DYNAMIC RADAR CRUISE CONTROL SYSTEM TERMINALS OF ECU


  1. CHECK HYBRID VEHICLE CONTROL ECU

    A005NBZE14

    Tech Tips

    The standard voltage, resistance and waveform between each pair of the hybrid vehicle control ECU terminals is shown in the table below. The appropriate conditions for checking each pair of the terminals is also indicated. The result of checks should be compared with the standard voltage, resistance and waveform for each pair of the terminals as displayed in the Specified Condition column. The illustration above can be used as a reference to identify the hybrid vehicle control ECU terminal locations.
