Diagnostic Trouble Codes (DTCs) are standardized codes used by vehicle manufacturers to identify and diagnose issues within a vehicle's onboard computer system. These codes are generated when a vehicle's onboard computer, also known as the Engine Control Module (ECM) or Powertrain Control Module (PCM), detects a problem or anomaly in the vehicle's systems.

The B166A60 code is related to the vehicle's body control module (BCM) and is classified as a " Body Control Module Fault" code. The BCM is responsible for controlling various body functions, such as lighting, wipers, and door locks.
