Theory Of Operation

WARNING: This page is about a different car, the 2021 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

The Memory System is made up of a Memory Seat Module-Driver (MSMD), Memory Switch, Driver Seat Switch, and multiple Seat Motors. If equipped the Memory System can also contain an Adjustable Pedal Motor, Adjustable Pedal Switch, Steering Tilt/Telescope Switch, Steering Telescope Motor and Steering Tilt Motor. The motors each contain a hall-effect position sensor. The hall-effect position sensor provides feedback to the MSMD in relation to the motors position.

The Tilt/Telescope Steering Switch is a 4-way switch that operates the steering column in an up/down tilt direction and in a forward/rearward telescope direction. The MSMD monitors the steering column tilt/telescope position by reading the Tilt Steering Up/Down Position Sense and Telescope Steering Forward/Rearward Position Sense voltages. If the MSMD detects a change in these voltages it commands the corresponding motor to adjust the steering column accordingly.
