What the code means
This is a manufacturer-specific code: the meaning depends on the make and sometimes on the year.
How to read C1277: the letter C means chassis (brakes, ABS, steering, suspension); the second digit 1 marks a manufacturer code whose meaning is set by the make; the last three characters 277 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.
