This may be due to the software in the HPVCM. To correct the condition, reprogram the HPVCM using the latest software level of the Ford Diagnosis and Repair System (FDRS). If the DTC remains this may be due to the \"Heat Pump Vacuum Lock Release Sequence\" application performance in the Ford Diagnosis and Repair System (FDRS). The \"Heat Pump Vacuum Lock Release Sequence\" application has been updated in FDRS to operate properly. For claiming, use causal part 14H266 and labor operations 12651D and 12651D4.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11032686-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11032686-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11032686","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"engine","name":"Engine","parent":null},{"id":"fuel-system","name":"Fuel system","parent":null}],"codes":["B1717"],"topics":[],"vehicles":[{"make":"FORD","model":"F-150 LIGHTNING BEV","year_from":2024,"year_to":2024,"match":"base","vehicle_ids":["2024_ford_f-150"]},{"make":"FORD","model":"MUSTANG MACH E","year_from":2025,"year_to":2025,"match":"exact","vehicle_ids":["2025_ford_mustang-mach-e"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
