.

OK or NG

OK

>> GO TO 5.

NG

>> Connect securely. 

5.

CHECK HARNESS AND CONNECTOR (RESISTANCE VALUE OF NODD INSIDE HYBRID VEHICLE

CONTROL ECU)

1. Disconnect the HV battery harness connector B130 (See 

HBB-97, "Removal and Installation"

).

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

below.

OK or NG

OK

>> GO TO 6.

NG

>> GO TO 12.

6.

CHECK CONNECTOR CONNECTION CONDITION (HV RELAY ASSEMBLY CONNECTOR)

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 Sys-

tem"

).

NOTE:

After removing the service plug grip, do not Turn ignition switch

to READY position, unless instructed by the repair manual

because this may cause a malfunction.

2. Check the connections of the HV relay assembly connectors.

NOTE:

For the removal procedure of the HV relay assembly connector,

(See 

HBB-105, "Removal and Installation"

).

The connectors are connected securely and there are no contact

problems.

OK

>> GO TO 7.

NG

>> Connect securely.

7.

CHECK HV RELAY ASSEMBLY (HIGH VOLTAGE FUSE)

DTC No.

CAUTION:

Be sure to wear insulated gloves.

1. Check that the service plug grip is not installed.

2. Remove the HV relay assembly (See 

HBB-105, "Removal and Installation"

).

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

below.

OK or NG

OK

>> GO TO 8.

NG

>> Replace high voltage fuse.

8.

CHECK CONNECTOR CONNECTION CONDITION (HYBRID VEHICLE CONVERTER CONNECTOR)

See 

HBC-140, "Diagnosis Procedure"

.

OK or NG

OK

>> GO TO 9.

NG

>> Connect securely.

9.

CHECK HARNESS AND CONNECTOR (HV BATTERY CONNECTOR - HYBRID VEHICLE CONVERTER)

CAUTION:

Be sure to wear insulated gloves.

1. Check that the service plug grip is not installed.

2. Disconnect the hybrid vehicle converter connector (DC/DC converter) (See 

HBB-103, "Removal and

Installation"

).

3. Turn ignition switch ON.

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

NOTE:

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

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

5. Turn ignition switch OFF.

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

CHECK HYBRID VEHICLE CONVERTER

1. Connect all the disconnected connectors.

2. Install the service plug grip.

3. Measure the current output from the hybrid vehicle converter

(DC/DC converter) with the headlight position switch and blower

motor switch in the HI position, and the rear window defogger

turned on (*1).

4. Measure the auxiliary battery voltage according to the previous

conditions (*1).

OK or NG

OK

>> GO TO 11.

NG

>>  Replace hybrid vehicle converter (See 

HBC-644, "Removal and Installation"

).

11.

CHECK FOR INTERMITTENT INCIDENT

1. Check for intermittent incident (See 

GI-42, "Intermittent Incident"

).

YES or NO

YES

>> Repair or replace malfunctioning parts, component and area.

NO

>> Replace hybrid vehicle converter (See
