Circuit/System Description
The electronic brake control module (EBCM) disables the traction control system (TCS) and/or the vehicle stability enhancement system (VSES) when other electronic control modules fail to provide valid data necessary for the EBCM functionality. These other electronic control modules may or may not set DTCs for their invalid data.
Conditions for Running the DTC
The ignition is ON.
Conditions for Setting the DTC
The EBCM receives an invalid serial data message from another module. A faulty EBCM will not cause this fault.
Action Taken When the DTC Sets
| • | The EBCM may disable the TCS and/or the VSES. |
| • | 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 100 consecutive drive cycles. |
Diagnostic Aids
