Side obstacle detection modules are radar units that watch the blind spots and crossing traffic. Left and right units have their own codes, U0232 and U0233; letters C and D cover extra units. Ford names all four in SSM 51903 and its successors 53018 and 53569: SODL, SODR, SODCMC and SODCMD on 2021–2025 Ford and Lincoln models. After a module swap these units store U2100 when left unconfigured and U3002 when carrying another vehicle's VIN, and the VIN Write application in FDRS fixes it. U024E itself is in no public maker text; it is set by a module that consumes radar data, for example the cruise control or gateway module, when unit C stops sending. Bumper damage, a wet connector or a wrong replacement are likely triggers. Blind spot and cross-traffic alerts switch off with a message. D is U024F; invalid data from C are U054F.

Likely causes

Radar connector or harness in the bumper damaged, wet or corroded
Replacement or used module not configured for the vehicle
Radar module without power or ground
Radar module internally faulty

Symptoms

  • Blind spot system unavailable message
  • Blind spot and cross-traffic alerts missing
