USER MANUAL

Current Data -----------------------------------

II.
(= Data Stream, Live Data, Service Data)
A. Pulse Signal Type
a. Data stream is not generally supported for this type of old cars because the
speed of pulse signal communication is too slow to read the data stream
variables.
b. Some of old Toyota cars using 17-pin rectangular adapter exceptionally
support data readings as the system supports relatively high speed pulse
signal communication.
B. Serial Communication Type
a. Most of control systems with serial communication support data stream
function. Select [Current data] from the menu, then the data readings follow.
b. Some systems like SRS or ABS may be designed not to support data stream
on purpose by the car manufacturer while the other systems are supported.
A scanner is a passive tool that reads information from the control system,
and it is unable to actively generate information that the system does not
provide.
c. Some old OBD1 generation Korean and European cars equipped with Bosch
control system that communicates in ISO9141 protocol provide relatively
slower communication speed. Data sampling may seem slow with these
cars
