Baum Tools Unlimited. Chapter 4 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.
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.
Baum Tools Unlimited. c. 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.
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.
Baum Tools Unlimited. Chapter 4 C. DTC Help tips a. Help tips are provided when you press the [HELP] key after locating the highlighted bar on one of the detected trouble code(s). This function is available when DS2020/2021 detects one or more trouble code(s) b. Help tips including trouble code definition, conditions and check points are provided for all Korean cars and Malaysian cars as of May 2003. Wiring diagrams are also provided for Korean cars of 2000 model-year or older. c.
For DS2020/2021 USER MANUAL 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.
Baum Tools Unlimited. Chapter 4 C. Data Freeze The [Data Freeze] function places the selected data stream variable on top of the LCD screen so that the user can check and compare desired sensor values continually without having to scroll up and down. This is different from ‘Freeze Frame Data’ function of Generic OBD2. 1) Step One Select a desired sensor using the [◀][▶] and the [▲][▼] keys. 2) Step Two Press the [ENTER] key to freeze the selected sensor. i.e.

Baum Tools Unlimited. Chapter 4 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.
USER MANUAL For DS2020/2021 IV. Black Box -------------------------------------(= Record Replay) Just like the 'Black Box' or a ‘flight recorder’ of an aircraft, DS2020/2021 can 'record' data stream during the vehicle drive test and the recorded data can be 'retrieved' later for intensive analysis of vehicle's condition.

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.
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.
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.
USER MANUAL For DS2020/2021 much different from OBD generation 1 but only the appearance of diagnostic adapter. This is so called MOBD or manufacturer’s OBD. c. With DS2020/2021, MOBD communication is supported for all car makes that are included in the coverage list.

Type B: Both of the high tension codes are exposed(ILL. 4-27), but the primary side lines are not available.
Baum Tools Unlimited Page 63 DS2020 User’s Guide ILL.4-27. DLI Double Ended Coil - Secondary Trigger d. For Type B, you can select the secondary trigger itself as shown in ILL. 4-27. Connect the clamp to one of the negative high tension cables(CH3). Attach the probe without needle to the other positive cable (CH2). e. For Type C, a stable pattern display can not be obtained. Just connect the probe without needle to the high tension cable (CH2).

ILL.4-28. Primary Pattern : DLI Double Ended Coil 3) Secondary Pattern a. If the Secondary Trigger is selected, DS202 will display the Secondary Pattern without displaying the Primary Pattern. When you use the Primary Trigger, DS2020 displays the Primary Trigger first. It is necessary to choose [1.
Baum Tools Unlimited Page 65 DS2020 User’s Guide 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.
Baum Tools Unlimited 4) Page 66 DS2020 User’s Guide Display Control Functions a. NEGATIVE / POSITIVE Selects the discharge polarity of spark ignition ○ When the selected polarity differs from vehicle's actual discharge polarity: the waveform may be displayed upside down or the waveform may not be displayed at all The polarity switches between Positive and Negative when the [5] key is pressed b. All other functions do the same as previously explained. Refer to the distributor vehicle part. 5.
