DTC Descriptors
DTC C0574 08
- Circuit Board Temperature Sensor

DTC C0574 11
- Circuit Board Temperature Sensor Above Maximum Threshold

Circuit/System Description

The electronic brake control module (EBCM) monitors the internal temperature sensor.

Conditions for Running the DTC

* Iignition ON.
* The ignition voltage is greater than 10 volts.

Conditions for Setting the DTC

C0574 08

The EBCM detects an internal tempature sensor failure.

C0574 11

The temperature sensor value is greater than 284° F for greater than 1 second.

Action Taken When the DTC Sets

* The EBCM disables the antilock brake system (ABS), traction control and the vehicle stability enhancement system (VSES) for the duration of the ignition cycle.
* A DIC message and/or a warning indicator may be displayed.

Conditions for Clearing the DTC

* The condition for the DTC is no longer present.
* The EBCM clears the history DTC when a current DTC is not detected in 40 consecutive drive cycles.

Circuit/System Verification

Important: Diagnose all EBCM system related faults if C0574 goes to history after a 15 minute cool down period. Other faults may cause the circuit board to overheat.


Verify DTC C0574 is not set.

If DTC is set, replace the EBCM.

Repair Instructions

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