SAE J 3005-2014 Permanently or Semi-Permanently Installed Diagnostic Communication Devices.pdf

1、SURFACE VEHICLEINFORMATION REPORTJ3005 DEC2014Issued 2014-12Permanently or Semi-Permanently Installed Diagnostic Communication DevicesRATIONALESAE J3005 is being published as a new document as guidance for Remote I/M programs Portable Emission Measurement Systems (PEMS), GPS, Wireless-LAN or Bluetoo

2、th interfaces and insurance devices. The SAE J3005 devices are not intended to be used for SAE J1699-3 vehicle validation testing. The document focuses on OBD mandated communication protocols defined in SAE J1979. It is not the purpose of this document to preclude the use of non SAE J1979 proprietar

3、y protocols, PIDs, or connector pins used by vehicle manufacturers. Device manufacturers should check with vehicle manufacturer guidelines before using proprietary information.FOREWORDThe SAE J1962 connector was developed as a standardized connector for use in passenger cars, light duty, medium duty

4、 and heavy duty trucks which, since mandated in 2008 MY, utilize ISO 15765-4 as OBD protocol, to access on-board diagnostic information by “generic” test equipment. The access was anticipated to be for short term use in a controlled environment to facilitate a maintenance procedure, e.g., the “gener

5、ic” test equipment is installed in the vehicle in a workshop and is removed before the vehicle leaves the workshop.Over time, other devices are making use of the standardized connector and (SAE J1979) data in a more or less permanent installation to collect and use standardized data for purposes oth

6、er than a temporary maintenance procedure.There are some areas where this can be a problem:x If the vehicle is equipped with internal clients (e.g., telematics gateways, data loggers), these devices will prioritize requests made with the standardized OBD CAN IDs in order to fulfill the SAE J1979 tim

7、ing requirements. The internal clients will therefore not get the data they are supposed to store, possibly causing built in customer functions to stop working (updating information) as long as the external devices are connected.x If the attached devices send diagnostic services, this may disturb th

8、e vehicle functionality, e.g., sending a ClearDTC request while the engine is running may cause diagnostic monitors to make incorrect judgment (set DTCs) and warnfor overheated engine.x If the attached devices include a split-cable (i.e., a possibility to add, from the vehicle point of view) two ext

9、ernal devices may be connected at the same time utilizing the same CAN-identifier. If those devices do not detect thepresence of the other device and try to communicate at same time they may cause CAN collisions which will cause Bus off operations. The devices will also receive unsolicited messages

10、because they will see the responses for the request the other device has sent or no response since each ECU in the vehicle can only handle one request per time (i.e., if tool #1 has sent a request, the ECUs may not be able to handle a request from tool #2 before completing the first request).The int

11、ention of SAE J3005 is to provide guidelines to device vendors in order to minimize the risk of these problems._SAE Technical Standards Board Rules provide that: “This report is published by SAE to advance the state of technical and engineering sciences.

47、 device should not interfere with normal driving, i.e., the size must be such that it does not interfere with the vehicle operations or cause injuries during collision.4.2 Electrical RecommendationsThe device should adhere to the electrical requirements of the SAE J1962 connector and for CAN, the el

48、ectrical requirements in ISO 15765-4 and the electrical characteristics as defined in ISO 11898-2. The device manufacturer is recommended to respect the maximum cable length, the capacitance and the physical termination of the CAN bus. OBD defined pins in SAE J1962 are allowed to be used. The device

49、 vendor should utilize equipment with high Impedance for all other pins or contact the vehicle manufacturer.The device should go into a low power mode when the vehicle is in power save mode. When in this mode the device should not exceed an average current consumption of 100 A at 12 V permanent voltage (i.e., average wattage of 1.2 mW). There are a variety of methods that can be
