To confirm a vehicle is built with a 10 channel DSP module, verify the minor feature code, F-150 (IDBBQ)/Expedition (IDBAP or IDBBR), by reviewing the build information by double-clicking the vehicle identification number (VIN) in the upper left corner in the Professional Technician System (PTS) website. To correct the condition, reprogram the DSP module to the latest software level using the Ford Diagnosis and Repair System (FDRS) diagnostic scan tool. For claiming, use causal part 18B849 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10243538-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10243538-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10243538","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"EXPEDITION","year_from":2022,"year_to":2023,"match":"exact","vehicle_ids":["2022_ford_expedition","2023_ford_expedition"]},{"make":"FORD","model":"F-150","year_from":2021,"year_to":2023,"match":"exact","vehicle_ids":["2021_ford_f-150","2022_ford_f-150","2023_ford_f-150"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
