Load Management

WARNING: This page is about a different car, the 2002 Oldsmobile Aurora and 2001 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.

There are 3 levels of load management controlled by the dash integration module (DIM). The DIM sends the status of load management to the rear integration module (RIM) via a class 2 message. In response to this message, the RIM then signals the heated seat modules through the heated seat control module inhibit signal circuit indicating the current load management level. During load shed level 0, the RIM does not inhibit the operation of the heated seats.

During load shed level 1, the heated seats that are on are cycled 10 seconds on and 10 seconds off, with temperature regulation still being enforced. During load shed level 2, the RIM will pull the heated seat control module inhibit signal circuit of the heated seat module to ground. In response to this signal, the heated seat modules will turn off the heated seats and deactivate temperature indicators. The instrument cluster will display a BATTERY SAVER ACTIVE message. The ON/OFF status of the heated seats is reported to the RIM through the heated seat control module status signal circuit by both heated seat modules.
