Basic Inspection Procedure
Measuring Condition of Electronic Parts' Resistance
The measured resistance at high temperature after vehicle running may be high
or low. So all resistance must
be measured at ambient temperature (20ºC, 68ºF), unless stated otherwise.
Connector Inspection Procedure
Handling of Connector
a. Never pull on the wiring harness when disconnecting connectors.

Low Voltage DC/DC Converter
Specification
Description
The Low Voltage DC/DC is integrated into the HPCU. It charges the auxiliary
battery as a substitute
for generator by converting the high voltage (DC 270V) from the high voltage
battery into low voltage
(DC 12V).
