Topology

Generating Vehicle Topology Diagrams Using Harness Data

Topology was designed to reduce the mean time to repair for a vehicle that fails an End of Line (EOL) test system. By generating a wiring diagram on the fly of the circuits and connectors relevant to the failure(s), Topology reduces repair time by narrowing focus from complete and complex vehicle wiring system down to circuits and connectors related to the failure.

Topology Diagnostics maps vehicle test and diagnostics data from MAHLE testers with vehicle harness data to generate near real-time VIN and fault specific network diagrams, expediting the diagnostic process and minimizing any vehicle damage.

  • Simplifying the repair process from cryptic Diagnostic Trouble Codes (DTCs) and binders of wiring diagrams down to a tangible location that the repairman could begin looking
  • Prioritizes the locations to be checked first based on the common connectors related to the EOL failures
  • Learns over time by giving the repairman the ability to choose a different connector as the cause. Over time, the priority adjusts based on the feedback
  • Reports the source of the failure by using MAHLE’s reporting system to help find and fix the source of the failures
  • Uses existing RDBS (Repair Bay Diagnostic System) hardware to run Topology simply by selecting the failure of interest and click a button
  • Leverages data used to generate Topology that is available before the plant build events and can be used to speed the learning curve during new vehicle launches
