There are many different ways that PGN message definitions are documented. The examples below show typical ways that parameters in the PGN 65263 Engine Fluid Level/Pressure message may be documented. The SAE J1939-71 specification contains the definitions for all standard PGNs. The PGN specifications appear similar to the following representation:

2024年8月1日 · Commonly Used PGN in SAE J1939 Diagnostic Messages in SAE J1939. Diagnostic messages are crucial for monitoring and troubleshooting vehicle systems. Some commonly used diagnostic PGNs include: PGN 65226 (DM1 – Active Diagnostic Trouble Codes): Transmits active diagnostic trouble codes from the ECUs.

• Actual Engine – Percent Torque (PGN 61444, SPN 513) • Engine Coolant Temperature (PGN 65262, SPN 110) • Wheel-Based Vehicle Speed (PGN 65265, SPN 84)

PGN (CAN ID [hex]) Message SPN Byte Resolution, Offset Range Direction Period 61444 (0x0CF00400) Electronic Engine Controller #1: EEC1 TX/RX 10ms ... 65263 (0x18FEEF00) Engine Fluid Level / Pressure #1: EFP1 TX 500ms MASTER Fuel Delivery Pressure 94 1 4kPa /bit, 0kPa 0 to 1000kPa

2025年1月8日 · 具体可以通过查询SAE J1939相关的PGN、SPN、SLOTS、源地址等信息查询表或者在SAEJ1939-71文档里面直接搜索，查看到相关信息后，代入下面公式计算。 解析值=原值*分辨率+偏移量（用于接收） 原值=（解析值-偏移量）/分辨率（用于发送） 在查询中搜索“61444” SPN是190,对应Engine Speed,查看分辨率【Resoultion】每一个bit位代表的是0.125转，偏移量【Offset】是0，SPN在PGN的位置【SPN Position in PGN】是4-5，代表第4和第5字节代表转 …

Running a BridgeWay with a Common Parameters configuration is as simple as generating and loading the configuration into a BridgeWay module and establishing communications to it from the required controller. Power on the BridgeWay module. Connect the USB configuration cable from the PC to the BridgeWay and start BWConfig 2.0.
