Diagnosis Procedure
- CHECK THE TEMPERATURE OF CONTROL MODULE
CONSULT
- Start the engine.CAUTION: Never drive the vehicle.
- On the CONSULT screen, select "EPS/DAST 3">>"DATA MONITOR">>"C/M TEMPERATURE".
- 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.
- Start the engine.
- PERFORM SELF-DIAGNOSIS
CONSULT
- Ignition switch ON.
- Erase "Self Diagnostic Result" mode of "EPS/DAST 3".
- Ignition switch OFF and wait for at least 10 seconds.
- Start the engine.CAUTION: Never drive the vehicle.
- Select "Self Diagnostic Result" mode of "EPS/DAST 3".
Is DTC "C13E6-00" detected?
YES
Replace steering force control module. Refer to Removal and Installation .
NO
The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. Inspection End
- CHECK TEMPERATURE SENSOR POWER SUPPLY (1)
- Ignition switch OFF.
