  • Erratic behavior may also include sudden braking or steering interventions without any apparent reason.

It is crucial to address any of these symptoms promptly to ensure the bci system functions correctly and helps you maintain road safety. Resolving a bci malfunction will require professional assistance from a reputable nissan service center.
