Circuit/System Description



Some control modules must be configured with specific software, serial numbers, vehicle options, or other information. If a control module was not



properly configured after installation that module may set DTC C056E. The symptom byte listed in the DTC Descriptor is for engineering reference



only. No external circuit diagnosis is involved.



Conditions for Running the DTC



Battery voltage is between 9-16 V and data link communications operate normally.



Conditions for Setting the DTC



The control module is not configured properly.



Conditions for Clearing the DTC



* A current DTC clears when the malfunction is no longer present.



* A history DTC clears when the module ignition cycle counter reaches the reset threshold, without a repeat of the malfunction.
