U024E code meaning
Lost Communication With Side Obstacle Detection Control Module C
What U024E means
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.
U024E at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.3 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U024E
- Blind spot system unavailable message
- Blind spot and cross-traffic alerts missing
Common causes of U024E
- Most likelyRadar connector or harness in the bumper damaged, wet or corroded
- PossibleReplacement or used module not configured for the vehicle
- 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 U024E means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 4E | The exact fault in that area. |
What to do next
- Note U024E 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 U024E
What does U024E mean?
U024E means "Lost Communication With Side Obstacle Detection Control Module C". Side obstacle detection modules are radar units that watch the blind spots and crossing traffic. It is a generic code, so it means the same on every make.
Is it safe to drive with U024E?
U024E does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U024E fail an emissions test?
U024E 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 U024E to fix?
Difficulty: medium. A typical repair takes 0.3 to 3 hours of work. This is a job for a workshop.
Will U024E clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
