Intended Use

Product Intended Use
Bosch complied with the following regulations specific to the target market when developing the product: USA, Canada.
If other or additional regulations are required for marketing the product or marketing is effected outside the named target markets, the customer requests compliance with the specific regulations of the target market from Bosch, or ensures these by itself.
Provided that iTraMS CCU is used within the conditions (environment, application, installation, loads, antennae) as described in this user manual and the corresponding agreed upon documents, Bosch ensures that the product complies with the agreed properties. Agreements beyond this require the written approval by Bosch. The product is considered fit for the intended use when the product successfully has passed the tests in accordance with the user manual and agreed upon documents.
It is the responsibility of the customer to ensure the proper application of the product in the overall system/vehicle.
Bosch does not assume any responsibility for changes to the environment of the product that deviate from the user man and the agreed upon documents.
If, in order to connect the device, ignition and battery are bridged, the device will draw the full operating current even when switched off. In this case, without any further deactivation on the vehicle-side, there is a risk of battery depletion. No liability is assumed for any damage occurring because of this. There are no specific ventilation openings or heat sinks in CCU device but mounting in a thermal capsuled environment should be avoided, as it will lead to an increase of the operating temperature.

Product Safety

Functional Safety

Bosch points out that the system/product does not implement any ASIL- classified requirements (in the sense of ISO 26262). Therefore, it has not been approved by Bosch for applications in which Bosch delivered system/product has an ASIL related (above QM) role.

   • Definition of following terms: Customer Data, Data Protection Laws, Personal Data, Security Incident
   • Ownership and Use of Customer Data
   • Data Security Breach Notification
   • Audits and Inspection · Security

2. General Information and Limits About Cybersecurity
   The Robert Bosch GmbH (“Bosch”) determines the State-of-the-Art of information security (Cybersecurity) of his products on yearly basis. In case the product does not fulfill the requirements derived from the State-of-theArt of information security any more, Bosch reserves the right to stop shipment of the affected product. Before,
   Bosch will inform the customer as soon as possible and support the customer to fulfill new security requirements.
   In case a security vulnerability is discovered or disclosed to the customer, Bosch should be informed up-front its publication.
   The installation of security relevant updates has to be done by the customer.
   The product or embedded control unit contains engineering access points in hardware and software to execute Bosch services for manufacturing and development investigation purposes, including the capability to perform a software reflash. These Bosch interfaces are secured by:
   • The design of the printed circuit board (PCB)
   • Device individual passwords
   The product does not contain any measures to resist (D)DoS attacks, as there is currently no known effective mechanism within individual E/E components available. If (D)DoS attacks have been evaluated as safety critical, this shall be considered by measures on vehicle level.
   The product is not designed in a way to withstand fault injection or side channel attacks.
   The Software used in the product, contains intellectual property (“IP”) from Bosch, the customer and probably 3th parties. For the purpose of IP protection and to avoid re-engineering, the Software shall be handled as confidential during the distribution process into plants, workshops and FOTA. This shall be considered by measures within the Customer’s Software Logistic Infrastructure and involved processes.

3. Cybersecurity Assumptions
   Information security measures can be implemented differently in the vehicle and its environment (security layers). Therefore, Bosch presumes that the customer satisfies the following assumptions by his security design of the overall system.
   Integrity
   • The by the customer or 3rd parties designed or implemented interfaces do not offer any service or routine to alter the memory content, besides the regular Software Update (Reflash) services.
   • The by the customer or 3rd parties designed or implemented interfaces which are offering services to change executable memory content, are well secured and limited to engineering purposes (e.g. XCP).
   Confidentiality
   • The by the customer or 3rd parties designed or implemented interfaces do not offer any service or routines to readout data from Bosch or 3rd parties.
   Availability
   • The by the customer or 3rd parties designed or implemented software does not compromise the intended code execution or system availability of the product.
   • Only, secured (signed) Software Updates (Reflash) are possible and no unsecure software update mechanism is implemented by the customer or 3rd parties.
   • Bosch presumes that the customer takes care of a secure in-vehicle communication by implementing measures beyond the scope of the product or system to preserve the authenticity and freshness of the relevant signals, that are essential for the functionality of the product or system that contribute to vehicle automation features, at any time during operation.

Safety and Warning Notes
Read this document carefully. The information applies to the devices described in this manual. Save this manual: it contains important safety information and operating instructions.

• Always observe all standard and accepted safety precautions and guidelines when handling any electrical device.
• Only trained and qualified personnel may work on the vehicle.
• Always follow the specifications and instructions of the vehicle manufacturer.
• Do not attempt to disassemble the product: Doing so will void the warranty.
• Opening or trying to open can lead to damage or malfunctions of the CCU or components connected to it.
• Your workplace has to be dry, as well as sufficiently lit and ventilated. Do not smoke in the workplace.
• The device must not come into contact with hot or burning objects (e.g. cigarettes).
• Do not insert foreign bodies in the insertion slots or openings of the device ­ otherwise injury or damage to the device may occur.
• RF exposure. Keep at least 20 cm (8 inches) separation distance from the controller and the human body.
• Check the electrical lines to make sure they are properly insulated and fastened.
• Wear suitable protective clothing, as the situation requires.
• Bosch assumes no responsibility for damage as a result of incorrect indicators/displays. These may arise if the device has not been connected or has been incorrectly connected or if the device receives false or erroneous signals from the system.
• Formation of condensation on the device must be avoided. In case of condensation formation, you must allow an acclimatization time of up to two hours to ass.
• Ensure enough ventilation around the device otherwise a build-up of heat may occur in the device that could lead to malfunction.
• It is to be ensured that there is no water ingress into the CCU with the right installation and packaging inside the vehicle.
• The product’s operating safety is only ensured if the permissible conditions are maintained
• The CCU operation is permitted only with the software and configuration data verified and released for the respective project. A change in the software, configuration data of the CCU, or in other control units in the vehicle network, or the change of components can lead to malfunctions resulting in possible damage to components or non-conformance to the legal requirements, or can lead to hazards.
• The connection of the CCU to vehicles or engines, which do not correspond to the validated configuration, can lead to damage or malfunction of the CCU or connected components. E.g., this can occur if different types of control units having identical electrical connectors are used.
• For a secure connection, the interlocking mechanism of the connector must not be damaged and must be in a completely closed state.
• It must be ensured that the connector from the wiring harness side is disconnected only in dry and clean conditions
• A connection / disconnection of the control unit to / from the positive / negative terminals of the battery when ignition (T15) is switched on (closed main relay) can lead to malfunction or errors in diagnostics and is therefore prohibited.
• Depending on the software used, for a complete functional capability of the CCU after “ignition off” (T15-OFF) the supply voltage to the CCU must be maintained via the main relay (e.g. for storing the functional parameters, conducting diagnosis tests, writing of the error memory etc.).
• Hint regarding the eMMC (Flash): The periodic or repetitive saving of important characteristic data (diagnostics results, error memory etc.) takes place in an eMMC. The maximum number of write cycles of this memory is limited and is also dependent on the ambient conditions, especially the temperature. Frequent overwriting can lead to defects, data loss and function errors. The customer is responsible for the compliance with the limit values if he creates the software.
• The life time of eMMC depends on RW/WR cycles used in application, discussed and agreed between BOSCH and customer.
• External antenna selection compatibility should be agreed between BOSCH and customer
• The instructions in this document and the instructions relative to the wiring harness must be followed.
• The number of mating cycles (10) of the plug connection and antenna connection between control unit and wiring harness plug is limited. Repeated connection and disconnection can lead to contact degradation and subsequent malfunctions and/or trigger diagnostic errors.
• The number of mating cycles can be found in the technical specification of male and female (wiring harness side) connector.
• If the unpacked control unit falls on a hard surface, such as a concrete floor, it is NOT ALLOWED to use the control unit because non-detectable damages can affect functions and the reliability.
• The mounting of the CCU in the vehicle should be selected such that the conditions described in this manual and the associated documents are adhered to. Specifically damage could result from excessive temperature, vibration loads or the effect of specific substances. Customer to inform Bosch the mounting location of the CCU with pictures, this is very critical for Bosch to validate the mounting, if required Bosch will visit and assess the mounting location on site.
• Suitable protective measures against electrostatic discharges are to be taken for persons and tools. In particular, CCU connector pins are not supposed to be touched.
