The traction control system uses the wheel speed sensors of the ABS (antilock brake) system but instead of releasing the brake of a wheel that is locking, uses a different programme to apply the brake of a wheel spinning under acceleration. I believe the ESC system is similar in principle but a more refined programme to increase vehicle stability.
Servicing the system is a specialist task requiring access to some sophisticated electronic equipment and somewhere in the process there should be an experienced thorough visual inspection of all the external components.

ESC is what some manufacturers call ESP.
