This door switch assembly is used on many modern Honda models from approximately 2012 through 2022 and later, including Civic (10th–11th gen), Accord (9th–10th gen), CR-V (4th–5th gen), HR-V (2nd gen), Fit/Jazz (3rd gen), Odyssey (5th gen), Pilot (3rd gen), Passport (3rd gen), and Ridgeline (2nd gen).
