Signal Specification, Audio Module (AUD)
GENERAL
NOTE:
There are several versions of the audio module (AUD) and the version found in a specific vehicle is dependent on model and equipment level. This list does not describe the different versions, only the different functions of the connectors and signals.
| U= | DC voltage in volts (V) | UAC = | AC voltage in volts (V) |
| Ubat = | Battery voltage (V) | f = | Frequency in Hertz (Hz) |
| Ulow = | Voltage approximately 0 V | t = | Time in seconds (s) |
| PWM = | Pulse width modulated signal in % |
