Circuit Description

Speed sensor used on this vehicle is a single point magnetic pickup. This sensor produces an AC signal that EBCM uses to calculate wheel speed.

DTC sets when one of the following occurs:

• EBCM detects a deviation between the left and right rear wheel speeds of greater than 3.75 MPH at a vehicle speed of less than 62 MPH.
• EBCM detects a deviation between left and right front wheel speeds of greater than 6.25 MPH at a vehicle speed of less than 62 MPH.
• EBCM detects a deviation between left and right rear wheel speeds of greater than 6 percent of vehicle speed at greater than 62 MPH.
• EBCM detects a deviation between left and right front wheel speeds of greater than 2.5 MPH plus 6 percent of vehicle speed at greater than 62 MPH.

This DTC will set when EBCM cannot specifically identify which wheel speed sensor is causing malfunction. If EBCM can identify a specific wheel speed sensor causing malfunction, DTC associated with sensor (DTC C0035, C0040, C0045, or C0050) will be set.
