See the basic definition of a diagnostic error. This will help you to clarify the main causes of the fault code. You will understand the program of the control unit
Basic DTC analysis according to OBD2 protocol standard.

OBD2 or On-Board Diagnostics displays messages for basic group styles. More comprehensible code composition has been standard since 2000. The DTC code consists of five characters and its composition will be shown in this video

Insight into programming

The basic unit for the operation of any computer is the bit. Logic 0 and 1 are expressed by a single bit. Diagnostics The error code is composed of 16 bits. The first two bits define one of the four basic circuits. The video will show you a comprehensive overview of the composition of the error report

A diagnostically understandable description of the Diagnostic Trouble Code

Ford P0885

Basic error definition

Configuration Fault. Faulty Configuration

Cause of DTC

The control module compares its configuration ID with the signal configuration transmitted on the control area network (CAN) by the central electronic module (CEM). If the configuration IDs do not correspond the fault code is stored. The diagnostic trouble code (DTC) is also stored if the communication between the electrical power steering module (EPS) and the central electronic module (CEM) is interrupted. Note! In the event of an open-circuit in both the control area network (CAN) cables, it is not possible to communicate with the electrical power steering module (EPS). Therefore it will only be possible to read off the diagnostic trouble code (DTC) if this type of fault is intermittent. When the diagnostic trouble code (DTC) is stored, the electrical power steering module (EPS) responds to the diagnostic command, however normal control area network (CAN) communication does not work. (Expulsion-mode).
