DTC Advanced Diagnostics: Notes

NOTE: 

• Initial Diagnosis:

  The initial on-board diagnosis occurs right after the vehicle condition is turned to the ON mode, and the EPS indicator comes on, and continues until the indicator goes off.

• Regular Diagnosis:

  The regular on-board diagnosis begins right after the EPS indicator goes off, and it continues until the vehicle condition is turned to the OFF (LOCK) mode.

• Review "How to troubleshoot the EPS system" before doing the DTC troubleshooting procedure.
• Test-drive the vehicle according to local traffic conditions and regulations. Do not test-drive on a lift unless specified.
• The possible causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
