U024F code meaning
Lost Communication With Side Obstacle Detection Control Module D
What U024F means
Module D is the fourth side radar in Ford's scheme beside SODL, SODR and SODCMC. Ford's bulletins list SODCMD among units that log U2100 or U3002 after replacement on 2021–2025 models; SSM 53569 adds that a VIN mismatch can also follow swapping a tail lamp from another car, and that radar modules cannot move between vehicles without programming. Which corner D covers is not published. No maker document uses U024F. It is set by a receiving module once D's frames stay absent. Wiring at the rear deserves a look first: GM found on 2013–2014 Enclave, Traverse and Acadia that the side object sensor harness rubbing on the muffler disturbed the whole LAN and set many U codes (PI1202). The driver sees a side assist warning and the affected zone unwatched. C is U024E; corrupt data from D are U0550.

Symptoms of U024F
- Side assist or blind spot warning message
- One monitoring zone without alerts
Common causes of U024F
- Most likelyRear radar harness chafed or heat-damaged near exhaust or bumper
- PossibleModule or tail lamp from another vehicle fitted without programming
- PossibleRadar module without power or ground
- Less likelyRadar module internally faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U024F means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 4F | The exact fault in that area. |
What to do next
- Note U024F and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about U024F
What does U024F mean?
U024F means "Lost Communication With Side Obstacle Detection Control Module D". Module D is the fourth side radar in Ford's scheme beside SODL, SODR and SODCMC. It is a generic code, so it means the same on every make.
Is it safe to drive with U024F?
U024F does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U024F fail an emissions test?
U024F is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is U024F to fix?
Difficulty: medium. A typical repair takes 0.3 to 3 hours of work. This is a job for a workshop.
Will U024F clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
