Signal Specification
General
All the values given below are between the respective terminal in column 1 and terminal #C1-6 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 the appropriate 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 % |

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.
