DTC Troubleshooting
| Step | Action | Yes | No |
|---|---|---|---|
| 1 |
Was “Engine and Emission Control System Check” performed?
|
Go to Step 2.
|
|
| 2 |
OCV power supply circuit check
1)With ignition “OFF”, disconnect connector from OCV.
2)Check for proper terminal connection to OCV connector.
3)If connection is OK, set ignition “ON”.
4)Check that voltage between “A1” and ground is battery voltage.
Is check result OK?
|
Go to Step 3.
|
Repair or replace defective wire harness.

OCV drive circuit check
1)With ignition “OFF”, disconnect “C01” and “E01” connectors from ECM.
2)Check for proper terminal connections to “C01” and “E01” connectors.
3)If connections are OK, check the following points.
•Resistance of “A2” circuit: less than 1 Ω
•Resistance between “A2” circuit and ground: infinity •Resistance between “A1” circuit terminal and “A2” circuit terminal at OCV connector: infinity •Voltage of “A2” circuit: approx. 0 V (When ignition is “ON”) Is check result OK?
|
Go to Step 4.
|
Repair or replace defective wire harness.

OCV check
1)Check OCV.
Is check result OK?
|
Go to Step 5.
|
Replace OCV.
