U045E Invalid Data Received From Automated Driving System Control Module B

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.

Likely causes

Ethernet cable routed too tight, straining plugs and pins at the ADAS modules
Harness clip at the ADAS decision module outside the specified distance
Internal fault of ADAS control module B

Symptoms

  • Blind spot alert unavailable message
  • Blind spot lamps in the mirrors stay lit
  • Driver assistance features disabled
