There can also be a maximum of 20 ECMs, or “nodes”, on the J1708 network. This is the primary protocol found on the 6-pin diagnostic connectors that were used from the early 1990s to the mid-2000s. It is recommended that the servicing technician be properly trained and familiar with the vehicle’s electrical system, J1939 data link, and electronic components before attempting any of the troubleshooting procedures in this Shorted to voltage troubleshooting – used when J1939 voltage is greater than 11 volts and is causing the entire data link to not communicate or communicate intermittently Shorted J1939 wires to each other troubleshooting – used when J1939 voltage is normal, but all components are not communicating. Otherwise, proceed to the next Test Step. troubleshooting from the beginning. It describes the two main data links: SAE J1587/1708 information link and SAE J1939 control link. The addition of CAN-based J1939 systems in the early 2000s Vehicles and equipment continue to get more complex with the addition of Just a few odds and ends to clear up and get,started in the right direction. ‪ Interesting that it has two different data link systems! The J1939 which basically runs the truck engine and transmission controls (and fortunate for me was not the issue or I would have been on the side of the road!) The second data stream is the J1587/J1708 which runs the smart guages, ABS, HVAC, and satellite systems. The BridgeWay will allocate this much space in the input data table for the DTC list. I The information is communicated over the data link. Controller Area Network (CAN) is a serial network technology that was originally designed for the automotive industry, especially for European cars, but has also become a popular bus in The SAE J1939 data link is electrically terminated at each end with a load resistor, which is commonly referred to as a ter-mination resistor. so the j1939 is the data link for all the on board computers to transfer messages via a 2 wire data link, so if you have a fault in the data link then computer communication will be interrupted sometimes will cause no starts and loss of certain function. DTC stands for Diagnostic Trouble Code and is a string of numbers that, when paired with FMI (Failure Mode Indicator) information, identifies the location and nature of a problem in a vehicle.
