HINT: If the "Inverter Low-voltage Circuit" inspection results are normal, perform the next step. REPLACE INVERTER WITH CONVERTER ASSEMBLY DESCRIPTION The DC/DC
converter varies output voltage based on voltage change signals (VLO
signal line) received from the motor generator control ECU. If
the vehicle is being driven with an inoperative DC/DC converter, the
voltage of the auxiliary battery will drop, which will prevent the
continued operation of the vehicle. Therefore, the motor generator
control ECU monitors the operation of the DC/DC converter and alerts the
driver if it detects a malfunction.
