Memory Inhibit/Enable

WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.

The memory seat module (MSM) receives the ignition switch signal and the gear selector position via class 2 messages. When the ignition switch is in the OFF position, memory record, memory recall, personalization recall and exit recall functions are all allowed. When the ignition switch is in the ON position and the gear selector is in PARK, the personalization recall function is deactivated, while all other memory functions are allowed. When the ignition switch is in the ON position and the gear selector is out of the PARK position, all memory seat recall functions are inhibited, only memory set is allowed.

After an air bag deployment, the sensing and diagnostic module (SDM) will send out a post air bag deployment signal via the class 2 serial data line. After receiving this message, the MSM will inhibit all memory recall functions or cancel any memory recall function in process.
