Vehicle Door Module Electronics Testing Now Available

Testing of vehicle door module electronics now available

Posted in in Automotive, Production testing

Automotive door module electronics typically contain an array of electronic components, such as switches, antennae and speakers.

It’s important that these components are reliably tested at assembly stations during manufacture, in order to reduce the risk of faulty manufacture and passing incorrect components to later stages of the manufacturing process.

The Genix Test Unit provides a means of performing a number of electrical and communications tests on products at assembly stations during manufacture. The system has been designed for testing a range of electronic components within sub-assemblies, such as bumpers and spoilers, at the end of the production line.

The system has recently been enhanced to achieve complete testing of vehicle door module electronics.

The GTU is capable of testing a wide range of vehicle door module electronics, including:

  • Antenna entry – passive entry, passive start (PEPS)
  • Puddle lamps (Incandescent) – with RGB functionality
  • Switches – for door and window locks
  • LEDs – also known as ambient lighting
  • Tweeter speaker – door open warnings, for example
  • Intelligent Switch Packs – functionality such as mirror adjustment, via LIN

The test unit has a high I/O count supporting a wide range of simultaneous tests and includes PLC interfaces for test control, result capture and handshaking. It’s capable of providing both advanced continuity and functionality testing via LIN, CAN and PSI5 and optional other protocols, such as SENT.

Typically, test results are fed back to the PLC. Custom handheld devices can be provided for monitoring of test results or alternatively, these test results can be monitored via our real-time systems interface creation software, VISUALCONNX, with a custom GUI. The unit can be mounted in a wide variety of locations within the manufacturing environment. Plugable screw terminal blocks for I/O and power are provided with each test unit.

About Genix Test Unit

The Genix Test Unit helps engineers to ensure that the correct components are present, of the correct engineering revision and that they function as designed.

The system tests the presence and functionality of electrical components immediately after manufacture, following instructions given by the PLC of the assembly station.

Common devices tested include parking sensors, gesture sensors, PED sensors, cameras and lamps within vehicle bumpers, spoilers and door modules.

So, GTU helps vehicle sub-assembly manufacturers to verify electrical components and mitigate against the risk of delivering faulty equipment.
