This post will introduce how to use Launch SmartLink B and SmartLink C to clear fault codes that appear after replacing the steering gear on a 2018 Maserati.
Procedure:
Simply connect your diagnostic interface to start SmartLink B, which will automatically detect the vehicle model.
Click ‘Continue’ to allow the sophisticated diagnostic equipment to run a quick test across every control unit.
Once the full-system scan is finished, go directly into the EPS system.
Because the steering gear was replaced, you need to access its specific control unit.
Here, you can check for Diagnostic Trouble Codes (DTCs).
Without proper matching, two DTCs will likely be logged—one for a mismatch and another for a steering angle fault.
These can be cleared systematically via dedicated programming and matching routines.
By following these steps, the issue is completely resolved using Launch SmartLink C and SmartLink B, evident by the clean bill of health with no active DTCs.
