Variable Effort Steering Circuit Operation for Chevrolet Corvette 1999

When the Electronic Brake Traction Control Module (EBTCM) commands the Magnasteer Actuator ON, B+ is supplied through the EBTCM connector terminal C to the MAGNASTEER actuator connector C107 terminal A. Ground/control for the MAGNASTEER actuator is provided through the EBTCM connector terminal F to MAGNASTEER actuator connector C107 terminal B. The EBTCM controls the amount of current supplied to the MAGNASTEER actuator based on the input from the wheel speed sensors.
