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.
Personalization Option
The memory seat module (MSM) cannot perform memory recall functions unless the Personalization Option is enabled. The personalization is located in the radio (IRC). The radio reports the personalization setting to the MSM, as well as other receiving modules, via GMLAN message each time the ignition is cycled to the ON position. The MSM will then store the personalization option setting and examine it before making a memory seat adjustment. The personalization option setting stored within the MSM will not change until the personalization setting in the radio is changed.
