OBD-II code C0560 indicates that the brake pressure sensor has not been calibrated or the calibration data is missing or corrupted. This calibration is necessary for the vehicle's electronic stability control (ESC) and anti-lock braking system (ABS) to function accurately.
If the brake pressure sensor was recently replaced or the brake system was serviced, the sensor may not have been recalibrated, triggering this code.
A defective brake pressure sensor may fail to retain or communicate calibration data, leading to the code being set.
Voltage spikes, poor electrical connections, or wiring damage can corrupt the calibration data stored in the sensor or module.
A temporary software error in the ABS or ESC module may cause it to lose or misinterpret calibration data, though this is less common.
While rare, a failure in the ABS or ESC control module could result in the inability to store or process calibration data. This is typically a last-resort diagnosis.
While the vehicle may still be drivable, the ESC and ABS systems may be disabled or impaired, reducing safety during braking or slippery conditions. Address the issue promptly.
Recalibration typically requires a scan tool with the appropriate software and following the manufacturer’s specific procedure. It is not usually a DIY task unless you have the proper tools and guidance.
Replacing the control module is rarely the solution for this code. The issue is almost always related to the sensor itself, its calibration, or electrical connections. Only consider module replacement if all other causes are exhausted.
This is usually incorrect. The powertrain control module (PCM) is not directly involved in brake pressure sensor calibration or ESC/ABS operation. The code pertains to the brake system and its sensors, not the engine computer.
