How to Troubleshoot EPS DTCs

Special Tools Required

  • DLC terminal box, 07WAJ-0010100
  • SCS short connector, 07PAZ-0010100

The troubleshooting flowchart procedures assume that the cause of the problem is still present and the EPS indicator is still on. Following the flowchart when the EPS indicator does not come on can result in incorrect diagnosis.

The connector illustrations show the female terminal connectors with a single outline and the male terminal connectors with a double outline.

  1. Question the customer about the conditions when the problem occurred, and try to reproduce the same conditions for troubleshooting. Find out when the EPS indicator came on, such as while turning, after turning, when the vehicle was at a certain speed, etc.
  2. When the EPS indicator does not come on during the test drive, but troubleshooting is done based on the DTC, check for loose connectors, poor terminal contact, etc., before you start troubleshooting.
  3. After troubleshooting, clear the DTC and test-drive the vehicle. Be sure the EPS indicator does not come on.
