DTC Descriptor
DTC C0565 00
- Vehicle Identification Number (VIN) Information Error




Circuit/System Description

When the electronic brake control module (EBCM) is replaced, software and calibrations are flash programmed into the EBCM. The EBCM receives the vehicle identification number (VIN) information from other modules on the vehicle in order for the EBCM to automatically calibrate to the vehicle.


Conditions for Running the DTC

* The ignition is ON.
* Ignition voltage is greater than 8 volts.



Conditions for Setting the DTC

One or more of the following conditions are present:

* The incorrect EBCM is installed on the vehicle.
* The incorrect software or calibrations have been flash programmed into the EBCM.



Action Taken When the DTC Sets

* The EBCM disables the traction control system (TCS) until the DTC becomes a history DTC.
* The traction control off indicator illuminates.
* The driver information center (DIC) displays the SERVICE TRACTION SYSTEM message.
* The antilock brake system (ABS) remains functional.



Conditions for Clearing the DTC

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



Diagnostic Aids

If the DTC was set after EBCM replacement, verify that the replacement EBCM and software are correct for the vehicle.
