Differences KWP versus UDS ODX at Volkswagen and Audi Slide 2 ODX = Open Diagnostic data eXchange (ASAM/ISO-Standard) ODX Begriffserklrung What sigifies ODX? ODX describes all diagnostic data, which is necessary for the data exchange between (VAS) testequipment and the ECUs in the car. Slide 3 Motivation for the introduction of ODX What is changing in the ECU and the tester with KWP 2000 light plus VW / Audi- specific SensorsActuators raugh values Calculation Application with ISO TP / UDS / ODX: Application Calculation ISO-API commutability through standardized interfaces SensorsActuators raugh values Slide 4 Comparison KWP 2000 versus UDS / ODX Visualisation of the function read measure values old ? ? actual: missing information Slide 5 Comparison KWP 2000 versus UDS / ODX Visualisation of the function read measure values new any selection new ECU with ISO UDS/ ODX with description and scale unit with ISO UDS/ ODX Slide 6 Comparison KWP 2000 versus UDS / ODX Actuator test with KWP2000 Complicated statemachine in the ECU indicator(in the mirror) mirrorfunction Motor for central locking Ilumination run up window lifter lower window lifter leaving home lights Activate actuator test VAG-Codes.xls 85%EinAusInaktiv ECU response: fix measure valueblock Slide 7 Comparison KWP 2000 versus UDS / ODX Actuator test with UDS / ODX Indicator (in the mirror) mirrorfunction Motor for central locking Ilumination run up window lifter lower window lifter leaving home lights activate actuator ECU response: Measure values statemachine in the tester Slide 8 Comparison KWP 2000 versus UDS / ODX Visualisation of the function selectiv actuator test actual: no function- input possible!
