II. SAFETY PRECAUTIONS ----------------------DANGER
When an engine is running, keep the workshop area WELL
VENTILATED or attach a building exhaust removal system to the
engine exhaust system. Engines produce carbon monoxide, an
odorless and poisonous gas that causes slower reaction time
and may lead to serious injury or death.
WARNING
Brakes and wheel blocks
Apply the hand brake and block the wheels before using the test
equipment. It is highly recommended to block the wheels on
front-wheel drive vehicles because the hand brake does not hold
the driving wheels.

Do not drive the vehicle and operate the test equipment at the
same time. Any distraction may cause an accident. Have one
person operate the test equipment while the other person drives
the vehicle.
Never place the test equipment in front of you when driving the vehicle because the

DS2020/2021 Functions
The functions you can choose when all the test vehicle details are selected
properly are explained in this chapter of the manual.
The actual list of
available functions may be different according to the vehicle you want to test.
I.
Diagnostic Trouble Code---------------------
A. DTC Read
1. Pulse signal type
a. Many of old Toyota, Honda, Mazda, Hyundai and Kia cars until early 90’s
support slow pulse signal output for the DTC reading function.
As shown below, DS2021 shows the pulse signal being received
through the DLC adapter in the top and the received DTC numbers.
b. Manual input
-
Even older cars such as Honda with 2-pin adapter have no signal
output terminal for DTC in the DLC adapter.
In this case,
DS2020/2021 shows the following message as there is no signal
input through the adapter.
Chapter 4 - 1
USER MANUAL
-
For DS2020/2021
You have to count the MIL flashing on the dashboard and manually
input the DTC number to DS2020/2021 to view the details as
below:
-
Long flash signals count for tens and short signals for ones. Input
two digits for tens and ones in sequence using the numeric keypad.
A flash signal for a code is followed by another if there are multiple
trouble codes.
Blinking signals for all trouble codes flash in
sequence, and repeat after a pause.

Chapter 4
Others
-
Generally DS2020/2021 reads DTC pulse signal from the
diagnostic adapter and shows the DTC number, title and details
automatically.
2. Serial Communication type
a. Most of the cars built in 1990’s or later support serial communication with
a scanner, and the DTC is read by bi-directional communication.
b. DS2020/2021 sends a command to the control module to reply with
the DTC numbers stored in memory, and the control module replies
thereupon.
Chapter 4 - 3
For DS2020/2021
USER MANUAL
B. DTC Erase (Clear fault code)
1. Pulse signal type
a. Pulse signal type does not support bi-directional serial communication,
therefore, a scanner is unable to send a command to the control module
to erase the DTC information from memory.
These old cars require you to remove battery terminal to clean up
diagnostic information from control module memory.
Removing the battery terminal will get rid of all information contained in
the car stereo and other electronic devices. And it may not effectively
erase the fault codes in some cars. Refer to the original repair manual
for further information.
Check if DTC information is properly removed by reading the trouble
code again after erasing the code.
2. Serial communication type
a. DS2020/2021 sends a command to the control module to erase DTC
information stored in memory, and the control module replies thereupon.

Current Data -----------------------------------
II.
(= Data Stream, Live Data, Service Data)
A. Pulse Signal Type
a.
Data stream is not generally supported for this type of old cars because the
speed of pulse signal communication is too slow to read the data stream
variables.
b.
Some of old Toyota cars using 17-pin rectangular adapter exceptionally
support data readings as the system supports relatively high speed pulse
signal communication.
B. Serial Communication Type
a.
Most of control systems with serial communication support data stream
function. Select [Current data] from the menu, then the data readings follow.
b.
Some systems like SRS or ABS may be designed not to support data stream
on purpose by the car manufacturer while the other systems are supported.
A scanner is a passive tool that reads information from the control system,
and it is unable to actively generate information that the system does not
provide.
c.
Some old OBD1 generation Korean and European cars equipped with Bosch
control system that communicates in ISO9141 protocol provide relatively
slower communication speed. Data sampling may seem slow with these
cars

III. Actuation Test ---------------------------------
The actuation test is a very helpful function that temporarily activates
or stops a certain actuator such as an injector, a motor or a solenoid
by force, so that the user can evaluate the system's condition or the
part’s normal operation by observing its reaction
-
Signals from various sensors are input to a control unit, and the
actions are taken by controlling to actuators.
Sensors and
actuators are causes and effects in a control system.
-
While the data stream function is useful to observe if the sensors are
working properly and the control unit is collecting correct data from
the sensors without problem, the actuator test is helpful to examine if
the actuators are working in normal conditions and the control unit is
commanding proper control over the system.
-
Some of the cars such as Nissan or Toyota provide even more
advanced actuation tests by letting the user observe the reaction of
overall control system when manually adjusting the sensor input
values.

while engine is idling, and it will make engine stall or unstable.
c
Testing a fan or an injector is easy to check the proper reaction as it
generates distinctive changes in vehicle condition such as fan whining or
unstable idling. However, valves or motors are generally tested while
engine is stopped and all you can hear may be a small and unclear
electric buzzing sound. Test in a quite place and observe the test
results carefully.

Generic OBD2
I.
Literal definition of OBD and OBD2------OBD is an abbreviation for On Board Diagnostics. OBD-1 is in reference to
Title 13 California Code 1968 titled "Malfunction and Diagnostic System for
1988 and Subsequent Model Year Passenger Cars, Light-Duty Trucks, and
Medium-Duty Vehicles with Three-Way Catalyst Systems and Feedback
Control." filed on 11-15-85. This required cars sold in California to have an
on-board computer processor for on-board self-diagnostics of computer
sensed emission related components, fuel metering device and EGR
(exhaust gas recalculation system). A partial or total malfunction that
exceeded exhaust emission standard would illuminate a MIL (malfunction
indicator light) and provide on-board identification of the malfunction
location. To provide malfunction location information, codes are stored in onboard computer memory. To read codes manufactures use methods, such
as flashing MIL light or various serial data protocols.
OBD-2 is in reference to Title 13 California Code 1968.1 titled "Malfunction
and Diagnostic System Requirements-1994 and Subsequent Model-Year
Passenger Cars, Light-Duty Trucks, and Medium-Duty Vehicles and
Engines. Filed on 8-27-90 to Air Resouce Board (ARB)
This requires a standard electrical connector, open source standardized
diagnostic trouble codes (DTC), data, and communication protocol with more
specific self-diagnostic on-board monitoring of emission malfunctions.

For DS2020/2021
USER MANUAL
II. More practical notes -------------------------A. Technical meaning of OBD2
1. Standardization
a
For the technicians and scan tool engineers, OBD2 has its technical
meaning as bringing the standardized methods of vehicle diagnosis to
the chaotic aftermarket where dozens of car make use different
diagnostic adapters and communication protocols of their own.
b
The 16-pin trapezoid diagnostic adapter and a few of most influential
communication protocols including ISO9141-2, KWP2000, and SAE
J1850 VPW and PWM form the standard OBD2 specifications.
c
Trouble codes and Data stream variables were also standardized and
opened to public, so that all the scanners that support aforementioned
standard communication protocols through the 16-pin OBD2 adapter can
always get the same readouts.
2. Purpose of OBD and OBD2
a. OBD and OBD2 are the names of regulation that were legislated in USA
for the emission control.
b. On board diagnostics was implemented to monitor malfunction or failure
of the emission related parts and components to minimize the possibility
of excessive exhaust gas emission by letting the driver know that the car
has a problem and the technician immediately perceive what is the
problem when any trouble is detected in the emission control system.
And OBD2 became effective later to increase the efficiency of OBD by
standardization.
Chapter 5 - 2
Baum Tool Unlimited
Chapter 5
B. Generic OBD2 and Enhanced OBD2
1. Generic OBD2
a. OBD2 was implemented for the emission control. Therefore, the
standardization is limited to powertrain system that is directly related to
emission control. It is not mandatory for the other systems such as ABS
and SRS
b. Not all the trouble codes and data stream variables are standardized,
also. A list of trouble codes and data stream variables that are closely
related to emission control are defined as OBD2 standards, however, it
also allows more codes and variables reserved for car make’s own
definition and usage. These standardized parts of trouble codes and
data stream variables are so called Generic OBD2. Generic OBD2
application is limited to emission related systems and so is the diagnostic
readouts
2. Enhanced OBD2
a. Generic OBD2 has limited availability for overall diagnosis, however, an
actual car has a lot more than this. The control systems other than
powertrain are not included in the mandatory OBD2 regulations, and
each car make has different trouble code and data stream definitions for
the reserved non-standard fields of powertrain system.
b. The scope of on board diagnostic system that OBD2 standard features
do not cover is called Enhanced OBD2.
3. Manufacturer’s OBD
a. Many of Non-USA cars of 1996 model-year or later have an OBD2 16Pin
adapter, however the communication with scanners does not follow
standardized OBD2 protocols.
b. These car makes maintain their own communication features that are not

LCD screen problems
The display is too dim or too dark
Adjust the contrast using the contrast
wheel on the right side of Scanner
LCD stands for Liquid Crystal Display, and it is very sensitive to
temperature.
If you have placed Scanner in a cold or hot place, the display may
become too dim or too dark when turned on. This is not a defect of
Scanner itself, but a normal response of all LCD’s to the change of
temperature.
This is not a defect of Scanner.
However, if you cannot control the contrast using the dial, please
contact us for further assistance.
A part of LCD became very dark
Adjust the contrast using the contrast
wheel on the right side of Scanner
The LCD unit of Scanner has a backlight for brighter display. This
backlight generates heat as time elapses when turned on.
As mentioned above, because LCD is sensitive to temperature, the
part of the LCD near the backlight may turn dark when you keep DCN
turned on for more than 2 hours.
This is not a defect of Scanner.
However, if the LCD becomes dark too early or the contrast adjustment
doesn’t work, please contact us for further assistance.

User’s Guide
The Duty Cycle function can be used for the rectangular type signals.
In example, Duty Cycle is especially useful for checking the performance of
Idle Speed Control motors, especially for the duty-control type vehicles as
opposed to frequency or voltage control type. The engine load increases when
accessories such as air conditioner, power steering or other power consuming
items are running. The ISC motor therefore increases its active time to increase
the engine RPM for compensation. The Duty Cycle module of DS2020
enables the user to check this performance of ISC motor.

A. What is an Ignition Pattern?
An Ignition Waveform is a graphical representation of voltage fluctuations in a
Page 37
Baum Tools Unlimited
Page 38
DS2020
User’s Guide
recurring procedure - the high voltage from the secondary ignition coil which is
created when the electric power in the primary coil that was fully charged by power
TR collapses when the power TR is turned off. This produces a spark over the
gap of the spark plug in the cylinder, which is used for combustion of the air-fuel
mixture.
DS2020 can analyze both Primary and Secondary Ignition Waveforms.
B. Purpose of Ignition Pattern Analysis
The Ignition Waveform Analysis function of the DS2020 is to provide
an accurate visual representation of ignition waveforms to enable the user to
analyze the possible causes of problems within the ignition system.
By designating X(horizontal) axis for time and Y(vertical) axis for voltage, the
change of voltage in relation to elapsed time during the spark-ignition sequence
can be graphed as a waveform. Waveforms have typical characteristics of height
and duration that can be influenced by various factors.
Since each of these factors brings about a noticeable change in the ignition
waveform, the cause of a malfunction can be traced by analyzing the transformed
waveform in reverse.
C. Basic Supplies for Ignition Waveform Analysis

You will find the inscription 'This side to the spark plug' on one side of the
clamp. Connect the clamp to the spark plug cable of cylinder #1 so that the
inscribed side faces the #1 cylinder spark plug. The spark plug that is nearest
to the generator is usually the #1 plug.
When the clamp is connected properly and the clamp picks up the trigger well,
then DS2020 will indicate it by flickering the ground mark (▼) on screen.
When the clamp is not connected properly, a waveform may still be displayed but
without or incorrect cylinder numbers. In case the high tension cable is not
available or the #1 cylinder doesn't ignite, the clamp should be connected to the
spark plug cable of the other cylinder. The ignition order will then be determined.
DS2020 recognizes the cylinder to which the trigger pickup clamp is
connected to be Cylinder #1. The ignition order of 4-cylinder engines is usually 13-4-2. For example, if the clamp is connected to cylinder #3, the ignition waveform
will be displayed in a row as 3-4-2-1 while DS2020 still displays the

NOTICE
If the clamp is not properly connected, a waveform will still be displayed but
without cylinder numbers. If the spark plug cable is not available or the #1
cylinder doesn't ignite, the clamp should be connected to a spark plug cable
from another cylinder. The firing order will then be determined.
The firing order of 4-cylinder engine is usually 1-3-4-2. For example, when
the clamp is connected to #3 cylinder, the ignition waveform will be displayed in
a row as 3-4-2-1. Similarly, when connected to #2 cylinder, the order will be 21-3-4 and when connected to #4 cylinder, the order will be 4-2-1-3.

C. Trigger Selection
1)
The probe that receives the trigger signal can be selected.
2)
This trigger selection method has been designed to obtain better secondary
ignition patterns of Distributorless vehicles(DLI). On some DLI cars, the
primary lines may be difficult to find.
3)
Since it is very easy to find the primary lines for conventional cars with
distributor type ignition, we strongly recommend that the 'Primary signal' is
selected as the trigger. The secondary signal is not stable enough since it
fluctuates in relation to engine RPM and engine load. In this case,
DS2020 may fail in displaying the correct voltage lines.
4)
To use the primary signal as the trigger, connect the scope probe with needle
to the primary side negative line of ignition coil and the other end to CH1 port
of DS2020 (these cable connections are always recommended for all
cars with distributor ignition)

NOTICE
It is easy and simple to use the secondary signal as trigger - just connect
the probe without needle to a high tension cord. That is all.
However, since the secondary signal is easily affected by engine RPM
and engine load, the resulting waveform may be incorrect and unstable.
Therefore, it is always recommended to use the Primary signal as a trigger.
Despite all the reasons for use of primary ignition signal, sometimes it is
necessary to use the secondary trigger signal when the primary lines cannot
be found. Sometimes the lines of some DLI cars are hidden under metal
shields and plates or may be too short for proper attachment of the probe.

ILL.4-30. Secondary Pattern - DLI Double Ended Coil
As shown in the illustration, DS2020 displays two waveforms. This is
because an ignition Coil of this type discharges both positive and negative
electricity simultaneously to two spark plugs.
For 4-cylinder engines, there are two ignition coils and each coil is connected
to two spark plugs. When one of the coils discharges positive electricity for
example to cylinder #1, it also discharges negative electricity to cylinder #4
simultaneously. When the other coil discharges positive electricity to cylinder #3,
it also discharges negative electricity to cylinder #2 simultaneously.
Therefore, there will be positive discharges in cylinder #1 and #4, and negative
discharges in cylinder #3 and #2 at the same time. Will this cause cylinder #1
and #4 to fire together? No. When one cylinder is in combustion stroke, the
other will be either in the exhaust, intake or compression stroke. Since the
mixture in the other cylinders is not dense enough to properly combust, it burns
but does not fully combust.
From the two cylinders that ignite together, the waveform of the valid electricity
discharge that creates combustion is called 'True Waveform', and the other that
ignites but does not fully combust is called 'Waste Waveform'.
The density of mixtures in the cylinders that are in the strokes other than
combustion stroke are below combustible level. The higher the resistance level,
the higher the voltage is required to bridge the ignition gap. This means that the
peak voltage of the TRUE waveform is higher than that of the WASTE waveform.
Between the two waveforms, TRUE waveform can be distinguished from the
WASTE form in this manner. In ILL. 43, the second waveform is TRUE.
