Signal Specification, Infotainment Control Module (ICM)
General
All the values given below apply between the respective terminal (column 1) and power ground (#5). If this is not the case, it is indicated within brackets.
NOTE:
It is important to connect the breakout box and check the ground connections before starting to measure.
| 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 modulation |
