- How the car detects it
- Automated driving system control module A is a computer that merges radar and camera data and plans braking and steering for features such as adaptive cruise, lane centring and emergency braking. U045D means a partner hears it but gets implausible content; U015C is lost contact. Stellantis documents the code. Its TSBs 08-256-25 through 08-259-25 (Dodge Charger and Jeep Wagoneer S, model years 2024-25, Active Driving Assist) require a MIL together with U015C-00 or U045D-00, often with an emergency braking unavailable message; the fix is new software for the front long-range radar, rated at 0.2 h. STAR case S2508000095 for 2024-26 Wagoneer and Grand Wagoneer shows the CADM2 storing U045D-00 with a freeze frame about an unexecuted brake jerk request, traced to strained Ethernet cables. Assistance features switch off until repair.
