Circuit Inputs

WARNING: This page is about a different car, the 2009 GMC Sierra and 2009 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.

In addition to GMLAN parameters, each MCM monitors its respective motor generator for voltage, current, speed, direction and temperature. Additionally, the MCM monitors the IGBT components for temperature and proper operation. Some of the MCM operation data is shared with the HPCM.
