Hybrid Vehicle Control ECU

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