DTC 1628- CAN Address Conflict Failure
• CAN device(s).
• Check Condition- Key On, Engine on.
• Fault Condition- two or more devices on the network
that contain the same SA.
• Corrective Action(s)- Sound audible warning or illumi-
nate secondary warning lamp.
• Non-emissions related fault.
The Controller Area Network serves as a communication
portal between intelligent devices. These devices may be
but are not limited to other engine ECMs (slave), diagnos-
tic tools, “smart” gauges, “smart” sensors, powertrain
control units, vehicle controllers, actuators, etc. The net-
work permits several devices to communicate with each
other receiving and broadcasting commands as pro-
grammed. This type of network allows devices to be
added to an entire system through only two conductors
and permits all other devices to broadcast and receive
commands to and from the device when properly com-
manded.
This fault indicates there are two (2) or more devices on
the network that use the same source address.
