DTC Descriptor

DTC C0000 71: Vehicle Speed Information Circuit Invalid Data

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 serial data message. Modules connected to the high speed CAN circuit monitor for the vehicle speed information.

Conditions for Running the DTC

System voltage is between 9-16 V.

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

The electronic suspension control is disabled for the duration of the ignition cycle.

Conditions for Clearing the DTC

A current DTC clears when the diagnostic runs and passes.

Circuit/System Verification

Drive the vehicle in a straight line at a speed greater than 40 km/h (25 mph).
Verify all scan tool Wheel Speed Sensor parameters are within 1.6 km/h (1 mph) of each other.

⇒	*If any parameter is not within 1.6 km/h (1 mph) of each other*

Refer to Circuit/System Testing.

⇓	*If each parameter is within 1.6 km/h (1 mph) of each other*

All OK.

Circuit/System Testing

Ignition ON.
Verify that DTC C0035, C0040, C0045, or C0050 is not set.

⇒	*If any of the DTCs are set*

Refer to Diagnostic Trouble Code (DTC) List - Vehicle .

⇓	*If none of the listed DTCs are set*

Replace the K19 suspension control module.
Verify the DTC does not set while operating the vehicle.

⇒	*If the DTC sets*

Replace the K17 electronic brake control module.

⇓	*If the DTC does not set*

All OK.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the repair.
