6.2.3 Manual Protocol Selection
A communication protocol is a standardized way of data communication between an ECM and a
scan tool. Global OBD may use several different communication protocols. The scan tool
automatically connects to an available protocol, which displays on the connection message
(Figure 6-5). Some vehicles communicate on more than one protocol. Use the Manual Protocol
Selection option to switch to a different protocol.
Select Manual Protocol Selection and message displays advising you to make sure you know
the correct protocol for the test vehicle. An incorrect selection may activate warning lamps and set
CAN related faults on the vehicle. Select OK and a menu of options displays (Figure 6-7).
