U016A code meaning
Lost Communication With Global Positioning System Module
What U016A means
U016A covers the global positioning system module, the receiver that supplies position, speed and time to navigation, telematics and emergency-call functions. Ford uses the code: its 2014 Boss 302S code list includes it, and SSM 54351 explains that 2026 Transit vans built without a telematics control unit may log U016A in the module Ford calls SOBDMC, alongside U0146 in the ABS module. Since nothing is fitted there, no repair is needed in that case. On vehicles that do carry the receiver, the usual causes are a lost supply or a bus fault at the module. Navigation then shows a wrong or frozen position and connected services may lose location data, while driving is unaffected and no MIL comes on. U046B is invalid GPS data.
U016A at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.2 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U016A
- Navigation shows wrong or no position
- Telematics or emergency call reports location unavailable
- Clock or compass no longer updated by satellite
Common causes of U016A
- PossibleModule not fitted on this build, code without fault (Ford Transit 2026)
- PossibleGPS or telematics unit without power or ground
- PossibleBus wiring or connector at the receiver faulty
- Less likelyGPS module faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U016A means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 6A | The exact fault in that area. |
What to do next
- Note U016A 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 U016A
What does U016A mean?
U016A means "Lost Communication With Global Positioning System Module". U016A covers the global positioning system module, the receiver that supplies position, speed and time to navigation, telematics and emergency-call functions. It is a generic code, so it means the same on every make.
Is it safe to drive with U016A?
U016A does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U016A fail an emissions test?
U016A 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 U016A to fix?
Difficulty: medium. A typical repair takes 0.2 to 2.5 hours of work. This is a job for a workshop.
Will U016A clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
