Viewing Live Data - Matco Tools FixAdvisor MD70 Operating Instruction

Live Data Mode

VIEWING LIVE DATA

The FixAdvisor is a special Scan Tool that communicates with the
vehicle's computer. The FixAdvisor lets you view and/or "capture"
(record) "real-time" Live Data. This information includes values (volts,
rpm, temperature, speed etc.) and system status information (open loop,
closed loop, fuel system status, etc.) generated by the various vehicle
sensors, switches and actuators.
In effect the FixAdvisor lets you view, in "real time", the same signal
values generated by the sensors, actuators, switches and/or vehicle
system status information used by the vehicle's computer when
calculating and conducting system adjustments and corrections.
The real time (Live Data) vehicle operating information (values/status)
that the computer supplies to the FixAdvisor for each sensor, actuator,
switch, etc. is called Parameter Identification (PID) Data.
Each PID (sensor, actuator switch, status, etc.) has a set of operating
characteristics and features (parameters) that serve to identify it. The
FixAdvisor displays this information for each sensor, actuator, switch or
status that is supported by the vehicle under test.
WARNING: If the vehicle must be driven in order to perform a
troubleshooting procedure, ALWAYS have a second person
help you. One person should drive the vehicle while the other
person observes the FixAdvisor data. Trying to drive and
operate the FixAdvisor at the same time is dangerous, and
could cause a serious traffic accident.
VIEWING LIVE DATA
1. While linked to the vehicle, start the engine,
then press and release the LD button.
2. Real-time Live Data (PID) information
supported by the vehicle under test
displays.
If Live Data is not supported by the
currently selected module, an advisory
message shows on the FixAdvisor's
display.
Remember, what you are viewing is
"real-time" Live Data. The values (volts,
rpm,
system status etc) for the various PIDS
displayed may change as the vehicle's
operating conditions change.
3. A vehicle usually supports several PIDs, however, only a limited
amount of PID data can be displayed on the screen at one time. If
additional PID data is available, a small arrow will be shown on the
display. Use the UP
scroll up or down to view all available PID data.
