What it means (plain English)
The body control module, which manages various electrical components, is not set up correctly.
What the computer is actually seeing
The BCM detects a discrepancy in its configuration data, typically during startup or when a feature is activated.
What a healthy reading looks like
Configuration data should match the vehicle's VIN and module settings; discrepancies typically exceed 5% from expected values.
