Description

INFOID:0000000004212044

Refer to the description for DTC P0AE6-225 (See 

HBC-460, "Description"

). This circuit uses the hybrid vehicle

control ECU to monitor the system main relays and stops the system if a malfunction is detected in the relays,

because it may be impossible to shut off the high-voltage system if any of the relays becomes stuck.

DTC DETECTION LOGIC

This circuit uses the hybrid vehicle control ECU to monitor the system main relays and stops the system if a

malfunction is detected in the relays, because it may be impossible to shut off the high-voltage system if any of

the relays becomes stuck.

Diagnosis Procedure

INFOID:0000000004212046

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.

• If P0AA1-233 is output, the vehicle is prevented from starting.

>> GO TO 2.

CHECK DTC OUTPUT (HYBRID SYSTEM)

1. Turn ignition switch ON.

2. Check DTC.

< COMPONENT DIAGNOSIS >

Is DTC detected?

YES

>> Go to  Diagnosis Procedure relevant to output DTC.

NO

>> GO TO 3.

3.

CHECK HV RELAY ASSEMBLY (SMRB, SMRG)

CAUTION:

Be sure to wear insulated gloves.

1. Turn ignition switch OFF and remove the service plug grip (See 

HBC-632, "Precautions for Inspecting the

Hybrid Control System"

).

NOTE:

After removing the service plug grip, do not turn ignition switch ON (READY), unless instructed by

the service manual because this may cause a malfunction.

2. Disconnect the high voltage connector of the HV relay assembly (See 

HBB-105, "Removal and Installa-

tion"

).

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

below. (SMRB inspection) (*1)

NOTE:

•  Leave the HV relay in the vehicle while testing to prevent

the movement that occurs during removal from causing a

stuck relay to return to normal.

• Measuring resistance can determine that this is either a present or past malfunction.

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

below. (SMRG inspection) (*2)

NOTE:

• Leave the HV relay in the vehicle while testing to prevent

the movement that occurs during removal from causing a

stuck relay to return to normal.

• Measuring resistance can determine that this is either a present or past malfunction.

Description

INFOID:0000000004212047

The SMRs (System Main Relay) are the relays that connect or disconnect the high voltage power system in

accordance with commands from the hybrid vehicle control ECU.

The SMR system is composed of three SMRs and one system main resistor. SMRB and SMRG are located on

the HV relay assembly in the battery carrier under the HV battery. SMRP and the system main resistor are

located in the hybrid vehicle converter (DC/DC converter) assembly in the battery carrier.

To connect to the high voltage power system, the vehicle will first turn on SMRP and SMRB to charge the vehi-

cle through the system main resistor. Then, SMRP will be turned off after the SMRG is turned on. To shut off

the high voltage power system, SMRB and SMRG are turned off.

When there is an open in the AMD line or IGCT line, the following DTCs are output:

P0AE6-225 is output first because the time required for diagnosis is the shortest.
