Radio Power: Notes
WARNING: This page is about a different car, the 2007 GMC Sierra and 2007 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
The main radio power is supplied by a 15A fuse located in the underhood fuse block. The radio does not require a discrete ignition feed circuit for power moding. The power moding is accomplished using a structure of Virtual Networks (VN). The Power Mode Master (PMM) transmits the GMLAN power mode signals.
The radio supports the following signals:
- System Power Mode
- Infotainment Operation Allowed
The radio also supports the following GMLAN Vehicle Power Modes:
- OFF
- ACCESSORY
