ETAS ODX-LINK allows direct comparison of data from both OBD scan tool and ETK in ETAS INCA
Bosch Engineering GmbH deploys the ETAS INCA software tool in tandem with the ETAS ODX-LINK diagnostic add-on for the synchronous acquisition of OBD signals from the CAN bus, and of ECU signals from the ETK interface, by means of an ES59x interface module.
In compliance with legal requirements, emission-related ECUs must furnish a standardized OBD scan tool interface for external access to on-board diagnostics. This interface
must be carefully tested before any ECU can be approved for series production.
For testing this interface, Bosch Engineering deploys INCA in combination with its ODX-LINK diagnostic add-on, plus the ETK interface and the ES59x interface module.
Through the OBD scan tool interface and the ETK interface, ETAS tools facilitate the direct acquisition of ECU diagnostic information and internal ECU data, respectively.
Thanks to the time-synchronous acquisition of ETK and diagnostic data, within the same INCA experiment, the ETAS solution provides a simple way of direct data comparison. This approach facilitates the efficient validation of the OBD scan tool interface.
