DTC Descriptor
DTC C0558 4B
- Calibration Data Calibration Not Learned

Circuit/System Description

The electronic brake control module (EBCM) receives controller area network (CAN) serial data messages from other modules. The EBCM must be configured with the vehicle identification number (VIN), CAN configuration data and vehicle options. If not properly configured after installation, the EBCM may set a DTC.

The internal fault detection is handled inside the control module. No external circuits are involved.

Conditions for Running the DTC

Ignition ON.

Conditions for Setting the DTC

The EBCM is not programmed.

Action Taken When the DTC Sets

* The EBCM disables the traction control, stability control and hill start assist for the duration of the ignition cycle.
* The traction control/stability control-active indicator turns ON.

Conditions for Clearing the DTC

A current DTC clears when the diagnostic runs and passes.

Diagnostic Aids

A newly replaced EBCM can set one or more DTC on its initial ignition ON cycle.
