4. Connect the battery cable to the negative terminal. Erase the DTCs of unit connected to HEV SYSTEM

CAN and CAN. 

5. Perform All DTC Reading with CONSULT-III. Check if the symptoms listed below are reproduced.

• *1: Hybrid vehicle control ECU may display one or more DTCs (INF code) listed as follows; U0100 (211), U0100 (212), U0100

(530).

• *2: Hybrid vehicle control ECU may display one or more DTCs (INF code) listed as follows; U0129 (220), U0129 (222), U0129

(528).

• *3: Hybrid vehicle control ECU may display one or more DTCs (INF code) listed as follows; U0131 (433), U0131 (434).

Are the symptoms listed above reproduced?

YES

>> Connect the connector. Check other units as per the above procedure.
