U3510 Control Module Missing Calibration

EmissionsNot relevant
Drive cycleNot required
Limp modePossible

U3510 says a control module lacks a calibration it needs: either the data set that adapts its software to the vehicle was never written or got lost, or a learned calibration such as a sensor alignment has not been done. CARB makes every emission-critical unit report a calibration ID and a verification number, so empty or invalid data cannot pass unnoticed. No maker publishes U3510 itself, but related codes show both meanings: Hyundai's chassis code C2702, worded the same way, appears on 2019 Elantra blind-spot radars (bulletin 19-BE-016H, new radar plus mounting-angle check), and Stellantis' C0529-00 for the steering angle sensor of the 2023 Dodge Hornet lit the MIL until the wheel was turned lock to lock (08-148-23, EPS update).

Likely causes

New or used module installed without programming or setup
Software update aborted, e.g. by low 12 V voltage or lost connection
Required learn or alignment routine not performed after repair
Internal memory of the module losing its stored data

Symptoms

  • Function of the affected module unavailable or limited
  • Warning lamp of the related system, MIL if the module is OBD-relevant
  • Fault appears right after a module replacement or software update
