ABS Controller Interaction With Traction Control

The ABS controller takes the average of the two front wheel speeds minus the average of the two rear speed sensor inputs and calculates wheel slip. It then determines the status of the TC switch and communicates this data to the PCM initiating spark control. The ABS controller also turns the TC LED On or Off depending on the command from the PCM.
