ANNEX VII In-vehicle system self-test 1. Requirements 1.1. The following requirements apply to vehicles with eCall in-vehicle system installed, STUs and (optionally for) components. 1.2. Performance requirements 1.2.1. The eCall system shall carry out a self-test at each system power-up. 1.2.2. The self-test function shall monitor at least the technical items listed in the Table. 1.2.3. A warning in form of either a visual tell-tale or a warning message in a common space shall be provided in case a failure is detected by the self-test function. 1.2.3.1. It shall remain activated while the failure is present. 1.2.3.2. It may be cancelled temporarily, but shall be repeated whenever the ignition or vehicle master control switch is being activated. 1.3. Documentation requirements 1.3.1. The manufacturer shall provide the type-approval authorities with documentation in accordance with the Table, which shall contain for each item the technical principle applied to monitor the item. Table Template of information for self-test function Item Technical principle applied for monitoring eCall ECU is in working order (e.g. no internal hardware failure, processor/memory is ready, logic function in expected default state) External mobile network antenna is connected Mobile network communication device is in working order (no internal hardware failure, responsive) External GNSS antenna is connected GNSS receiver is in working order (no internal hardware failure, output within expected range) Crash control unit is connected No communication failures (bus connection failures) of relevant components in this table SIM is present (this item only applies if a removable SIM is used) Power source is connected Power source has sufficient charge (threshold at the discretion of the manufacturer) 2. Test procedure 2.1. Self-test function verification test 2.1.1. The following test shall be performed on the vehicle with an eCall in-vehicle system installed in accordance with Article 4, on the STU in accordance with Article 6 or (optionally for) the component, that is made part of a complete system for the purpose of the test, in accordance with Article 5. 2.1.2. Simulate a malfunction of the eCall system by introducing a critical failure in one or more of the items monitored by the self-test function according to the technical documentation provided by the manufacturer. The item(s) shall be selected at the discretion of the type-approval authority. 2.1.3. Power the eCall system up (e.g. by switching the ignition ‘on’ or activating the vehicle's master control switch, as applicable) and verify that the malfunction indicator illuminates shortly afterwards. 2.1.4. Power the eCall system down (e.g. by switching the ignition ‘off’ or deactivating the vehicle's master control switch, as applicable) and restore it to normal operation. 2.1.5. Power the eCall system up and verify that the malfunction indicator does not illuminate or extinguishes shortly after illuminating initially. 3. Modification of type of 112-based eCall in-vehicle system or STU 3.1. When the manufacturer submits an application for revision or extension of an existing type-approval for the purpose of including an alternative GNSS antenna, electronic control unit, mobile network antenna and/or power source components, no retesting of 112-based eCall in-vehicle system components shall be required for the purpose of fulfilling the requirements of this Annex, provided that those type-approved components possess at least the same functional features and that they are indeed covered by this Annex in accordance with Article 5(3).
