The following program files must remain in same directory for program to run.

You can only rename the file obd2.exe if desired.

obd2.exe

pid.bin

dtc.bin

test05.bin

test06.bin

obd2.hlp (which is this program)

Readme file

This is a text file containing purpose, installation, status and contact information

README.TXT

Sample scan  files

Included in the zip files are sample scan data

for information on these files see files and folders

scan1.log

obd2.exe will run the program and initial agreements.

No dll files or run time libraries or used.

No settings or made to any operating system files.

No directory folders or made

No program groups or made.

No entries are made in registry or operating system  ini files

The browser software will not become part of operating system.

Removal

Using  file manager delete the above files listed above.

Errors

If any program files are missing you will get a error box message

the scan tool program will exit and a error text file will be made.

It is recommended that you unzip the files again.

Initialization

Each time the scan tool program runs it will load a initialization file of various

user settings.  This file named obd2.ini must remain in same directory as the obd2.exe program.

The initialization file is created on first use with default settings or if the file is missing.

The serial port setting is automatically checked for available ports and a prompt

generated if new initialization file or current port setting is not available.

First Time Use

Connection

1.

Locate a rs232 communication port on your computer.

They are either a male  9 pin or 25 pin.  Most new computers will have

a 9 pin port available.  Old computers will have a 9 pin and 25 pin.

One of the serial ports could be in use by your mouse, if it is a 9 pin

you can either buy a 9 pin to 25 pin adapter or switch ports and

reconfigure your mouse driver port setting.

2.

Plug the 9 pin female rs232 end of the interface shell or cable  into your computer.

Plug the 16 pin male OBD-2 connector into your car.

If needed you can extend the interface shell or cable to computer connection up to 50 feet using

a rs232 cable.


print
Printing

Selections will print the current data contents

of a page.  Printing a form will print

the whole page.


File

New

Will create a new directory folder  on your disk drive.

This is recommended if you have several vehicles or would

like to categorize your scans by other means.  This will

keep the scan tool program files separate for easier maintenance.

Open

Will open scan files.

Each scan will generate the following files:

(where name represents a chosen scan name)

and all will be opened for viewing

log file  "name .log"

comments file   "name .txt"

data file    "name .dat"

vehicle information file  "scan.vin"

scan number file   "scan.num"

The default extension is .log

Save and Save as

Will save current open file or rename and save.

During a scan the data file is continuously saved

in the file data.tmp which is renamed after the scan.

data.tmp is also used as a back-up for data recovery.


Connect

This will initiate a connection with the vehicle.

The key most be fully on too ignition

or the engine running.

The initiation sequence can take several

seconds for the ISO-9141-2 protocol.

The program will continue to try until

canceled by user.

A  ISO-9141-2 vehicle will disconnect after

5 secs. if a message request is not sent.

Avoid  use of  computer operations that

have long routine times during your scan.

All initializations are recorded in the log list box on the "Info" folder page.

If a connection can not be made, you will receive a message box

stating check ignition switch, connection and vehicle OBD-2 network.

To cancel the initiation sequence at any time press the terminate button

located in the middle of the screen.

NOTE: First time users, If you have not entered your user ID, pressing terminate

will then ask for your ID entry.


end
End and Exit

End will disconnect your vehicle connection and end the scan.

You will be asked if you want to save the data.

Exit will perform the same functions as End

and will also ask you if you want to exit program.


Replay

When a file is opened or at the end of a scan.

A data replay control panel is available.

It will play back the data,

Speed can be selected in frames per sec.(fps)

in 5 fps increments from 0-500 fps.

Note this is a set point, depending on your computer you

will probably not be able to obtain 500 fps.

The spin setting is located on far right.

To jump to a specific section use the set spin button.

The units or in percent 0-100 of total messages in 5% increments.

The numerical display is in percent and corresponds to the bar graph.

The spin setting is located on far left.

To end a replay either press end in main menu or the close menu

of the replay form.

You can move the replayer to different parts of screen by holding down

mouse in top section.


Frame-packet
Frame and Data Packet

Frame is defined as one message received from vehicle.

Data packet is all the data items contained in a message.

One frame will contain one data packet consisting of one more data

items that will be seen by scan tool as received at same time.

For SEA J1979 protocol O2 sensor voltage and fuel trim will

be in a packet, and received at the same time.

This should be noted when analyzing response times and correlating

data.

SAE J1979 sends a request to all computers on the network and waits for

any replies before timing out.  It is possible to get multiple responses from different computers,

or multiple replies for trouble codes and mode 06 test data.

If you get messages from different computers you will see a red status message

under the data listing.

When using play back multiple responses will show as a jump in the data point.


Units

The SAEJ1979 specifications has scaling factors

for either SI (Metric) or English.

Temperature is degrees Centigrade or Farenhieght

Fuel Pressure is KiloPascalsGauge or pounds per square inch gauge

(note gauge represents 0 as atmospheric pressure)

Intake manifold absolute pressure is KiloPascalsAbsolute or inches of mercury

(note absolute represents 0 as a absolutely pure vacuum;  vacuum defined as a

absolute pressure below the current atmospheric barometric pressure.)

Vehicle speed  is either kilometers per hour or miles per hour

Air Flow rate  is grams per second or pounds per minute

Trroubleshoot
Trouble shooting

1. Make sure key is fully on or engine is running.

2. You are connected to your computers correct rs232 port.

3. You have entered your user ID for first time connection.

A ISO connection can take several attempts with each

initialization lasting 2.7 sec.  VPW and PWM usually

connect in 0.1 sec.

Check your login listing found on the "Info" page.

You will see rs232  and OBD-2 interface connection listings.

The blue router box interface is used for VPW, PWM and multiple interfaces,

will show route F4 in log file if connection is made to  the unit.  It will then

proceed to verify various route settings until connection is established.

The ISO and indo-3 interfaces do not list route numbers.

In options-gateway main menu you can verify and change router settings and  serial port number

if needed.

If during data logging you are having time outs or disconnects; for ISO connection

increase the speed, byte and message settings.   For VPW and PWM your car will

have multiple computers on line, you will need to increase the timeout setting to 5 or more.

Many Ford vehicles will respond with 3 or more  duplicate messages, make sure delete duplicate messages is checked.

Some Volvo vehicles the transmission controller will respond.  If this not desired select the engine controller or other

address accept filter listing.

Color

This setting is found under the options menu.

You can choose back ground, axis and plot colors.

for the graph, panel meters and gauges.  A sample graph and gauge is

illustrated.

Note: Try to pick different colors for each graph data item, and

the graph axis.  To conserve memory the software recognizes

colors when switching between forward and reverse in play back,

If you change background color all graph data will be erased.

The colors also apply to the O2 sensor graph.

When printing choose a white background to conserve ink.

This is done automatically  for O2 graph.


Gauges

To design gauges you can either click on a gauge or

select "gauge" under options menu then click a gauge to modify.

You can set all possible SAE J1979 gauges listed in list box on left.

Note:  Not all vehicles will support all gauges.

The gauges your car will support is listed under

mode 01 pid 00 supported current data items on the data page.

Currently there are no logic indicator lights.

There are no stop pins on gauges, this will not damage software but

can generate false readings if range is exceeded.

You can have several gauges the same with different ranges.

The gauges or not moveable, you can move the gauge designer form

by holding down the mouse button at top.


network
Gateway

This item is found under the options menu.

Note: These are advanced settings.  Software versions

after  March 2000 are preconfigured based on user ID.

Protocol

The protocol column lists the possible OBD-2 protocols

that can be found on vehicles.

Each protocol corresponds to your interface.  Example if you have a ISO

interface the ISO-9141-2,  and KWP2000 selections will be checked.

For a 3 unit interface all protocols will be selected.

If you will only be using one protocol for specific manufacturer then you can deselect

other protocols if not needed.  This can provide faster connection.

During connection the log listing will indicate the protocol route.

The default setting will select and try all protocols.

The second column lists the SAE J1979 message request time.

This is used to give all computers on the bus time to respond before

sending another request.  The default time out is 100ms for VPW and

PWM, and 55 ms for ISO.  Most cars can handle 50ms (20Hz) for response

from one computer with a single return message which is typical

for mode 01 real time data items.  If you decrease this too much you will get time out

and disconnect messages.

The third column is specific to ISO only, this is a delay time between

each byte in a request.  Most requests consist of 6 bytes.  The

standard time is between 5 and 15 ms. thus a additional 50ms delay.

Most cars work ok at 5ms.  Some Chrysler cars need 10ms to maintain connection.

The fourth column is specific to ISO only, this is a message delay time out to separate

responses.  If you are getting checksum errors in log listing decrease this setting.

Note: this setting will not change data acquisition speed.

Timeouts

Timeouts will attempt to retransmit the request if no response is received.

The SAE default is one.   After the number of timeout requests have expired the browser

will send a Mode 01 Pid 00 request to see if you are still on-line with your vehicle.  If true

then the data you requested is not supported.  If false then you have lost the connection.

If you are experiencing random itime out problems, your vehicle could have multiple computers

Increase this setting to prevent timeout messages for real time data.

Note: not all vehicles will support all requests.  Example Ford does not support Mode 05 O2 sensor test results.

Time outs and no responses will be listed in the log listing.  There is also a timeout indicator light above the

log listing.

Interface

Interface selection box provides selection of interface, this should not be changed unless you obtain

a different interface.

Single applies to the ISO single unit interface and also early single unit versions of VPW and PWM.

Blue route applies to late model single VPW or  PWM and all dual and triple combo boxes.

The blue route selection will also work with single unit interfaces.

Industrial applies only to the indo-3 unit.

Upon connection the log listing will indicate the selected interface.

Serial Port

This applies to your rs232 serial port connection.

Upon each connection the browser will check or attempt to indentify a serial port.

You can manually change if needed by selecting a port number.

You can change baud rate to any listed value.  The baud rate settings higher than 19.2 only apply

to the blue route box when using VPW or PWM routing for boxes manufactured after April 15, 2000

If you are using a blue route box of earlier date you will be unable to connect using the higher settings.

Address filter

The filter table allows you to accept responses from specific vehicle

servers only.  Listed or the assigned network names and addresses.

This can prevent multiple server response to same request.

Most cars currently only use the OBD-2 bus for diagnostics from one

engine controller computer, in response to scan tool only.

GM trucks and some Ford's use the bus for several inter server communications

which this browser currently filters out.  Some Volvo can respond with

messages from engine and transmission.

Clear Cache

This was part of a early version to clear data grids upon reconnection.

Support for this is presently unknown.

Test Device

Mode $3F test device present if checked will send a SAE J2179 physical message every 4 secs. to indicate

the scan tool browser is present.  This was a attempt to prevent real time data timeouts.  It seems to have no

use and is not documented by manufacturers.   It does not apply to ISO interface.

Delete Duplicate Messages

Many Ford PWM vehicles will respond with 3 or more of the same messages.  There is no SAE support for this and

browser errors could be generated.  If this occurs you will see multiple listings of the same data item.

The current browser will delete duplicate messages as initial preconfigured setting if a PWM router is used.

If you uncheck and  do not have duplicate messages or using GM VPW you can increase speed slightly

depending on your personal computer.
