View Data
This function is used to view vehicle Parameter Identification Data (PID) in real time.
Apart from Read Codes, View Data is the most helpful diagnostic function for deter-
mining the cause of a driveability problem. View Data is most often used for observ-
ing sensor data and the ON/OFF states of switches, solenoids and relays.
NOTE: Multiple Responses to a PID Request - Vehicles equipped with more than
one on-board computer, for example a PCM and TCM (Transmission Control
Module), can respond with multiple results to a certain parameter identifi-
cation data (PID). In View Data, the OBD II Tester identifies the modules with
their manufacturer assigned names such as $10 or $1F by blinking the
module name near the end of the PID name. A PID that receives multiple
responses, such as Engine (RPM), will display on two lines.
To view your vehicles PIDs, select View Data
from the OBD II Function Menu and press the
ENTER key.
The OBD II System Tester will display the
generic OBD II PIDs supported for the vehicle
under test. Not all vehicles will have the same
PIDs. Do not worry this is normal. The PIDs
covered by the OBD II System Tester are
defined in Appendix B.
Press the BACK key to display the OBD II Function Menu.
NOTE: If you get an Operating Error message, make sure the DLC adapter cable is
securely attached and the ignition key is ON, then try again. If the problem
remains, refer to Section 4: On-Line Help and Trouble-Shooting Tips.
View Freeze Data
When an emission related fault is detected by the PCM the engine conditions are
recorded and stored in memory. This recording is known as a freeze frame. The
freeze frame is like a snapshot of the engine operating conditions at the time of a
fault. Freeze frame data can only be overwritten by another fault with higher priority.
The OBD II System Tester will allow you to look at the freeze frame data stored in the
PCMs memory.
NOTE: If the Erase Codes function was performed, then no freeze frame data will
be stored in the vehicles memory.
To view the freeze frame data, select View
Freeze Data from the OBD II Function Menu.
