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.
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 |

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
