DTC Troubleshooting Index
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.
NOTE:
Record all DTCs, and sort them by DTC type using the following DTC troubleshooting indexes, then troubleshoot the DTC(s) in this order:
- Battery voltage DTCs
- Internal error DTCs
- Loss of communication DTCs (beginning with the lowest number first; for example, if B1011 and B1155 are retrieved, troubleshoot B1011 first).
- Signal error DTCs
