Most Reported On
B2477 is an OBD-II diagnostic trouble code meaning “Module Configuration Failure.” This body code means a control module's vehicle-specific configuration data (its 'as-built' programming tied to the VIN and installed options) is missing, incorrect, or corrupted. It most commonly appears after a module such as the body control, ABS, or instrument cluster is replaced and not properly programmed, or after a software/configuration glitch. It is a programming/data fault rather than a mechanical failure, and is usually cleared by reprogramming the module with the correct configuration using a capable scan tool. This code is most commonly reported on 2015-2020 Ford Transit, and 2003-2011 Lincoln Town Car (Executive, Signature, Cartier, Designer, Signature L), with repair costs ranging from $80 to $1,200.
