Ann Arbor, Mich.ETAS Inc., a subsidiary of ETAS GmbH, has released the ES4440 Compact Failure Simulation Module to insert electrical faults in the wire harness of a powertrain Electronic Control Unit (ECU) to verify the software and hardware passes diagnostics tests, like OBDII.
The ES4440 provides a blend of high current channels to simulate errors in high current components like fuel pumps or glow plugs, and high voltage channels to simulate errors in high voltage components like piezo-electric fuel injectors. High current channel faults are simulated using precision MOSFET transistors. High voltage channels use relays to simulate single or multiple faults. If additional fault channels are needed, the user can daisy chain up to 15 ES4440s to the master unit.
