Most Reported On
B1001 is an OBD-II diagnostic trouble code meaning “Option Configuration / Module Configuration Error (Manufacturer-Specific).” B1001 is a manufacturer-specific body code that, on GM-family vehicles, generally indicates an option/configuration error — a control module (often the airbag/SDM or another body module) finds that its programmed configuration does not match the vehicle or the data it expects. It is most often a setup/programming issue that appears after a module is replaced or reprogrammed rather than a hardware failure. Confirmation requires a make-specific scan tool and service information. This code is most commonly reported on 2004-2007 Chevrolet Malibu, with repair costs ranging from $300 to $1,200.
