MOTOR GENERATOR CONTROL SYSTEM TERMINALS OF ECU


  1. A001RCRC13
    *1 Inverter with Converter Assembly

    Tech Tips

    Since the inverter with converter assembly uses waterproof connectors, the voltage and waveforms cannot be inspected directly. Standard voltage readings and waveforms are indicated for reference only.
