C1275 Description


The speed sensors detect the wheel speeds and send appropriate signals to the Skid Control ECU. Speed sensor rotors have rows of alternating N and S magnetic poles, and their magnetic fields change as the rotors turn. The speed sensors detect those magnetic changes and send pulse signals to the Skid Control ECU. The ECU monitors the wheel speeds through these pulse signals to control the ABS control system.
