>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS FOR OPEN CIRCUIT

1.

Disconnect the connector of EPS control unit.

2.

Check the resistance between the EPS control unit harness connector terminals.

Is the measurement value within the specification?

YES

>> GO TO 3.

NO

>> Repair the EPS control unit branch line.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the EPS control unit. Refer to 

STC-40, "Diagnosis Proce-

dure"

.

Is the inspection result normal?

YES (Present error)>>Replace the EPS control unit. Refer to 

STC-50, "Removal and Installation"

.

YES (Past error)>>Error was detected in the EPS control unit branch line.
NO

>> Repair the power supply and the ground circuit.
