How To Use the Climate Control Unit Self-diagnostic Function Without the HDS
WARNING: This page is about a different car, the 2011 Honda Pilot, 2010 Honda Pilot, and 2009 Honda Pilot. However, it is still accessible from the selected car via links, so may be relevant.
The climate control unit has a self-diagnostic function. To run the self-diagnostic function, do the following:
- Turn the ignition switch to LOCK (0), and then ON (II).
- Press and hold the FAN ON/OFF button, then press the REAR WINDOW DEFOGGER button five times within 10 seconds. Release the FAN ON/OFF and REAR WINDOW DEFOGGER buttons; then the self-diagnostic begins.NOTE:
- The blower motor should run at various speeds regardless of what the panel is displaying.
- If there is any problem in the system, the system flashes "88 AUTO WINDSHIELD DEFROST" or alternately flashes "88 AUTO WINDSHIELD DEFROST" and one or more of the 14 segments (A through P). Refer to checking for DTCs.
- If there are no problems detected, the segments will not illuminate, and the system will appear to be turned off.
Canceling the Self-diagnostic Function
- Turn the ignition switch to LOCK (0), to cancel the self-diagnostic function. After completing the repair work, run the self-diagnostic function again to make sure that there are no other DTCs.
