Description

INFOID:0000000004211852

The hybrid vehicle control ECU monitors its internal operation and detects malfunctions.

DTC Logic

INFOID:0000000004211853

DTC DETECTION LOGIC

The hybrid vehicle control ECU performs diagnostic monitoring to verify proper operation of internal and exter-

nal ECU systems. In one of these diagnostics, the hybrid vehicle control ECU monitors the important RAM

range of the hybrid vehicle control ECU. If the hybrid vehicle control ECU detects an error in the important

RAM circuits, it will conclude that there is an internal malfunction in the hybrid vehicle control ECU. The hybrid

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

Diagnosis Procedure

INFOID:0000000004211854

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.

Description

INFOID:0000000004211855

The hybrid vehicle control ECU monitors its internal operation and detects malfunctions.

DTC Logic

INFOID:0000000004211856

DTC DETECTION LOGIC

When the hybrid vehicle control ECU detects that the HV battery has received too much charge, the hybrid

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

Diagnosis Procedure

INFOID:0000000004211857

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.

>> GO TO 2.

2.

CHECK DTC OUTPUT (HYBRID SYSTEM)

1. Turn ignition switch ON.

2. Check DTC.
Are DTCs other than P0A1D-390 and P3004-133 detected?

YES

>> Go to Diagnosis Procedure relevant to output DTC.

NO

>> Replace hybrid vehicle control ECU (See 

HBC-644, "Removal and Installation"

).

DTC No.

The hybrid vehicle control ECU monitors its internal operation and detects malfunctions.

DTC Logic

INFOID:0000000004211859

DTC DETECTION LOGIC

The hybrid vehicle control ECU performs many diagnostic tests to verify proper operation of internal ECU sys-

tems. In one of these diagnostics, the hybrid vehicle control ECU performs a self-test. If the hybrid vehicle con-

trol ECU detects an internal problem during this self-test, it will conclude that there is an internal malfunction.

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