This code means there's a problem with the car's system that helps prevent the wheels from slipping when you drive. It's like when you try to run on a slippery floor, and you need to be careful not to fall.
The code C008A indicates an issue with the Traction Control System (TCS) mode control, which helps manage wheel slip during acceleration.
The C008A code is triggered when the vehicle's TCS detects a malfunction in the mode control circuit. This could be due to faulty wiring, a malfunctioning TCS switch, or issues with the TCS control module.
