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

Isuzu P0328

Basic error definition

CAN-H, Low Speed Network. Faulty Signal

Cause of DTC

The central electronic module (CEM) checks the voltage in CAN L and CAN H on the low speed network. The diagnostic trouble code (DTC) is stored if the central electronic module (CEM) registers a short-circuit between CAN L and CAN H in the low speed network. The diagnostic trouble code (DTC) can be diagnosed when the ignition has been on for at least 10 seconds. Note! If DFxx diagnostic trouble codes (DTCs) are stored the central electronic module (CEM) must not be replaced as the diagnostic trouble code (DTC) indicates a short-circuit in one or more conductors in the Control area network. The central electronic module (CEM) is the only control module that monitors the voltage level in the Control area network wiring. The central electronic module (CEM) is therefore the only control module that can store a diagnostic trouble code (DTC) for a short-circuit in one of the cables to ground or supply voltage. Do not replace the central electronic module (CEM) in the event of a CAN fault unless VIDA fault-tracing has indicated that the central electronic module (CEM) has an internal fault. The diagnostic trouble code (DTC) can be diagnosed when the ignition has been on for more than 10 seconds.
