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.

Power cable malfunction

Excessive overcurrent occurs 
during precharge (time from 
when SMRP turns on until when 
SMRG turns on).

• Wire harness or connector
• Air conditioning harness assembly
• Compressor with motor assembly
• Inverter with converter assembly
• HV relay assembly
• Floor  wire
• Hybrid vehicle converter (DC/DC 

converter)

• Hybrid vehicle control ECU

801

Minimal overcurrent occurs dur-
ing precharge (time from when 
SMRP turns on until when 
SMRG turns on).

CHECK DTC OUTPUT (HYBRID SYSTEM)

1. Turn ignition switch ON.

2. Check DTC.

Is DTC detected?

YES

>> Go to Diagnosis Procedure relevant to output DTC.

NO

>> GO TO 3.

3.

CHECK CONNECTOR CONNECTION CONDITION (HYBRID VEHICLE CONTROL ECU CONNECTOR)

See 

HBC-109, "Diagnosis Procedure"

.

OK or NG

OK

>> GO TO 4.

NG

>> Connect securely.

4.

CHECK ELECTRIC COMPRESSOR

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 ser-

vice manual because this may cause a malfunction.

2. Disconnect the air conditioning harness from the inverter with

converter assembly (See 

HBC-638, "Removal and Installation"

).

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

below.

NOTE:

• Do not use a megohmmeter.

• Make sure that the tester probes are connected to the correct

terminals.

OK or NG

DTC No.
