U2100 on Lincoln by model: symptoms, diagnosis and fix

Some 2020-2023 Aviators equipped with air suspension may display a Drive Malfunction and/or Suspension Fault message with DTCs B1041 and U2100 stored in Suspension Control Module A (SUMA). Ford SSM 51621 says this bulletin-defined condition can occur when SUMA enters diagnostic service mode after an on-demand self-test following suspension diagnosis or repair. It does not identify a leaking air spring, compressor, height sensor, or solenoid as the cause of these two codes.

Common Symptoms

  • Drive Malfunction message
  • Suspension Fault message
  • DTC B1041 stored in SUMA
  • DTC U2100 stored in SUMA

How to Fix

Use Ford Diagnosis and Repair System (FDRS) and select SUMA > Run All CM (Continuous Memory) DTCs. Do not run SUMA > OD and CM DTCs for this condition because the on-demand self-test can create the invalid codes. If that test was run, clear the condition with SUMA > Transport and Factory Mode Deactivation. If other DTCs or physical ride-height symptoms remain, follow Workshop Manual Section 204-05 normal diagnostics before selecting a part.

Owner tips & cautions

  • WarningDo not replace a compressor, air spring, sensor, or solenoid from B1041/U2100 alone; SSM 51621 first corrects a diagnostic service-mode state.
  • TipAsk whether an on-demand SUMA self-test was run immediately before the warning appeared and retain the complete FDRS fault report for any remaining diagnosis.
