|What Does the P0724 Code Mean?

The stop light switch is part of a duplex system that transmits two signals: STP and ST1-. These two signals are used by the Engine Control Module (ECM) to monitor whether or not the brake system is working properly. This Diagnostic Trouble Code (DTC) indicates that the stop light switch assembly remains on. When the stop light switch assembly remains on during STOP and GO driving, the ECM interprets this as a fault in the stop light switch assembly. Then the ECM illuminates the MIL and stores the DTC.
