OCCUPANT CLASSIFICATION SYSTEM TERMINALS OF ECU


  1. OCCUPANT DETECTION ECU

    A01G9WHE09

    Tech Tips

    Since the occupant detection ECU uses waterproof connectors, the voltage and waveform cannot be inspected directly. Standard voltage and resistance readings and waveforms are indicated for reference only.
