Description

INFOID:0000000004211816

The inverter with converter assembly (MG ECU) monitors its internal operation and detects malfunctions.

DTC Logic

INFOID:0000000004211817

DTC DETECTION LOGIC

The MG ECU performs many diagnostic tests to verify proper operation of internal ECU systems. For one of

these diagnostics, the MG ECU checks the result of the generator CPU self-test. If the MG ECU detects a

“Fail” from the generator CPU self-test, it will conclude that there is an internal malfunction in the generator

CPU. The hybrid vehicle control ECU will illuminate the MIL and set a DTC.

Diagnosis Procedure

INFOID:0000000004211818

1.

PRECONDITIONING

• Before inspecting the high-voltage system or disconnecting the low voltage connector of the inverter with

converter assembly, take safety precautions such as wearing insulated gloves and removing the service

plug grip to prevent electrical shocks. After removing the service plug grip, put it in your pocket to prevent

other technicians from accidentally reconnecting it while you are working on the high-voltage system.

• After disconnecting the service plug grip, wait for at least 10 minutes before touching any of the high-voltage

connectors or terminals.

• Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with

converter assembly.ol Module

DTC Logic

INFOID:0000000004211823

DTC DETECTION LOGIC

The MG ECU (in the inverter with converter assembly) performs many diagnostic tests to verify proper opera-

tion of internal ECU systems. For this diagnostic monitor, the MG ECU checks for an R/D (Resolver/ Digital

converter) malfunction involving the motor resolver. If the MG ECU detects an R/D converter error, it will con-

clude that there is an internal malfunction involving the motor resolver. The hybrid vehicle control ECU will illu-

minate the MIL and set a DTC.
