Mobile network Item necessary because it is a function: a communication internal failure failure implies that the AECS cannot perform device its function. Electrical connection / GNSS receiver module communication failure GNSS receiver Internal failure Mobile network Electrical connection antenna GNSS antenna Electrical connection Crash Control e.g. crash detection sensor system, triggering Electrical connection Unit (CCU) device, … If not in good condition, then the automatic emergency call is not possible. If CCU CCU Internal failure internal failure verification is not part of AECC approval (Part Ia), then it shall be subject to AECD approval (Part Ib) Power supply Electrical connection Dedicated battery is connected This item only applies if a removable SIM SIM not present card is used. The state of charge, Back-up threshold for warning at Failure if the state of charge is at a critical supply (if fitted) the discretion of the level according to the manufacturer. manufacturer Verification of the performance of the AECC malfunction shall be conducted against the manufacturer's specification. This can be either by actual test or simulation. 7.5.2.2. Test procedure Self-test function verification test: 7.5.2.2.1. The following test shall be performed on an AECC on a representative arrangement of components. 7.5.2.2.2. Simulate a malfunction of the AECC system by introducing a critical failure in one or more of the 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 Technical Service. 7.5.2.2.3. Power the AECC up and verify that the AECC warning signal device illuminates shortly afterwards or the electrical signal is generated shortly afterward, whichever is relevant. 7.5.2.2.4. Power the AECC down and restore it to normal operation. 7.5.2.2.5. Power the AECC up and verify that the AECC warning signal device does not illuminate or extinguish shortly after initial illumination, or the electrical signal is not generated shortly afterward or is cancelled after being generated initially, whichever is relevant.
