: A weak or aging vehicle battery is a frequent culprit for "ghost" BSI errors, as low voltage can disrupt the sensitive electronics required for key identification.

: It frequently appears alongside other codes like B1808 (engine ECU immobilizer unlocking fault) or B1624 (protection unit relay faults). Common Causes

: The car may refuse to crank or start because the BSI is blocking the engine ECU due to an immobilizer mismatch.

The Peugeot fault code primarily indicates a failure in identifying the mechanical or electronic key (including hands-free remotes) within the vehicle's reader . This error is often logged by the Built-in Systems Interface (BSI) , which serves as the central control unit managing immobilizer functions. Understanding Fault Code B173D
