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.
Description & Operation
The Driver's Position Memory Systems (DPMS) can memorize driver's seat position, power mirror positions and steering column position for 2 different driver's by pressing the MEMO button on the DPMS switch after adjustments have been made. The DPMS switch is located in the driver's door panel. Manual adjustments can also be made.
Memory mirrors use hall-effect type tilt sensor to transmit voltage changes in voltage caused by mirror movement. These voltages are stored in DPMS control unit memory, relative to memorized seat positions.
On driver's seat, 4 motors provide for front up/down, rear up/down, forward/back, and recline adjustment. See Figure. Additionally, 2 motors are used to adjust steering column position. See Figure. Each motor includes a reed-switch sensor, which sends a pulse signal to DPMS control unit.
