First, a disclaimer. I know nothing about the CR-V Hondas.
But I do know that cruise control systems must disengage when the brakes are applied, and I’m going to go out on a limb and say that must be triggered by a switch by the brake pedal, perhaps the same one that enables the brake light circuit. You might want to look there. NOTE: do not assume that becaue the brake lights work properly the contacts for the cruise control system aren’t flakey.
