Code C2366 Description

The C2366 code refers to a TCS (Traction Control System) Valve Primary USV1 error. This code indicates a malfunction in the primary valve of the TCS system, which is responsible for controlling the distribution of hydraulic pressure to the brakes in order to prevent wheel slip during acceleration or braking. When this valve fails to operate correctly, it can lead to issues with traction control, stability control, and overall vehicle performance.
