DTC Descriptor
DTC C0563 00
- Calibration Read Only Memory (ROM) Checksum Error

Circuit/System Description

The electronic brake control module (EBCM) communicates with the engine control module (ECM), body control module (BCM) and instrument panel cluster (IPC) to correlate the correct calibrations are programmed in the EBCM.

Conditions for Running the DTC

Ignition voltage is greater than 9.6 volts.

Conditions for Setting the DTC

The EBCM has been improperly programmed.

Actions Taken When DTC Sets

* The EBCM disables the ABS and the TCS for the duration of the ignition cycle.
* The ABS indicator turns ON.
* The TC indicator turns ON.
* The VSES indicator turns ON.

Conditions for Clearing the DTC

* The condition for the DTC is no longer present.
* The electronic brake control module (EBCM) automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.
