CMBS Indicator

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 system is normal, the CMBS indicator comes on for about 2 seconds after turning the ignition switch to ON (II).

The CMBS indicator comes on when the adaptive cruise control (ACC) unit detects a problem in the system.

NOTE:

The ACC indicator indicates problems related with the ACC system and the CMBS.
The CMBS indicator only indicates its system problems.
The CMBS works with related systems such as the VSA system. If these related systems have a problem, the CMBS does not operate. In this case, the CMBS indicator and the related system indicator come on.

When a problem is detected by the self-diagnostic function, the CMBS stops operating, turns on the CMBS indicator, indicates the problem on the MID, and stores the DTC.
