Checking for DTCs
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.
The temperature display indicates single or multiple DTCs. If indicator segments A, C, D, E, G, J, AUTO and A/C are on at the same time, there may be an open in the common ground wire. If no DTCs are present, the indicator remains blank.
