51 MD Link- Operation MD Link- Overview The MD 200 Link Tester allows for diagnosing problems that may occur on the SAE J1587 or J1939 heavy-duty vehicle communication links. Several functions are included and they consist of Link Faults, Link Monitor, and Record Data. The MD Link Function system consists of: MD 200 Scan Tool PC to Scan Tool Cable PC-CBL-01 Scan Tool to 9-Pin Deutsch Cable SC-CBL-02 Scan Tool to 6-Pin Deutsch Cable SC-CBL-01 (J1587 only) Scan Tool to 3-Pin Deutsch Cable SC-CBL-03 PC Link Software for data extraction The link tester is designed to be an aid in diagnosing heavy-duty vehicle communication links. Always consult your OEM manufacture's troubleshooting or service manual for proper repair procedures. J1587 Link The SAE J1587 link is a low speed communication link that is designed to share information between electronic components installed on a vehicle. The rate of communication on the link is 9600 bits per second. This is much slower than the typical Internet dial-up rate, bits per second. The primary use of the communication link is for diagnostic purposes. This includes viewing fault codes, clearing codes, and viewing data such as engine speed, road speed, accelerator pedal position, etc. J1939 Link The SAE J1939 link is a high-speed communication link that is designed to share data and send control information between electronic components on a vehicle. This link is designed around CAN (controller area network). It is capable of providing data exchange (such as J1587) as well as providing a mechanism that allows one component to control another (i.e. automated transmission controls the engine during a shift sequence). The rate of communication is 250,000 bits per second, which is much greater than that of J

54 MD Link- Operation MD Link- Link Faults Overview The SAE J1939 communication link works off a protocol called CAN (controller area network). The hardware that supports this protocol contains a standard fault detection and monitoring system. This is in addition to any fault code or trouble codes that the component may report. The link tester will retrieve and display any CAN error codes that are being broadcast by the different components on the link. The J1939 link fault selection can also determine if the link is shorted or driven high. The SAE J1587 communication link does not contain a built in fault detection mechanism. However, the method used to send messages has a mechanism that checks to make sure that a message received contains the correct number of data points.

69 MD Link- Trouleshooting 13. You are looking at Msgs and Errors: If there are Msgs and no errors, the J1939 data link is working correctly with the components that are connected to the data link. Go to step 14. If there are Msgs and Errors, then there may be a problem with the J1939 data link. a. The J1939 data link (harness)- Look for loose connections, missing terminating resistors and damaged harnesses. b. An ECU/ECM is producing errors- An ECU/ECM is producing the errors. You can isolate which ECU/ECM is producing the errors. One by one disconnect an ECU/ECM from the J1939 data link. Example: Disconnect the Engine from the J1939 data link. View the MD-200 screen. Did the error go away? If so, the engine ECM is causing the problem, contact the Engine OEM. If not, reconnect the Engine ECM to the J1939 data link and disconnect the transmission ECU from the J1939 data link. View the MD-200 screen. Did the error go away? If so, the transmission ECU is causing the problem contact the Transmission OEM. If not, reconnect the transmission ECU to the J1939 data link and repeat this process for all components. 14. Press >MON<. 15. Using the arrow buttons, select Comm. Gap Test and press >ENTER<. 16. You will need to drive the vehicle for this test. Drive the vehicle in the same conditions that produced the problem. Example: Vibration, heat, water, etc. If a component is displayed check the J1939 data link that is connected to that component. Look for loose connections, missing terminating resistors, and a damaged harness. If the harness checks good then you will need to contact the OEM of the component that produced the Gap for further assistance. Link Tests and Errors- Using the MD-200 Link Tester in SCAN mode, check if there are any J1939 errors present. To do this, use the following procedure. 1. Connect the MD-200 to the vehicle using the 9-pin Deutsch cable. 2. Press the >POWER< button. 64
