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…

Some 2019 MKC vehicles without lane keep assist may exhibit an AdvanceTrac/hill start assist message(s) and/or illuminated electronic stability control/traction control indicator lamp with diagnostic trouble codes (DTCs) U0420 stored in the anti-lock brake (ABS) module and U0415 stored in the power steering control module (PSCM). This concern may also result in additional DTCs. DTCs U0420 and U0415 may have been set as a result of low system voltage during a vehicle start. The PSCM may have a communication fault with the ABS module when it reacts to low voltage when the key is on. To correct the condition, replace the ABS control module using the service part number KJ7Z-2C219-C. For claiming, use causal part 2C219 and applicable labor operations in Section 02 of the Service Labor Time…
