From model year 1996, vehicles manufactured by Volkswagen AG are equipped with a Government required diagnostic system known as On-Board Diagnostics II (OBD II). This system monitors operation and function of all engine management system activity and automatic transmission operation to insure compliance with specified emission levels.

Vehicle emission levels are constantly monitored by the OBD II system and malfunctions are recognized and recorded. A Malfunction Indicator Light (MIL) in the instrument cluster alerts the driver to the fault and the need to have the system checked for fault codes. These codes follow a standard format and are known as Diagnostic Trouble Codes (DTCs) .

DTCs are assigned two codes. The first code is a numerical code assigned by the factory. The second code is referred to as a P-code and follows a structure required by law and defined by the Society of Automotive Engineers (SAE). This standard uses a letter to designate the system and four numbers to further identify and detail the malfunction as listed below.

First digit structure is as follows:

Pxxxx for powertrain ;

Bxxxx for body ;

Cxxxx for chassis ;

Uxxxx for future systems .

Second digit structure is:

P0xxx Government required codes ;

P1xxx Manufacturer codes for additional emission system function ;

Third digit structure is:

Px1xx measurement of air and fuel ;

Px2xx measurement of air and fuel ;

Px3xx ignition system ;

Px4xx additional emission control ;

Px5xx speed and idle regulation ;

Px6xx computer and output signals ;

Px7xx transmission ;

Px8xx transmission ;

Px9xx control modules, input and output signals .

The fourth and fifth digits designate the individual components and systems.

Explanation of general SAE Diagnostic Trouble Codes (DTCs):

System type:

Pxxxx = Diagnostic Trouble Codes (DTCs) for the drive ;

Standardized code:

P0xxx = Defined Diagnostic Trouble Codes (DTCs) with standardized DTC text according to SAE ;

P1xxx = Supplementary emissions relevant Diagnostic Trouble Codes (DTCs) provided by manufacturer ;

P2xxx = Defined Diagnostic Trouble Codes (DTCs) with standardized DTC text according to SAE, as of MY 2000 ;

P3xxx = Supplementary emissions relevant Diagnostic Trouble Codes (DTCs) provided by manufacturer, as of MY 2000 ;

System group:

Px0xx = Fuel and air measurements and supplementary exhaust gas control ;

Px1xx = Fuel and air measurements ;

Px2xx = Fuel and air measurements ;

Px3xx = Ignition system ;

Px4xx = Supplementary exhaust gas control ;

Px5xx = Speed and idling control ;

Px6xx = Control module and output signals ;

Px7xx = Transmission ;

Px8xx = Transmission ;

Px9xx = Control module, input and output signals .

LE : Pentru ca DTC codes sunt foarte multe , am postat acest document cu marea lor majoritate .
