General Troubleshooting Information: Self-diagnosis
WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.
Self-diagnosis can be classified into three categories:
- Initial diagnosis: Done right after the engine starts and until the EPS indicator goes off.
- Regular diagnosis: Done right after the initial diagnosis until the ignition switch is turned to LOCK (0).
- Steering diagnosis: Done during regular diagnosis while turning the steering wheel.
The EPS control unit does the following functions when a problem is detected by self-diagnosis:
- Turns on the EPS indicator.
- Stores the DTC.
- Stops or restricts power assist and manual steering operation resumes.NOTE: For DTCs 11-01,11-02,12-01,21-01,21-02, 22-01,35-04,36-02,37-01, and 37-02 the EPS indicator will go off automatically, and the system returns to normal.
