B1001 on Chevrolet
Option Configuration / Module Configuration Error (Manufacturer-Specific)
B1001 on Chevrolet vehicles indicates option configuration / module configuration error (manufacturer-specific). Au7o has documented this code across 1 Chevrolet model — most commonly on Malibu. 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. Typical repair costs on Chevrolet range from $300 to $1,200, depending on the specific model and root cause.
Common Causes of B1001
- •Module replaced but not programmed/configured to the vehicle
- •Incorrect or mismatched module software/calibration
- •Vehicle option configuration mismatch (RPO/VIN data)
- •Reprogramming interrupted or incomplete
- •Faulty control module
- •Wrong replacement part number installed
- •Data corruption from low voltage during programming

- Body Control Module and Instrument Cluster Electrical Faults Causing Gauges, Warning Lights, and Accessory Malfunctions2004-2007
Owners of the 2004-2007 Malibu frequently report erratic gauges, warning chimes, power door lock issues, retained accessory power problems, and intermittent no-crank or lighting anomalies tied to BCM or cluster-related electrical faults. Symptoms can appear randomly and may worsen with low system voltage, poor grounds, or internal module failure. In some cases the instrument cluster itself develops intermittent operation or false readings, while in others the BCM causes multiple unrelated body electrical complaints at once.
