The Workshop Manual, Section 412-00 pinpoint test J has been updated to aid in proper diagnosis. This may be due to the heating ventilation and air conditioning control (HVAC) module software. Recommend the customer to use AUTO Mode and adjust the temperature to maximize heater performance. This does not affect vehicle durability and no additional diagnosis or service is required at this time. Inform customers they can continue to drive the vehicle and engineering is currently working on a solution for this condition that is expected in late April 2022. Replacement or reprogramming of the HVAC will not resolve this condition. Monitor OASIS for additional information and schedule service appointments for customers once the repair becomes available.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10210228-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10210228-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10210228","components":[{"id":"engine","name":"Engine","parent":null},{"id":"equipment","name":"Equipment and accessories","parent":null},{"id":"visibility","name":"Glass, wipers and mirrors","parent":null},{"id":"hvac","name":"Heating and air conditioning","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"MUSTANG MACH E","year_from":2021,"year_to":2022,"match":"exact","vehicle_ids":["2021_ford_mustang-mach-e","2022_ford_mustang-mach-e"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
