3. Disconnect the hybrid vehicle converter (DC/DC converter) con-

nector n4.

4. Turn ignition switch ON.

5. Measure the voltage according to the value(s) in the table below.

NOTE:

Turning ignition switch ON with the hybrid vehicle control ECU connector disconnected causes other

DTCs to be stored. Clear the DTCs after performing this inspection.

Description

INFOID:0000000004211810

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

DTC Logic

INFOID:0000000004211811

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:0000000004211812

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

Description

INFOID:0000000004211813

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

DTC Logic

INFOID:0000000004211814

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 generator resolver. If MG ECU detects an R/D error, it will conclude that

there is an internal malfunction involving the generator resolver. The hybrid vehicle control ECU will illuminate

the MIL and set a DTC.
