Code B3006 2015 Chevrolet Silverado Description
The B3006 code specifically pertains to the Hood Ajar Switch Circuit in the 2015 Chevrolet Silverado. This diagnostic trouble code (DTC) indicates that the vehicle's Body Control Module (BCM) has detected a malfunction in the hood ajar switch circuit. The hood ajar switch is a critical component that informs the vehicle's electronic systems whether the hood is securely closed or not. If the switch is faulty or the circuit experiences an open or short condition, the BCM will trigger this code.
