Test Conditions Normal condition: The motor should not provide steering assist.
Symptom Possible Cause Repair
Ignition OFF The motor provides steering assist. ASP is not calibrated. Perform ASP calibration using the scan tool.
IG Power Supply Circuits Inspect the IG power supply line.

Test Conditions Normal condition: The motor should not provide steering assist, and the warning lamp should illuminate.
Symptom Possible Cause Repair
IG ON / Engine OFF The motor provides steering assist. ASP is not calibrated. Perform ASP calibration using the scan tool.
EMS CAN signal not received. Inspect the CAN line.
The warning lamp does not illuminate. Cluster Malfunction Inspect the cluster and cluster harness.

Test Conditions Normal condition: The motor provides steering assist, and the warning lamp does not illuminate.
Symptom Possible Cause Repair

ASP: Absolute Steering Position, CAN: Controller Area Network, EMS: Engine Management System
The following symptoms may occur during normal vehicle operation. If the EPS warning lamp is not illuminated, it is not a malfunction of the EPS system.
  • After the ignition is turned on, the steering wheel becomes heavier while the EPS system performs diagnostics, for approximately 2 seconds. After that, this becomes normal steering operation.
  • A relay noise from the EPS may be heard after the ignition is turned on or off. This is normal.
  • A motor noise may be heard when steering while the vehicle is stationary or moving at low speed. This is a normal operating noise.
Use caution when performing ASP (Absolute Steering Position) calibration or EPS type recognition.
  • Before calibrating ASP or recognizing EPS type, check that the battery is fully charged.
  • Be careful not to disconnect any cables connected to the vehicle or the scan tool during ASP calibration or EPS type recognition.
  • After ASP calibration or EPS type recognition is complete, turn the ignition switch OFF and wait a few seconds, then start the engine to make sure the vehicle operates normally.
ASP Calibration
  1. Select "Steering Wheel Angle Sensor".
  2. Continue the test in accordance with the instructions on the screen.
  3. Select "EPS Variant Coding".
  4. Continue the test in accordance with the instructions on the screen.
