This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates, uses,
and can radiate radio frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference in which case the user will be required to correct the
interference at his own expense.
Using This Cartridge With A Tech 1 Or Tech 1A Tester
The TECH 1A tester is an updated version of the TECH 1 tester. In addition to already proven TECH 1
diagnostic power, the TECH 1A has on-board RS232, Instrumentation Port, and DC Power Jack
capabilities. You can identify a TECH 1A by the phone-style jacks on both sides of the tester.
Note that the TECH 1 and TECH 1A require a different DLC cable, DC Power cable, and vehicle adapters.
When using this manual to diagnose a vehicle, take the time to determine the type of tester that you have,
and be sure you are using the correct cables and adapters. Doing so may prevent misuse of application
cartridges and incorrect vehicle diagnosis.
The hardware required to connect a Tech 1A tester is described in Chapter 2 of the application manuals that
follow.
On some vehicles power to the cigarette lighter is controlled by the ignition switch. When testing these
vehicles with a TECH 1 or TECH 1A, it is best to connect the tester directly to the battery with the optional
Battery Adapter Cable (P/N 02001636), which is available from your TECH 1A distributor.

•Engine Control Module ECM (OBD II)
•Engine Control Module ECM (OBD I)
•Body Control Module BCM
•Anti Lock Brake/Airbag ABS/AIRBAG
When diagnosing a specific Suzuki system, be sure to reference the correct system application section in
this manual.
The SUZUKI ECM (OBD II) Application is used to diagnose and troubleshoot the Engine and Emission
Control systems used on 1996 and later Suzuki vehicles. It takes full advantage of advanced diagnostic
features introduced in these vehicles.
The SUZUKI ECM (OBD II) Application and the Vetronix tester team up to become a diagnostic tool which
is both powerful and easy to use. With the Vetronix tester, you can select test modes which let you:
•Read engine data parameters.
•Diagnose intermittent problems by capturing and storing multiple samples of system data BEFORE AND
AFTER THE PROBLEM OCCURS, then examining the data to determine the problem. This data is
saved in the tester memory for at least 24 hours even if the power is removed from the tester!
•Control engine functions such as RPM (except CARB mode).
•Control various solenoids, and valves on or off to check for proper operation (except CARB mode).
•Read ECM configuration information (SUZUKI mode only).
•Print data and vehicle information.
•Read A/T data parameters (vehicle equipped with PCM).
The Suzuki ECM (OBD II) Application is capable of monitoring and diagnosing the Suzuki engine and
emission control systems on all models equipped as follows:
The CARB (California Air Resources Board) Mode of operation provides standardized testing of emission
related components.
A further description of the CARB Mode and instructions for operating the CARB Mode test procedures are
included in Chapter 6.

MODE F1: PRINT DATA
PRINT DATA
When the RS232C I/F Cartridge is installed in the TECH 1, or if you are using a TECH 1 Series A tester, the
Print Data mode allows you to print the VIN, engine type and Data List to a serial printer or terminal. This is
the data list sent by the engine computer to the tester. The data list parameters can be printed without
printing the VIN or engine type by pressing the * key in the Data List or Snapshot Replay mode.
To operate the Print Data mode, do the following:
1. Press ! to select the Print Data mode from the Select Mode menu. The VIN entry screen is the first
screen displayed in this mode. Only the last 6 digits of the VIN are entered on this screen. This
information is then printed out as part of the header information that accompanies each data list print out.
The VIN is entered via the numeric portion of the key pad and the e key is pressed to move to
the next section of the print function.
2. The next screen requires the e key to be pressed to start printing the data. This screen allows the
cable to be connected between the RS232C Cartridge and the receiving device.
3. When the e key is pressed the “WAITING TO PRINT DATA” screen is displayed until printing
begins. If this screen is displayed for more than a few seconds, something is wrong with the set up.
Check that all connections are secure, and that any receiving device is turned on and in the proper
receive mode.
4. As printing begins, the tester displays the % COMPLETE of th e prin t pro cedure. After the printing is
100% complete, the VIN screen is immediately displayed with the previously selected VIN. Pressing the
e key twice from this screen will cause another data stream to be buffered for printing as soon as
the current data stream is output from the tester.
5. Pressing the x key at any point will cause the select mode menu to be displayed. If the x key
is pressed before printing is completed, only the data that has already been sent to the RS232C Cartridge
will be printed. SOME DATA WILL BE LOST.

MODE F3: SNAPSHOT
The purpose of the SNAPSHOT test mode is to help you isolate an intermittent or transient problem by
STORING ENGINE DATA PARAMETERS BEFORE AND/OR AFTER THE PROBLEM OCCURS.
When the tester is operating in SNAPSHOT mode, it is constantly storing information about data
parameters. A time and position index for the stored information is also saved.
The tester stores all of the Data List parameters for the vehicle selected. When the memory is full, the oldest
(earliest) data collected is erased to make room for new information.
A “TRIGGER” tells the tester which data to save. While operating the SNAPSHOT mode, you can always
cause the trigger to be set by pressing e. Once the trigger occurs, the tester saves the data for review.
VIEWING CAPTURED DATA
By selecting F3: REPLAY DATA from the SNAPSHOT menu you have the option of bypassing the Data
Capture phase and displaying previously captured data. All data captured during SNAPSHOT will be

8. FINISHING UP
After using the SUZUKI Application Cartridge, a few simple steps will insure that you get the most life out
of your diagnostic tool.
First, remove power to the tester by disconnecting the serial data link cable from the serial data link
connector. You may want to inspect the cable and connector for any damage or corrosion.
Next, unplug the cartridge and store it and the cable in the travelling case.
If the tester should become dirty you may wipe it off with a clean cloth and mild detergent or hand soap.
Avoid using harsh solvents such as petroleum based cleaning agents, Benzene, Trichloroethylene, etc.
Although the tester is water resistant, it is not waterproof so be sure to thoroughly dry off the tester prior to
storage.

TESTER STOPS COMMUNICATING WITH
THE VEHICLE
LOSS OF VEHICLE
COMMUNICATIONS
Possible Causes
•Vehicle's ignition was turned off.
•Diagnostic cable came loose from vehicle's diagnostic connector.
•Vehicle failed to respond to query from tester.
Recommendations
•Verify vehicle's ignition is on.
•Verify cable is plugged into vehicle's diagnostic connector.
•Turn tester and vehicle's ignition off. Then turn ignition to on, followed by turning on the tester and
attempting to reestablish communications.
•Some vehicle's fail to respond properly to tester queries for certain tests. This is particularly true with
oxygen sensor tests if all Readiness Tests have not been completed. If possible, drive the vehicle to
complete the Readiness Tests and then rerun the tests.
PARAMETER UPDATE RATE IS SLOW
Probable Cause:
•A slow update rate is characteristic of OBD II communications. A typical update rate is approximately
125 to 150 ms per parameter (7 or 8 updates per second for a single parameter). Therefore, a typical list
of 20 parameters will only be updated approximately every 3 seconds.
Recommendations
•If a faster update rate is needed, select fewer parameters using the SEL USER DATA function. Select
only the parameters needed for a test. For example, you can look at just an oxygen sensor signal and get
an update of 7 or 8 times a second.
Suzuki Aftermarket ApplicationPage 78
Page 93
9. If You're Having A ProblemECM (OBD II) Application
NOT ALL PARAMETERS ARE DISPLAYED
Probable Cause
•The vehicle is not reporting all of the parameters. The CARB MODE queries the vehicle's ECM to
determine what parameters are supported by the ECM. The tester then creates a Data List based on these
parameters. If the vehicle contains a particular sensor but does not tell the tester that it supports that
parameter (e.g. a downstream oxygen sensor) the tester will not display that parameter.
•A custom parameter list was defined in the Select User Data mode.
Recommendations
•Diagnosis must be performed based on other diagnostic data or procedures.

A. UNDERSTANDING SUZUKI
ECMS
The serial data link uses message-oriented transmissions with a UART type data format. The communication
is via a single-wire half-duplex bus using a master/slave protocol. The serial data link can be used for
communications during normal operation or as an interface to a test device for diagnostic operations. If there
is no requirement for data sharing between the vehicle's components during normal operation, the link can be
implemented as a diagnostics only link. Numerous diagnostic modes provide a maximum of system
flexibility.
Interface to the serial data link can be implemented using standard UART type devices communicating at a
10.4k baud rate. The interface devices required for this phase are available as stand-alone devices or
integrated with CPUs (or MPUs) in a large number of micro-controllers.
Network access is via a master/slave protocol. The serial data link can have at most one device functioning
as the master at any point in time. The tester controls all communications on the serial data link. A slave
device (ECM) can transmit data only after it has been interrogated by the master device. A typical operating
scenario is for the master device to periodically send a polling message to one or more of the slave devices.
The slaves can then send a response message (containing, for example, the states of the slave's inputs or
internal parameters) back to the master.
Once the tester has control of the serial data link, it can perform diagnostics on any of the devices connected
to serial data link which support serial data diagnostics. It is important to note that the tester can only
perform diagnostics which were provided for in the design of the various components. Some components
might implement minimum diagnostics such as trouble code and diagnostic parameter readout. Other
components might implement high-end diagnostics including provision for extensive control over the
operation of the component and override of internal parameters. This can be used to exercise specific circuits
in order to assist in the isolation of faults.

1. SUZUKI ECM APPLICATION
DESCRIPTION
The Suzuki ECM Application is used with the tester to diagnose and troubleshoot the engine systems
controlled by the Engine Control Module (ECM) and the Engine and Automatic Transmission systems
controlled by Powertrain Control Module (PCM) that are used on Suzuki vehicles (except OBD II vehicles
that are for the North American market from 1996 to present).
The Suzuki ECM Application and the tester team up to become a diagnostic tool which is both powerful and
easy to use. With the Vetronix tester, you can select test modes which let you:
•read engine data parameters
•read diagnostic trouble codes
•clear diagnostic trouble codes
•diagnose intermittent problems by capturing and storing multiple samples of system data before and after
the problem occurs, then examining the data to determine the problem. This data is saved in the tester
memory for at least 24 hours even if the power is removed from the tester!
•control some actuators
•fix spark advance
•fix Idle Air Control Calibration (IAC CAL)
•print data and vehicle information
This information can be analyzed and displayed to assist service technicians in diagnosing engine and
driveability problems.
The Suzuki ECM Application is included in the Suzuki Application Cartridge. When used with the tester, it
is capable of monitoring and diagnosing the engine with ECM or engine/AT with PCM on the models listed
in the chart on the following page.
