DTC Descriptor

DTC C0201: 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

•	The EBCM detects an open in the battery positive voltage 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)/dynamic rear proportion (DRP)/Vehicle Stability Enhancement System (VSES) for the duration of the ignition cycle.

•	The ABS indicator turns ON.

•	The Traction Control indicator turns ON.

•	The driver information center (DIC) displays the SERVICE ABS/TRACTION message.

•	The DIC displays the PANIC BRAKE ASSIST message.

Conditions for Clearing the DTC

•	The condition for setting the DTC is no longer present and the DTC is cleared with a scan tool.

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

Circuit/System Verification

With the scan tool, access the ABS special functions menu and perform the ABS Motor test. The pump motor should function and no DTCs should be set.

Circuit/System Testing

Test for an open or a short to ground in the solenoid valve battery positive voltage circuit terminal. Verify no open or a short to ground is found.

⇒	If open or a short to ground is found repair circuit.

Replace the EBCM/brake pressure modulator valve (BPMV) assembly.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
