- Generic OBD-II code · Network
- Can trigger limp mode
- How the car detects it
- Control module B is the second unit of a split automated driving computer, and the two halves check each other. Stellantis documents U045E in STAR case S2508000095 for 2024-26 Jeep Wagoneer and Grand Wagoneer: the CADM and the global navigation and motion module store U045E-00 next to U015D-00, Ethernet link errors and time synchronisation faults, and the freeze-frame data name failed message checks on two internal processor paths. Replaced modules showed no defect; taut Ethernet cables had strained the plugs. Technicians inspect plugs and pins, replace the harness without splicing and set clip C121 to the specified distances. U015D would mean B is silent, U045D covers module A. Customers see a blind spot alert unavailable message, lit mirror warning lamps and switched-off assistance; this case names no MIL.
