Circuit/System Description



The wheel speeds are detected by active wheel speed sensors. Each wheel speed sensor receives a 12 V reference voltage from the electronic brake



control module (EBCM) and provides an alternating current square wave signal to the EBCM. As the wheel spins, the EBCM uses the frequency of



the square wave signal to calculate the wheel speed. The EBCM sends the wheel speed information as a high speed controller area network (CAN)



serial data message.



Conditions for Running the DTC



Ignition ON



Conditions for Setting the DTC



A supervised periodic message that includes the wheel speed serial data has not been received.



Action Taken When the DTC Sets



Specific subsystems will not function or operate in degraded mode.
