Code B23BD Dodge Description

The B23BD diagnostic trouble code (DTC) indicates a malfunction in the Stop/Start Disable Switch 1 Circuit in Dodge vehicles. This code is triggered when the vehicle's onboard diagnostic system detects a low voltage condition in the circuit responsible for the stop/start system. The stop/start system is designed to improve fuel efficiency by automatically shutting off the engine during idle periods, such as at traffic lights, and restarting it when the driver releases the brake. When the disable switch circuit registers a low voltage, it may prevent the stop/start system from functioning correctly, leading to the engine remaining active even when it would typically shut off.
