Description

INFOID:0000000004211769

Battery power is constantly supplied to the BATT terminal of the hybrid vehicle control ECU to allow DTCs and

freeze frame data to be retained in memory even though the ignition switch is turned OFF. The back-up power

is supplied even when the ignition switch is OFF.

DTC Logic

INFOID:0000000004211770

DTC DETECTION LOGIC

If a period of time has elapsed with a low voltage at the BATT terminal of the hybrid vehicle control ECU, the

hybrid vehicle control ECU will determine that a malfunction has occurred in the back-up power supply sys-

tem, and set a DTC. The MIL will illuminate the next time the engine is started.

Diagnosis Procedure

INFOID:0000000004211771

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.

2.

CHECK CONNECTOR CONNECTION CONDITION (HYBRID VEHICLE CONTROL ECU CONNECTOR)

Refer to 

HBC-109, "Diagnosis Procedure"

.

OK or NG

OK

>> GO TO 3.

NG

>> Connect securely.

3.

CHECK HARNESS AND CONNECTOR (HYBRID VEHICLE CONTROL ECU - FUSE)

1. Turn ignition switch OFF.

2. Remove the 10A fuse (No. 70) from the high voltage fuse and fusible link box.

3. Disconnect the hybrid vehicle control ECU harness connector E65.

4. Measure the resistance according to the value(s) in the table below.

Check for open

CHECK HARNESS AND CONNECTOR (FUSE - BATTERY POSITIVE TERMINAL)

1. Disconnect the positive and negative terminals from the auxiliary battery.

2. Measure the resistance according to the value(s) in the table below.

RECONFIRM DTC OUTPUT (HYBRID SYSTEM)

NOTE:

If DTC P0560-117 is output after this inspection, replace the hybrid vehicle control ECU. If the DTC is not out-

put, check for intermittent incident because there may be a malfunction in the wire harness or connector.

• Connect the CONSULT-III to the data link connector.

• Turn ignition switch ON.

• Select “DELF-DIAG RESULTS” mode.

• Recheck for DTCs.
DTC P0560-117 is output again.

YES

>> Replace hybrid vehicle control ECU (See 

HBC-644, "Removal and Installation"

).

NO

>> Check for intermittent incident (See 

GI-42, "Intermittent Incident"

).
