This is the process of activating the OBD system is starting communication. Commonly used physical layers [ edit ] One underlying physical layer used for KWP is identical to ISOwith bidirectional serial communication iso 14230-2 a single line called the K-line.
The address iso 14230-2 contains the functional address of the OBD system. Views Read Edit View history. Retrieved 10 May In addition, there is an optional L-line for wakeup.
ISO and ISO INITIALIZATION and DATA TRANSFER – EverythingHere – 博客园
For K-only initialization the port is configured at 5 baud rate; the address byte is sent; ms pause iso 14230-2 baud rate is restored to 10, baud. All subsequent communications are using this iso 14230-2 rate. Retrieved from ” https: A Guide for the Penetration Tester. The transfer timing is very important and is determined by the periods Iso 14230-2 with specified maximal and minimal allowable values. This protocol covers jso application layer in the OSI model of computer networking.

This technology-related article is a stub. A system timer for ms 5-baud bit time is ixo. The initialization can be started after an idle-time on the bus. Two types of initialization can be used: Iso 14230-2 period P3max has value of ms. Both of these wakeup methods require timing critical iso 14230-2 of the K-line signal.
iso 14230-2 The isoo initialization begins with wake-up pattern WuPtransmitted by the tester simultaneously on K and L lines. When implemented on a K-line physical layer KWP requires special wakeup sequences: This is implemented in iso 14230-2 ways in initSlow method. One underlying physical layer iso 14230-2 for KWP is identical to ISOwith bidirectional serial communication on a single line called the K-line. This message uses functional addressing and contains the target address of the Iso 14230-2 system and the source address of the tester.
The Car Hacker’s Handbook: This initialization starts with sending of 5-baud address byte from the tester client to the OBD system server.
KWP can be implemented on CAN using iao the service layer and session layer no header specifying length, source and target addresses is used and no checksum is iso 14230-2 ; or using all layers header and checksum are encapsulated within a CAN frame.
You can help Wikipedia by expanding it. KWP also covers the session layer iso 14230-2 the OSI model, in terms of starting, maintaining and terminating a communications session.
The timing is implemented by using system timer for wait function and by using iso 14230-2 read timeouts. Iso 14230-2 data rate is between 1. After that time the communication link is automatically terminated by the server. CAN is becoming an 144230-2 popular alternative to K-line because the CAN bus is usually present in modern-day vehicles and thus removing the need to install an additional physical cable.
After sending the pattern, the server sends two keywords KW which carry information about the form of the subsequent serial communications. This page was last edited on 10 Mayat iso 14230-2 This is referred 114230-2 as data transfer and is performed by the transfer method.
