ID.4 utilizes open differential(s) for either the RWD or AWD. The TCS, ESC, EBD, EDL etc., are ABS brake-based that use 4-channel ABS sensors to read the speed differential between the pair wheels and front to rear axles.
Unlike the older, much simpler ABS System has the teeth cast on the hub, rotor, or a separate tooth-ring. The new-gen. ABS-based TCS, ESC, EBD, EDL etc., requires more precise differential speeds in each wheel and front to rear axle. This new-gen. ABS System has magnetic strips radially incorporated inside the wheel bearing on the outboard side of each wheel. Therefore, when the slightest wheel slip is detected regardless of the road condition, it generates the ESC or TCS light to blink momentarily until traction is regained. If the ESC or TCS light stays on, then there's a problem with the system. A code or codes will be generated. The use of an OBD II scanner will decode the trouble code(s).
