Product Description

Vehicle emission characteristics are monitored and observed through Onboard Diagnostics (OBD). This means that each emission relevant ECU needs to support the OBD diagnostic. Over the last few years, because of OBD regulations, ECUs other than Powertrain are also required to support the OBD compliance.

ElectRay's eSAR.OBD stack is based on ISO 15031-5 standard and compliance with AUTOSAR R4.4.0. The eSAR.OBD stack is designed to be used in automotive, commercial vehicles, three wheelers and motor bikes ECUs. The Diagnostic trouble codes and fault memory is part of the eSAR.OBD stack. The standalone configuration tool helps to customise the features to meet the end application requirements.

The eSAR.OBD stack can be used in AUTOSAR or conventional ECU software environment. It can also be configured to accommodate the memory needs of the small footprint ECUs.

Note: NV data storage handling implemented as per the AUTOSAR standard using standardised API's and can be easily ported with any third party Flashing libraries.
