Checking for DTCs
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2014 Honda Ridgeline, 2013 Honda Ridgeline, 2012 Honda Ridgeline, 2011 Honda Ridgeline, and 2010 Honda Ridgeline. 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, E, G, J, and M 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.
