Checking for DTCs
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 Honda Crosstour, 2014 Honda Crosstour, 2013 Honda Crosstour, 2012 Honda Crosstour, and 2011 Honda Accord Crosstour. However, it is still accessible from the selected car via links, so may be relevant.
The temperature display indicates single or multiple DTCs. If no DTCs are present, the indicator remains blank.
NOTE:
If indicator segments A, C, D, E, G, J, and the AUTO indicator or the A/C ON indicator are on at the same time, there may be an open in the climate control unit ground circuit.
