瀚慖f any of the DTCs are set, Refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic Trouble Code

Descriptions/Diagnostic Trouble Code (DTC) List - Vehicle).

2. With a scan tool, clear the DTC.

3. Test drive the vehicle while observing the scan tool Yaw Rate and Lateral Accelerometer Sensor parameter. The parameters should vary as

the vehicle changes directions.

瀚慖f the parameters are locked or erratic, replace the yaw/lateral accelerometer sensor.

4. Replace the EBCM.

Repair Instructions

Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.

* Vehicle Yaw Sensor with Vehicle Lateral Accelerometer Replacement (See: Brakes and Traction Control/Antilock Brakes / Traction

Control Systems/Yaw Rate Sensor/Service and Repair/Less than 3900 kg (8600 lb) GVW)

* Control Module References (See: Testing and Inspection/Programming and Relearning)for EBCM replacement, setup, and programming

DTC Descriptor

DTC C0201 00

- Antilock Brake System (ABS) Enable Relay Contact Circuit

Circuit/System Description

The solenoid relay, located within the electronic brake control module (EBCM), supplies battery voltage to all of the valve solenoids.

Conditions for Running the DTC

* Ignition voltage is greater than 9.5 volts.

* The solenoid relay is commanded ON.

Conditions for Setting the DTC

One or more of the following conditions exists:

* The EBCM detects an open in the B+ circuit to the solenoid valve relay.

* The EBCM detects a stuck open solenoid valve relay or an open circuit between the solenoid valve relay and solenoid valves.

Action Taken When the DTC Sets

* The EBCM disables the antilock brake system (ABS), traction control system (TCS) and vehicle stability enhancement system (VSES) for

the duration of the ignition cycle.

* The ABS indicator illuminates.

* The red Brake indicator illuminates.

* The StabiliTrak indicator illuminates.

* The driver information center (DIC) displays all wheel drive (AWD) OFF/Service Traction Control/Service StabiliTrak message.

Conditions for Clearing the DTC

* The condition for setting the DTC is no longer present.

* The EBCM clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.
