- How the car detects it
- U015C points to automated driving system control module A, the computer that fuses camera and radar data for adaptive cruise, lane centring and emergency braking. Stellantis documents it in detail. In 2024-25 Dodge Charger and Jeep Wagoneer S with Active Driving Assist (TSB 08-256-25 to 08-259-25), MIL plus U015C-00 and U045D-00 call for new software in the front long-range radar. TSB 08-190-24 reflashes the Central ADAS Decision Module on early 2024 Wagoneer and Grand Wagoneer. Case S2508000095 (2026 Wagoneer) shows CADM2 logging U015C with an Ethernet link error, traced to tight cable routing. U015D is module B. Assistance features drop out and the MIL can light.
