On Board Diagnostics (OBD) is a term that refers
to the diagnostic and reporting capability of a vehicle. The first OBD
protocol was largely unsuccessful, but OBD-II has much greater
capability and standardization. The following steps will show how to
understand OBD-II codes and languages.
1. Recognize an Vas 5054a Original Version -II Diagnostic Trouble Code (DTC) as a 5-character code. The first character is a letter and the other four are numbers.
2. Interpret the first character
as the control system that set the code. The following letters are
assigned: B for Body, C for Chassis, P for Powertrain and U for
Undefined. Undefined codes are not used.
3. Examine the second character to determine the code type. The
digits 0, 1, 2 and 3 are used with 0 being a generic OBD-II code and 1
being an enhanced OBD-II code. The meaning of a 2 or 3 Vas 5054a Original Version varies by system
and is reserved for future use in powertrain codes. A 2 is reserved for
Original Equipment Manufacturer use and a 3 is reserved for Society of
Automotive Engineer use in body and chassis codes.
4. Use any digit from 0 to 9 for
digimaster 3 the third character of a DTC. This character
indicates the system or subsystem where the fault occurred and its
meaning varies according to the control system that set the code.
5. Study the fourth and Vas 5054a Original Version fifth characters of a DTC. These indicate the
operating conditions that caused the code and are specific to the
control system. The lowest number are general malfunctions with higher
numbers providing more specific information.
