Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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.
