This code means there's a problem with the wires or connections that help control the car's parking brake. It's like when a toy's remote control doesn't work because the wires inside are loose or broken.
The C0615 code is triggered when the park brake control module detects an open or faulty circuit in the control wiring.
The Park Brake Control Module is responsible for managing the electronic parking brake system. The C0615 code indicates that there is an open circuit or a failure in the control circuit of the park brake control module. This can prevent the electronic parking brake from engaging or disengaging properly.
