SSM 54742

Some 2025-2026 Mustang GTD vehicles may set diagnostic trouble code (DTC) U0420:82 in the image processing module a (IPMA) during a diagnostic self-test. This may be due to the module's DTC sensitivity during vehicle key-on/start-up. Replacement or reprogramming of the IPMA module may not resolve this condition. If no other DTCs are present, no warning indicators are illuminated while the engine is running, and no noticeable symptoms are present, no additional diagnostics or service is recommended for this condition at this time. Inform customers engineering is currently working on a solution for this condition that is expected in Q2 2027. Monitor Professional Technician System (PTS) for additional information and schedule service appointments for customers once the repair becomes available. If this condition is encountered, use the "Submit Global Concern Report (GCR)" link at the upper right of the Vehicle ID tab to submit a report and reference this article number in the report.
