This code means there's a problem with the system that stops the car from shifting out of park unless you press the brake pedal.
The code indicates an issue with the electrical circuit that controls the Brake Transmission Shift Interlock (BTSI) system.
The Brake Transmission Shift Interlock (BTSI) system is designed to prevent the vehicle from shifting out of 'Park' unless the brake pedal is pressed. This code indicates a malfunction in the control circuit of this system, which could be due to electrical faults or component failures.
• Vehicle stuck in 'Park'
• Brake lights not functioning
• Check engine light illuminated
• Faulty BTSI solenoid
• Blown fuse in the BTSI circuit
• Damaged or corroded wiring/connectors
BTSI: Brake Transmission Shift Interlock
Solenoid: A coil of wire that acts as a magnet when carrying electric current, used in various applications including automotive systems.
• Inspect the BTSI fuse and replace if necessary.
• Check the wiring and connectors for damage or corrosion.
• Test the BTSI solenoid for proper operation.
• Replace the faulty BTSI solenoid.
• Repair or replace damaged wiring/connectors.
• Replace any blown fuses in the BTSI circuit.
• Multimeter
• Screwdriver set
• OBD-II scanner

Moderate
• Chevrolet Silverado
• Ford F-150
• Toyota Camry
• Regularly inspect brake light functionality.
• Ensure all electrical connections are secure.
• Avoid spillage of liquids near the gear shift area.
Electrical Circuit Issue
• Do not force the gear shift if stuck.
• Have the vehicle inspected by a professional if the problem persists.
Check with your vehicle manufacturer; some components may be covered under warranty.
This code has been more common in vehicles with automatic transmissions, particularly in models with electronic shift interlock systems.
Moderate – While the vehicle may still operate, it can be inconvenient and potentially unsafe if the vehicle cannot shift out of 'Park'.
Driving with a malfunctioning BTSI system may violate traffic safety regulations and increase the risk of accidents.
• Vehicle in 'Park' with engine running.
• Brake pedal pressed.
The BTSI solenoid is typically located near the gear shift mechanism, often under the center console.
Q: Can I drive with a C05D7 code?
A: It's not recommended as you may have difficulty shifting out of 'Park', which can be inconvenient and potentially unsafe.
Q: How can I reset the C05D7 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue persists, the code may return.
