Q: Startcenter software cannot be installed correctly on a PC!

A: Prior to installing Startcenter , check if the PC has enough Hard Disk Drive space required for the Startcenter application.
In addition, Virus Scan Software can prevent installation. Prior to installing Startcenter , deactivate all Virus Scan Software for the duration of the installation.

Q: Startcenter cannot communicate to the KTS 340 tester because USB driver is not detected or installed.

A: During Startcenter software installation on the PC, a USB driver necessary to enable KTS 340 communication is also installed. If Startcenter cannot communicate to a KTS 340 after installation, remove and install Startcenter using the “Add/Remove Programs” within Windows and ensure all steps are closely followed.

Q: Startcenter does not indicate that new KTS 340 Diagnostic Application Software updates are available.

A: Startcenter looks for and manages available KTS 340 Diagnostic Application Software updates online.

To accomplish this, an account with the ESI[tronic] server is required so that Startcenter can obtain KTS 340 Diagnostic Application Software updates. The Registration Form which came with the KTS 340 kit should have been completed during purchase and sent to Bosch Customer Service. If this was not done during the purchase, then please fill out the Registration Form and send it to the Bosch customer service in order to set up an account.

Once completed, new Update DVDs will be received via Post Mail. Along with Update DVDs will be Customer Number and Password credentials. This information is necessary to license the device and to download further Online-Updates. Please store this information in a secure location, as future access will be required.

KTS 340 purchase includes free Updates for 12 month with additional vehicle coverage and further enhanced functionality.

Q: When is an Online Update for KTS 340 Diagnostic Application Software available?

A: Startcenter software can be set up to automatically receive Online Updates as soon as they become available. The automatic update feature can be activated in the menu Settings/User Settings under Software-Download. Note that Bosch will also send you an Update DVD for the KTS 340 Diagnostic Application Software via Post Mail.

Q: How to Activate (or Deactivate) the KTS 343 Demonstration feature?

A: Click on the Wrench icon in the upper right hand corner of the screen, select “User Settings”, select “Simulation Mode” by clicking the check box. Once the “User Settings” display is closed, the text “DEMO” will appear in the upper right hand corner of the KTS 340 display.

KTS 340’s across-the-board DEMO feature will allow use of all software functions without a vehicle, so this feature can be used to familiarize KTS 340 diagnostic features (along with other functions as well).

Important! Prior to connecting to a vehicle to perform diagnostics, make sure Simulation Mode is turned off. To accomplish this, click on the Wrench icon in the upper right hand corner of the screen, select “User Settings”, de-select Simulation Mode to remove the “check” by clicking the check box. Once the “User Settings” display is closed, the text “DEMO” will be removed from the upper right hand corner of the KTS 340 display. Diagnostics are now possible.

Q: What is the Diagnosis Socket function used for?

A: The Diagnosis Socket function provides applicable information prior to performing Diagnostics. The function adds helpful information such as the diagnostic data link connector(s) (DLC) location for the vehicle being diagnosed. Pin locations inside the data link connector are also identified. This includes identification of data link communication circuits and their pin locations on each DLC, which are required for pin adaptation on non-standard OBD II applications where a vehicle specific adaptor is available.

Q: How is a vehicle identified within the KTS 340?

A: The KTS 340’s revolutionary vehicle identification feature includes three ways to identify a vehicle:
  1. Automatic ID -> a one-button function which automatically reads the VIN number and decodes VIN to the correct vehicle that is ready for Diagnostics. This is KTS 340’s fastest vehicle identification method.
  2. Manual VIN Entry -> provides a means for the entire VIN to be manually input into the Tester. Once the complete VIN is entered, function automatically decodes the VIN to the correct vehicle that is ready for Diagnostics.

    Note: User input of the entire VIN is necessary as the VIN is automatically stored to the Report when “Save” is clicked.
  3. Manual Vehicle Selection -> allows for a multiple level vehicle selection starting with commonly understood Automotive Technology practices. As an example, the user selects Year, Make, Model, Sub-Model, and so forth.

Q: When is the Automatic ID Feature Supported?

A: Automatic ID feature is supported for most Model Year 2005 and newer vehicles (sold in the United States) from which the Vehicle Identification Number (VIN) can be read through the 16-pin OBD II DLC connector.

Q: KTS 340 cannot communicate with one or more ECUs on the Vehicle.

A: Communication with an ECU in a vehicle requires User setup steps. If problems are encountered, check the following if No Communication, No Data or ECU Response is observed:
  1. Turn Ignition or Run Switch ON
  2. DLC Connection
  3. Tester Hardware Configuration (using correct adapter)
  4. Vehicle Communication Network Performance
  5. +12v Power supply at Pin 16 of the DLC
  6. Good Grounds at Pins 4 & 5 of the DLC

Q: KTS 340 cannot communicate with an Engine ECU.

A: If Communication with the Engine ECU is not achieved despite repeated attempts, the Immobilizer ECU may be blocking the KTS 340 from communicating to the Engine ECU. This may happen if the vehicle has been parked with doors open and Ignition/Run Switch may have been switched on and off, but the engine was not started.

Remedy: Briefly lock and then unlock the vehicle, or activate and then deactivate the immobilizer, and re-attempt tester communications to the Engine ECU.

Q: KTS 340 cannot communicate with one or more ECU(s) due to Aftermarket radio installation.

A: If communication with the Vehicle ECU(s) cannot be achieved despite repeated attempts, check for installation of an Aftermarket Radio. This condition may block the KTS 340 from communicating as the “Aftermarket Radio Installer” could have miss-understood Serial Communication lines as a +12v power source.

Remedy: If the vehicle (e.g. Volkswagen) is fitted with a radio that does not correspond to the original equipment, the diagnosis of various other systems may be affected by this. The problem can be remedied by temporarily removing the radio.

Q: KTS 340 cannot communicate with ECU(s) due to communications on wrong tester adapter pin.

A: If the KTS 340’s manufacturer-specific adapter cable is not used, the User must correctly connect the Tester’s adapter to the Vehicle DLC using suitable jumper cables.

Note: if the wrong pin is connected from the Vehicle DLC to the Tester adapter, communication cannot be established.

Q: KTS 340 cannot communicate with ECU(s) due to use of incorrect tester adapter (e.g. “Diagnosis Plug”).

A: Several Vehicle Brands, Models, or ECU Systems require specific adapters to be used with the KTS 340. Generally this applies to Model Year 1996 “older” vehicles, and also includes some OEMs which used “Dealer” connectors until roughly Model Year 2000.

Note that some of these “non-Standard Dealer” DLCs are mounted at different locations throughout the Vehicle. Consult appropriate Service Information to determine DLC location.

Q: KTS 340 cannot communicate with ECU(s) due to incorrect ECU variant.

A: The vehicle ECU may not the variant type expected by the KTS 340. ECUs from different manufacturers may be fitted in the same Vehicle Model which may require slightly different system selection.

Remedy: the KTS 340 may display more than one ECU system for the Group selected. Because of ECU system variants, ensure that communication to all ECU systems is attempted.

In some instances, a Replacement ECU may be different than Original equipment. Often hard to detect, a check of the ECU part number (outside marking), Calibration ID (use Global OBD II for powertrain ECUs), and if possible, if recently replaced, the ECU Source (e.g. Salvage Yard, Border Country Zone)

Note that Automatic Search is not possible for ECUs which support blink code functionality.

Q: What to do if the KTS 340 will not Power On?

A: A minimum of +12v voltage supply from the vehicle must be present. For example, use of Pin 16 for +12v and Pins 4 & 5 of the 16 pin OBD II DLC is necessary to power the KTS 340.

If either Power or Ground is not available from the DLC, the KTS 340 can be powered using the Auxiliary Power / Cigarette Lighter Port cable, or connection directly to the Vehicle Battery positive and negative posts.

Q: What does it mean if ECU Systems are identified as "Minimum Function"?

A: Since the KTS 340 has “global knowledge” of so many ECU systems it may not fully identify an ECU System however may still allow for “minimum function” diagnostics for that ECU System. Depending on ECU system, Minimum Function may include Identification, Read DTCs, Clear DTCs, and in some cases, reading Diagnostic Data Parameters using SnapList.

Note that future KTS 340 Diagnostic Application Software Updates will add necessary programming to allow for full diagnostics of ECU Systems that fall into this category.
