DIAGNOSTICS
Diagnostic communications for all systems have changed to ISO-15765, CAN communications
protocol. This enhances communication speed and also allows for increased Select Monitor III
usage for diagnostics.
A new menu item, CAN diagnostics will be visible on the SMIII main menu. The CAN diagnostics
will be able to determine problems in the LAN/CAN circuitry, identifying lack of communications
from one part of the LAN/CAN to another.
