DTC Diagnosis Procedure

With CONSULT

1. Start the engine.
   CAUTION: Never drive the vehicle.
2. On the CONSULT screen, select "EPS/DAST 3">>"DATA MONITOR">>"C/M TEMPERATURE".
3. Wait with the ignition switch OFF until the data monitor indication becomes 140 deg. C (284 deg. F) or less.

Does the temperature drop to 140 deg. C (284 deg. F) or less?

YES

GO TO 2.

NO

GO TO 3.

With CONSULT

1. Turn the ignition switch ON.
2. Erase self-diagnosis for "EPS/DAST 3".
3. Turn the ignition switch OFF and wait for at least 10 seconds.
4. Start the engine.
   CAUTION: Never drive the vehicle.
5. Perform self-diagnosis for "EPS/DAST 3".

Is DTC "C13E6-00" detected?

YES

Replace steering force control module. Refer to STEERING FORCE CONTROL MODULE : Removal & Installation .

NO

The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. INSPECTION END

1. Turn the ignition switch OFF.
2. Disconnect force motor angle sensor harness connector.
3. Turn the ignition switch ON.
4. Check the voltage between force motor angle sensor harness connector terminals.

   Force motor angle sensor			Voltage
