Amplifier Interface (GMLAN)
WARNING: This page is about a different car, the 2008 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.
A 30A AMPLIFIER fuse, located in the rear BEC, provides the main amplifier power for the amplifier. The amplifier does not require a remote enable circuit for power moding. The power moding is accomplished using a structure of Virtual Networks (VN).
The amplifier supports the following signals:
- System Power Mode
- Infotainment Operation Allowed
The amplifier also supports the following GMLAN Vehicle Power Modes:
- OFF
- ACCESSORY
- RUN
- CRANK REQUEST
The radio controls the overall muting of the amplifier and commands the amplifier to perform the following via serial data (GMLAN) messaging:
- Volume
- Balance
- Fade
- Bass
- Midrange
- Treble
- DSP Modes
- Volume Compensation
- Chime Output
