunction electronic control modules on this vehicle. The smart junction box (SJB), drivers door module and driver seat module.

The SJB is a combination of a multifunction control module and an interior power junction box. SJB functions control multiple systems, which include:
- illuminated entry and interior lamps
- exterior lamps
- horn
- remote keyless entry (RKE) system
- power door locks
- smart locks
- windshield wiper

The driver door module (DDM), if equipped, is located under the LH front door panel. It works in conjunction with the driver seat module (DSM) located under the driver seat, to control the memory functions of the exterior driver memory mirror and the memory seat positions.

The DSM controls the exterior passenger memory mirror and the power adjustable seat motors functions.
