Error code B2601 is very broad in scope. It indicates an issue with your car’s shift position. This means that the Body Control Module (BCM) has detected a difference between the P-shift input signal and the shift position signal it receives from the Intelligent Power Distribution Module (IPDM E/R). This information is processed through the CAN (Controller Area Network) communication center.

These are lights installed on most modern vehicles. They’re bright but low-powered lights that always operate while your car is running. The BCM controls the DRL relay.
The spark control of the relay takes in the positive ignition voltage, while the BCM grounds the control circuit. This helps activate the relay. If the control circuit is faulty and causes some odd conditions due to a short in the ground, error code B2601 will be displayed.
