This summary uses the existing diagnostic information shown in full below.
The car's computer can't find the right settings for a sensor that helps the brakes work properly. It's like trying to play a video game without the right controller settings.
The vehicle's system has detected that the brake pressure sensor B is not calibrated correctly, which can affect brake performance.
The C059B code indicates that the Electronic Brake Control Module (EBCM) has detected that the brake pressure sensor B is missing calibration data. This sensor is responsible for monitoring the pressure applied to the braking system, and accurate calibration is crucial for the system to function correctly.
• ABS warning light on
• Reduced braking performance
• Unusual brake pedal feel
• Faulty brake pressure sensor B
• Corrupted or missing calibration data
• Wiring issues or poor connections
EBCM: Electronic Brake Control Module
ABS: Anti-lock Braking System
• Use a scan tool to check for any other related codes.
• Inspect the wiring and connections to the brake pressure sensor B.
• Check the calibration data for the sensor.
• Recalibrate the brake pressure sensor B using a scan tool.
• Replace the brake pressure sensor B if faulty.
• Repair or replace any damaged wiring or connectors.
• OBD-II scan tool
• Multimeter
• Calibration tool or software

Moderate
• Chevrolet Silverado
• GMC Sierra
• Cadillac Escalade
• Regularly check and maintain brake system components.
• Ensure proper calibration after brake system repairs.
• Perform routine diagnostics with a scan tool.
Sensor Issue
• Do not ignore the ABS warning light.
• Have brakes checked by a professional if you notice any issues.
• Regularly maintain your vehicle's brake system.
Check with the vehicle manufacturer for specific warranty coverage on brake components.
This code has been reported in vehicles with electronic brake control systems that require precise sensor calibration.
Moderate – While the vehicle may still be drivable, brake performance could be compromised, so it should be addressed soon.
Ignoring brake system warnings can lead to reduced vehicle safety and potential legal liability in the event of an accident.
• Vehicle must be on a level surface.
• Ensure the brake system is not under pressure during testing.
The brake pressure sensor B is typically located near the master cylinder or integrated into the ABS module.
Q: Can I drive with the C059B code?
A: While the vehicle may still be drivable, it is not recommended as brake performance may be compromised.
Q: How do I reset the calibration for the brake pressure sensor?
A: You will need a scan tool capable of performing sensor calibration procedures.
