vad är skillnaden mellan OBD1 och OBD2 ?
What is the difference between OBD 2 and OBD 1? With OBD 1 each manufacturer used their own unique codes and definitions for identifying failures in the computerized engine management system.
This made it difficult on auto mechanics, servicing multiple vehicle brands. With OBD2 common codes and definitions were developed to identify all basic emissions related failures OBD 2 trouble codes consist of one alpha character followed by four digits.
The alpha character indicates the area of the vehicle were the failure occurred. This includes B for body, C for chassis, P for power train, and U for network.
The network would be considered a manufacturer specific code used only on a specific model or brand.
The body would include the airbag system or SRS codes. This includes all discriminating crash sensors, clock spring and the air bag deployment module.
The chassis would include ABS codes as well as suspension codes if the vehicle is equipped with active suspension.
The power train includes the transmission and engine codes. This is by far the most common system to set computer trouble codes.
The first digit of the diagnostic trouble code denotes the origin of the code. Check engine light codes authored by the Society of automotive engineers or, SAE are identified by zero.
