U0347 Software Incompatibility With Hybrid/EV Battery Interface Control Module N

N, the fourteenth slot, is not tied to any vehicle in public sources. What can be shown is how false mismatch codes arise in the workshop. Volvo notes for its electric VNR that many apparent data mismatches come from TEA2+ control units not reporting to the tester; switching the truck on and letting it power up, then starting and logging into the tool, and only then plugging in the interface avoids them. Ford reports for 2012–2018 Focus Electric that U0130 can follow a battery pack replacement unless the programmable module installation is run, which flashes PCM and TCM for battery compatibility, and that reusing an old tester session can add U1030. A code for N is best judged after a clean session. U01AD and U04AE are its neighbours.

Likely causes

Stale or incorrectly started tester session reports a false mismatch
Programmable module installation skipped after a battery replacement
Board N really carries incompatible software

Symptoms

  • Code appears during or right after a tester session
  • Further network codes in the battery controller
  • Often no change in driving once programming is completed
