Hello! Chevrolet Trailblazer 2 had its electric power steering (EPS) replaced with a different part number, 84494271. Will changing the calibrations from 84579653 (the original EPS) to 84494271 help? The VIN is registered, but error C056E occurs. The EPS needs to be calibrated after updating the calibrations? Thanks.

Yes, use the SPS setup and configuration to calibrate the EPS.

Okay, thanks! I have the DPS files with the necessary calibrations and a Type 4 file for the EPS configuration.

Yes, the type4 file should work.

The problem was solved. I updated the calibrations through the DPS, no adjustments were required, and the power steering worked without errors right away. Thanks everyone.
