Testing the connections of airbag ignition elements poses a high safety risk for the testing staff. Any defects in the wiring harness or in the test system can cause an airbag to be triggered. The MTS Airbag Tester provides a safe test method for testing the electrical connection between airbag ignition elements and wiring harness.
In the new MTS-Airbag Tester, the test electronics are located in a separate housing that is galvanically isolated from the rest of the testing system. Preferably, the test electronics are installed in a hand-held adapter. The galvanic separation prevents electrical energy from reaching the airbag’s ignition elements, which could trigger the airbag. The data exchange takes place via a dedicated CAN bus.
Before each single measurement, a self-test of the MTS-Airbag Tester is carried out. This ensures that the electronics used for measurements are functioning correctly and are properly adjusted. Only if the self-test has been successful does the test of the connecting wires of the ignition pill start. The MTS-Airbag Tester checks that there are no short-circuits to ground or to the vehicle voltage. The test results show whether the airbag is correctly installed or whether there is a fault such as a short-circuit, cable break or an incorrectly connected connector.
The test results recorded by the MTS-Airbag Tester can be transferred to a superior test system. In this way, a recorded proof of the safety test carried out can be created.
The airbag test can be easily integrated into the DSA PRODIS test system. In addition, the MTS airbag tester can also be operated stand-alone, in which case the results are displayed via LEDs and digital inputs/outputs.
