Issuer (dept., name, phone, location, sign.) Date2003-11-03Appendix Insert Registration No.SubjectCAN Frames -EDC4 Category Uncontr.Reciever (name, dept., location)The CAN - BUS has the following adjustment:The node address of EDC4 is 0.The rate of transmission is 250 kBaudAfter switching power on EDC4 waits 10 sec for the other nodes before the time out diagnostic starts.During the 10 second after switching power on a receive message must be received 4 times at least, other wise there will be a time out error.When the power supply drops below 9Volt, EDC4 will admit the other nodes a time out of 30sec.A receive message can be missing 8 times in a row before a time out Error willbe generated.1. If a message of Torque Speed Control has generated the time out, theLimp Home Function will be started. If the message will be receivedagain it will not be accepted anymore by the EDC4 until the EDC4 isrestarted again.2. In case of other receive messages that generated a time out the lastreceived value will be used. If a message is received again it will beaccepted automatically.The node address for the received messages are 3. Only the request and engine stop request messages can be received from any node on the BUS. The priority, resolution, repetition rate and all other information is outlined in the CAN Specification for EDC4.Issuer (dept., name, phone, location, sign.)
