Radio Power: Notes

The main radio power is supplied by a 15A fuse located in the under hood 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:

• Infotainment Operation Allowed

The radio also supports the following GMLAN Vehicle Power Modes:

• ACCESSORY
