Circuit Description
WARNING: This page is about a different car, the 2007 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.
The memory seat module (MSM) receives voltage inputs from the tilt/telescope switch based on the position of the switch. The MSM then supplies battery voltage and a ground to the tilt or telescope motor control circuits depending on which direction of movement is requested.
The memory seat module (MSM) determines the position of the steering column based on inputs received from the telescope position sensor, built into the telescoping actuator. The MSM supplies a 5-volt reference and a low reference to the sensor and monitors the column position via the steering column telescope sensor signal circuit.
