How to Enter the Self-Diagnostic Function

WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Always check for and repair any B-CAN or F-CAN DTCs before troubleshooting the AcuraLink system.
  1. Turn the ignition switch to ON (II).
  2. Press and hold the MAP/GUIDE, CANCEL, and MENU buttons at the same time for 3 seconds more, and the self-diagnosis begins.
