Q: What does code C05D7 mean?

Brake Transmission Shift Interlock (BTSI) Control Circuit. The C05D7 code indicates that the vehicle's computer has detected a fault in the electrical circuit that controls the Brake Transmission Shift Interlock (BTSI) system, which prevents the shifter from moving out of Park unless the brake pedal is pressed. The computer monitors the circuit for abnormal voltage or current and sets this code when the signal does not match expected values, often due to a wiring issue, a faulty solenoid, or a failed brake pedal position sensor.
