Signal Description
General
All the values given below are between the respective terminal in column 1 and terminal #C1-7 in column 2 (power ground) unless otherwise stated in parenthesis after the table entry.
NOTE:
It is important to connect the breakout box and check the ground connections before starting to measure.
There may be several connections and connectors between the control module and components. For more information about these, see relevant section in Wiring diagram.
| 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 |
| PWM = | Pulse width modulated signal as a % |
