This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks there's something wrong with the system that helps simulate how the brakes feel when you press the pedal.
The brake system simulator is a component that helps mimic the feel of traditional hydraulic brakes in vehicles, especially in those with electronic or hybrid braking systems.
The C1052 code indicates an issue with the brake system simulator, which is responsible for providing feedback to the driver to simulate the feel of a conventional braking system. This could involve problems with the simulator's sensor or actuator components.
• Unusual brake pedal feel
• Brake warning light illuminated
• Reduced braking performance
• Faulty brake system simulator sensor
• Wiring issues in the brake system
• Malfunctioning electronic brake control module

OBD-II: On-Board Diagnostics, a standardized system in vehicles for self-diagnostics and reporting.
• Scan the vehicle for additional trouble codes
• Inspect the wiring and connections to the brake system simulator
• Test the brake system simulator sensor for proper operation
• Replace faulty brake system simulator sensor
• Repair or replace damaged wiring
• Reprogram or replace the electronic brake control module if necessary
• OBD-II scanner

Brake System Issue
• Do not ignore the brake warning light
• Have the vehicle inspected by a professional if braking feels different
• Regularly check for software updates from the manufacturer
Check with your vehicle manufacturer; brake system components may be covered under the powertrain or specific component warranty.
This code has become more common with the advent of electronic and hybrid braking systems, which rely on simulators to provide traditional brake feel.
High – Brake system issues can affect vehicle safety and should be addressed promptly.
Driving with a malfunctioning brake system can be dangerous and may violate vehicle safety regulations.
• Vehicle stationary
• Engine running
The brake system simulator is typically located near the brake pedal assembly or integrated within the electronic brake control module.
Q: Can I drive with a C1052 code?
A: It's not recommended to drive with a brake system issue, as it can affect vehicle safety.
Q: How do I reset the C1052 code?
A: After repairs, use an OBD-II scanner to clear the code, but ensure the issue is resolved first.
