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. Some modules connected to the high speed CAN bus monitor for the wheel speed information. The DTC is set when the wheel speed information has not been received.

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.

Conditions for Clearing the DTC

A current DTC clears when the diagnostic runs and passes.

Circuit/System Verification

Ignition ON, observe the scan tool EBCM Wheel Speed Sensor parameters. The reading should be the same speed on all sensors when driving in a straight line at a speed greater than 20 km/h (13 MPH).

Circuit/System Testing


1. Ignition ON, verify that DTC C0035, C0040, C0045, or C0050 is not present in the EBCM.

2. If any listed DTC is present, refer to DTC C0035, C0040, C0045, or C0050 to diagnose that DTC prior to this diagnostic.

3. Replace the K17 Electronic Brake Control Module and verify the DTC does not reset.

4. If the DTC resets, replace the module that set the DTC.


Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
