USING THE TABLET

OBD2 Diagnostics

FREEZE FRAME - $02

If more than one Diagnostic Trouble Code (DTC) was retrieved and to view Freeze Frame Data, following procedures

bellow:

1. From OBD2 Menu, select Freeze Frame - $02 and press the OK button.

n The Freeze Frame data displays.

n In OBD2 systems, when an emissions-related engine

malfunction occurs that causes a DTC to set, a record

or snapshot of engine conditions at the time that the

malfunction occurred is also saved in the vehicle’s

computer memory. The record saved is called Freeze

Frame data. Saved engine conditions include, but

are not limited to: engine speed, open or closed

loop operation, fuel system commands, coolant

temperature, calculated load value, fuel pressure,

vehicle speed, air ow rate, and intake manifold

pressure.

NOTE: If more than one malfunction is present that causes more than one DTC to

be set, only the code with the highest priority will contain Freeze Frame data. The

code designated “01” on the Tablet display is referred to as the PRIORITY code and

Freeze Frame data always refers to this code. The priority code is also the one that

has commanded the MIL (Check Engine) lamp on.

NOTE: Retrieved information can be uploaded to a Personal Computer (PC) with

the use of optional software (see instructions included with the software for more

information).

n To view a description of the displayed PID, press PID Desc.

LIVE DATA - $01

The Tablet lets you view “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. These are 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 Tablet for each

sensor, actuator, switch, etc. is called Parameter Identication Data (PID).

Each PID (sensor, actuator switch, status, etc.) has a set of operating characteristics and features (parameters) that

serve to identify it. The Tablet displays this information for each sensor, actuator, switch, or status that is supported by

the vehicle under test.
