What the code means
The current SAE generic name is “Brake Pedal Position Sensor Supply Voltage Circuit Low”, but owner complaints point to a different component (see below). Older models and some makes use this code their own way, so check the meaning for your car in the make's service information.
How to read C056D: the letter C means chassis (brakes, ABS, steering, suspension); the second digit 0 marks a generic SAE code shared by all makes; the last three characters 56D identify the specific fault.
Electric power steering, steering angle sensor and steering column codes. After a front wheel impact the steering angle sensor often needs calibration, and a bent rack or tie rod produces errors scanners describe as invalid data.

What owners report
Excerpts of owner complaints in the original wording. Owner statements not verified by the regulator; personal data removed.
Nothing has happened yet, however, we just bought this vehicle and the Stabilitrack light came on 2 days after we bought it. We took it to a mechanic and it coded C056D, brake module hardware fault.
They found a rear differential module software issue 2810695. They found DTC C056D stored in rear diff control module. They programmed rear diff module and retested. Claim code is 1BYN199108119. I do not have any parts but I was told that they send warranty components back to the manufacturer for inspection.
I returned a couple hours later and the power steering had returned. The dealer found code C056D. They had to replace the rack and pinon assembly. I am the original owner of the truck and it has 38000 miles on it. The dealer reduced the repair cost from $1500 to $900.
