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.

Likely causes

Module not fitted on this build, code without fault (Ford Transit 2026)
GPS or telematics unit without power or ground
Bus wiring or connector at the receiver faulty
GPS module faulty

Symptoms

  • Navigation shows wrong or no position
  • Telematics or emergency call reports location unavailable
  • Clock or compass no longer updated by satellite
