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"

.

Is the inspection result normal?

YES (Present error)>>Replace the hybrid vehicle control ECU. Refer to 

HBC-644, "Exploded View"

.

YES (Past error)>>Error was detected in the hybrid vehicle control ECU branch line.

NO

>> Repair the power supply and the ground circuit.

Diagnosis Procedure

INFOID:0000000004219096

1.

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 IPDM E/R for damage, bend and loose connection (unit side

and connector side).

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS FOR OPEN CIRCUIT

1. Disconnect the connector of IPDM E/R.

2. Check the resistance between the IPDM E/R harness connector terminals.

Is the measurement value within the specification?

YES

>> GO TO 3.

NO

>> Repair the IPDM E/R branch line.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the IPDM E/R. Refer to 

PCS-22, "Diagnosis Procedure"

.

Is the inspection result normal?

YES (Present error)>>Replace the IPDM E/R. Refer to 

PCS-39, "Removal and Installation"

.

YES (Past error)>>Error was detected in the IPDM E/R branch line.

NO

>> Repair the power supply and the ground circuit.
