Diagnosis Procedure

INFOID:0000000004219047

1.

CHECK DTC

Check whether or not the DTC related to HEV SYSTEM CAN indicated on All DTC Reading by CONSULT-III.

NOTE:

For DTCs related to HEV SYSTEM CAN, refer to 

LAN-59, "DTC Related to HEV SYSTEM CAN List"

.

Is the DTC related to HEV SYSTEM CAN displayed?

YES

>> Inspect HEV SYSTEM CAN. Refer to 

LAN-53, "Trouble Diagnosis Flow Chart"

.

NO

>> GO TO 2.

2.

CHECK CONNECTOR

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Check the terminals and connectors of the hybrid vehicle control ECU for damage, bend and loose con-

nection (unit side and connector side).

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair the terminal and connector.

3.

CHECK HARNESS FOR OPEN CIRCUIT

1. Disconnect the connector of hybrid vehicle control ECU.

2. Check the resistance between the hybrid vehicle control ECU harness connector terminals.

Is the measurement value within the specification?

YES

>> GO TO 4.

NO

>> Repair the hybrid vehicle control ECU branch line.

4.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the hybrid vehicle control ECU. 

HBC-600, "Wiring Diagram"
