• Source Address (SA) = Last 8 bits of 29
29-Bit
Bit message identifier
• Source Address = address of transmitting ECU (node)
• A total of 254 addresses available
• Every address must be unique within network
• ECU’s CANNOT share address
• PGN’s are independent of Source Address
• Every ECU is allowed to transmit any message
NOTE:
The CAN standard in itself does NOT support node (ECU) addresses, only message ID’s.

SAE-J1939 - Network Management
• Network management defined in SAE J1939/81
• Handles auto allocation of node addresses per address claiming procedure
• Address claiming not supported per default in any other high level protocol
• Network Management identifies ECU
ECU’s
s and their primary function
• Node monitoring is not defined in J1939 – must be application specific
• J1939 d
does not support M

SAE – J1939 - Address Claiming
• 64-Bit name to uniquely identify nodes ( ECU’s)
• Necessitates unreasonable resources to maintain standard
communications
• Each ECU uses an 8-Bit address to identify the source of a message or to
access ((destination address)) another ECU in the network
• Address Claim Procedure:
• Designed to assign addresses to ECU
ECU’s
s right after the network startup
• Assuring that assigned address is unique to ECU
• SAE J1939 standard defines Preferred Address to commonly used devices in
order

SAE – J1939 - Address Claiming
Two possible scenarios:
Sending an address Claimed message ( Standard ):
• ECU sends Address Claimed message into the CAN bus
• ECU’s receiving address claim will record & verify claimed address with internal
address table.
• In case of address conflict ECU with lowest NAME value will succeed
• Remaining ECU’s must claim different address or stop transmitting to network
Request for Address Claimed message:
• Necessary procedure for ECU’s powering up late ( E.g. trailers, diagnostics tools, e.t.c. )
• Used to determine and claim available address or to find out which ECU’s are currently
on the network

SAE J1939 - Communications Methods
Destination Specific Communications:
• USE PDU1 (PF V
Values
l
0 tto 239 )
• Destination address required:
Broadcast Communications:
• Use PDU2 ( PF values 240 to 255 )
• Sending a message from a single or multiple sources to single destination
• Sending a message from a single or multiple sources to multiple destinations
Proprietary Communications*:
• Use
U either
ith PDU1 or PDU2
• CAN be either Destination Specific or Broadcast
• Use propriety PGN’s

0%.
• Using ‘limit mode’ allows the use of the retarder only up to the limit specified in the request.
This can be used to permit retarding of up to 50%, for example, if:• That limit is required by some device such as an EBS,
Or
• It can disable the use of the retarder by others, as when an ABS controller detects wheel slip.
