Adaptive Cruise Control (ACC) Indicator (Amber)
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.
When the ACC system is normal, the ACC indicator comes on for about 2 seconds after turning the ignition switch ON (II), then it goes off.
When the ACC system detects a problem while in operation, the ACC system stops control, and the ACC indicator changes from green to amber and stays on.
NOTE:
The ACC system is communicating with the PCM, the VSA system, and the gauge control module by F-CAN. If a connected unit malfunctions, the ACC system will not operate. In this case, both the ACC indicator and the connected unit indicator come on and stay on (except the gauge control module).
