Memory Seat System
An electronic memory seat system is available on certain models. The memory seat system is able to store and recall all driver side power seat positions, driver side power rear view mirror position and power steering column position, when equipped. The system can be set for two different drivers. The memory system is also able to store and recall up to twenty radio station presets for two drivers (ten AM and ten FM). The memory system also will store and recall the last station listened to for each driver, even if it is not one of the twenty preset stations.
The memory system will automatically recall all of these settings when a button of the memory switch (2) located on the driver door trim panel (1) is pressed, or when the doors are unlocked using a FOBIK transmitter (if enabled).
The memory system also has a customer programmable easy exit feature. When the ignition switch is turned off, the driver seat will move rearward 55 millimeters (2.2 inches) or to the end of its travel, whichever occurs first.
The memory system includes the following components:
- Body Control Module (BCM) - located behind the passenger side of the instrument panel.
- FOBIK Transmitter - located in each key fob.
- Hall Effect Sensors - Power Drivers Mirror - located in the two drivers side view mirror motors. Used to provide a reference signal to the memory seat module, letting the module know the exact position of the mirror.
- Hall Effect Sensors - Power Seat - located in each of the power seat track and recliner motor. Used to provide a reference signal to the memory seat module, letting the module know the exact position of the seat and recliner.
- Hall Effect Sensors - Power Adjustable Steering Column - located in the two steering column motors. They are used to provide a reference signal to the memory seat module, letting the module know the exact position of the column.
- Memory Seat Module (MSM) - located underneath the driver seat.
- Memory Seat Switch - located in the driver door trim panel.
- Keyless Ignition Node (KIN) - located in the instrument panel.
Certain functions and features of the memory system rely upon resources shared with other electronic modules in the vehicle over the Controller Area Network (CAN) data bus. The CAN bus allows the sharing of sensor information. This helps to reduce wire harness complexity, internal controller hardware and component sensor current loads. At the same time, this system provides increased reliability, enhanced diagnostics and allows the addition of many new feature capabilities. A scan tool is required for diagnosis of the electronic modules and the CAN bus (Refer to BODY CONTROL MODULE (BCM) - DIAGNOSTIC CODE INDEX .
