Code C1274 Hyundai Description

The 4WD vehicle measures the G-sensor signal to solve for 4WD vehicle unique problems.

The HECU uses a filtered signal, as a supplementary value, to determine the road friction coefficient. This value is used for the accurate calculations of assumed vehicle speed, or precise division of control starting points.
