This applies to all Acura vehicles equipped with CMBS (collision mitigation braking system) where the millimeter wave radar looks through the front grille upper molding.
If the CMBS indicator is on with DTC P2583-97 (dust or dirt on the wave radar possible), before going into heavy troubleshooting, make sure that the vehicle does not have a non-CMBS front grille upper molding. This could happen if the vehicle has had some body work done and a non-CMBS molding was installed.
The millimeter wave radar can’t see through that type of molding. The back surface of the CMBS front grille upper molding is dull black. The molding for the non-CMBS is metallic-looking. Replace the molding if necessary.
