NOTE: If the MDPS warning light does not illuminate, the following symptoms are normal:
  • Immediately after starting the engine, there is no temporary auxiliary steering force during the MDPS system self-diagnosis time (about 2 seconds), but this is not a malfunction.
  • Noise due to relay connection on engine On or Off, but this is normal operating sound.
  • Noise due to motor rotation during steering or low-speed driving, but this is normal operating sound.
