P2592 marks a fault of the right-hand front distance sensor in multi-radar adaptive cruise layouts; the left unit reports P2591, a single or centre radar P2583. No maker publishes this code. Compared with a radar behind the grille emblem, a right corner sensor is more exposed to kerb and parking contact, stone chips and road salt reaching its connector, and it is often disturbed when a bumper is replaced on the passenger side. That is why aiming and mounting are checked before parts are swapped. Honda's P2583 bulletins illustrate the usual chain: dirt or ice on the radar face leads to a misalignment report and a temporary shutdown of the assistance. The engine module only keeps the record; the detailed cause is stored in the driver assistance or radar module. Driving itself is unaffected.
