Electrical and electronic subassemblies (ESA) in vehicles have become increasingly important in recent years. They are present in modern vehicles in large numbers and with different functions and tasks. cetecom advanced can take into account regulatory aspects as well as industry requirements.
cetecom advanced offers various testing and certification services according to the specifications of different manufacturers:
cetecom advanced is recognized for E-Mark approval according to:
We have been active in the testing and certification of emergency call systems since 2017. As part of the introduction of the eCall emergency call system for vehicles in the EU, we were involved at an early stage in the standardization and establishment of the specifications for eCall systems.
We also offer services for ERA-GLONASS, the counterpart of eCall for the Eurasian Customs Union, including ERA-GLONASS certification.
In the course of further developing our testing services, we have continuously invested in the modernization of our test laboratory for automotive radar systems over the past years. In particular, we have integrated new measurement equipment into our test environment to delight our customers with faster measurement times and higher precision in regulatory testing:
Thanks to new measurement techniques and a new signal and spectrum analyzer, we are able to reliably determine the most important parameters of your products up to 85 GHz without external mixers. This means we are ideally equipped to test future generations of broadband automotive radars. Even if the harmonics go higher, no problem for us! We cover the frequency ranges up to 325 GHz with our further calibrated “measuring stations” and the competence of our team.

Our laboratory in Essen is accredited by the DAkkS according to DIN ISO 17025 to carry out a wide range of radio tests. Detailed information on the scope of our accreditation for our laboratories in Germany can be found in our accreditation overview.
Our know-how and competence in the field of automotive EMC is reflected in the designation of cetecom advanced as a technical service (E1), among others for EMC. In our laboratories in Essen we perform test services for electromagnetic compatibility according to UN-R 10 series of amendments 06 (annexes 4-6 and 11-16).
Engine electronics
In a modern car there are up to 100 engine control units (ECUs), commercial vehicles have about 40, plus around 20 to 30 actuators that pick up the electrical signals from the ECUs and initiate mechanical or physical processes.
Transmission Electronics
Chassis electronics
Driver Assistance Systems
Passenger comfort
Information/entertainment systems
Electronically integrated cockpit systems
All vehicle electronic components must meet electromagnetic interference (EMI) and electromagnetic susceptibility (EMS) specifications. In this way, manufacturers ensure that unwanted electronic emissions remain within tolerable limits and that the vehicles are insensitive to external sources of interference – other electronic vehicle components, but also, for example, TV transmitters and mobile phone base stations. This is determined in tests for electromagnetic incompatibility (EMC).
Vehicle emergency call systems make an emergency call in the event of an accident – either automatically or at the touch of a button. eCall, for example, triggers a call to the single European emergency number 112. The system sends a data record to an emergency call center, which provides information about the accident situation. The minimum data record contains:
In addition, on-board security systems can transmit other data, for example:
