Some 2020-2021 Aviator vehicles equipped with air suspension may exhibit a Drive Malfunction and/or Suspension Fault message in the instrument panel cluster (IPC) with diagnostic trouble codes (DTCs) B1041 and U2100 stored in the SUMA. This may be due to the SUMA entering into a diagnostic service mode after an on-demand self-test or module replacement. If no other DTCs are present, use the latest software version of the Ford Diagnosis and Repair System (FDRS) scan tool to update and configure the SUMA. If other DTCs are present, refer to Workshop Manual (WSM), Section 204-05 for normal diagnostics. For claiming use causal part 5319 and applicable labor times found in Section 10 of the Service Labor Time Standards (SLTS) Manual.
