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 illuminate
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), diagnostic tools, “smart”
gauges, “smart” sensors, powertrain control units, vehicle con-
trollers, actuators, etc. The network permits several devices to
communicate with each other receiving and broadcasting
commands as programmed. This type of network allows
devices to be added to an entire system through only two con-
ductors 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.
