Diagnostic Instructions
DTC Descriptor
DTC C0268: Class 2 Data Error Reported
Circuit/System Description
The electronic brake control module (EBCM) disables the traction control when other electronic control modules set DTCs for components that affect the operation of the traction control system.
Conditions for Running the DTC
The ignition switch is in the ON position.
Conditions for Setting the DTC
The PCM or BCM diagnoses a condition preventing the engine control portion of the traction control function and sends a serial data message to the EBCM indicating that torque reduction is not allowed. The PCM or BCM and transmission will typically set
a DTC and the EBCM will set this DTC.
Action Taken When the DTC Sets
One or more of the following actions may occur:
| • | The EBCM disables the Antilock Brake System (ABS)/Traction Control System (TCS)/Vehicle Stability Enhancement System (VSES) for the duration of the ignition cycle. |
| • | DRP may be disabled and the Brake Warning indicator may turn ON. |
| • | Stability Caution indicator turns ON. |
| • | DIC displays the SERVICE STAB SYS message. |
| • | DIC displays the TRACTION FAILED message. |
Conditions for Clearing the MIL/DTC
| • | The condition for 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. |
