Calibration and Validation of ECU Diagnostics Gary Hickman ETAS



2

− Diagnostics is an essential part of the ECU software (>40%) to ensure e.g.

− Serviceability (easier root cause analysis and mal function detection)

− Safety (guarantee system safety in case of mal functions)

− Conformance to legislation on emission related systems (OBD)

− Calibration and validation of ECU diagnostic functions is an important use

case for many INCA users, e.g. for

− Calibration of diagnostic thresholds, error path and freeze frame content

− Evaluation of onboard diagnostic functions / monitors

− OBD validation (correctness of MIL status, DTCs, PID values, IUMPR, etc.)

− Calibration and validation of ECU diagnostics is supported with ODX-LINK,

the integrated diagnostic solution for INCA

INCA and ODX-LINK

Overview

− ODX-LINK is an ODX based, integrated diagnostic solution

for INCA supporting Measurement, Calibration and

Diagnostics in one tool and with the same HW

− Main Features

− Integration of Diagnostic Measurement Signals in INCA

• Selection in Variable Selection Dialog

• Joined visualization together with measurement and calibration

data in the same INCA experiment

• Joined recording and analysis of measurement and diagnostic

data in the same MDF file

• Usable for trigger conditions and calculated signals

• Available at MCD-3MC , ASAP3 and COM interfaces of INCA

− Out of the box OBD-on-CAN support with OBD Scan tool UI

− Snap shot documentation of diagnostic data (XML, Html, txt)

− Multiple Diagnostic windows for many use cases

Different tools => no synchronization => no joined data visualization => tool switching required

Separate HW and cables => higher costs => possible ECU access conflicts

Separate logfiles and analysis tools => no joined data analysis => higher analysis effort

• One tool for Measurement, Calibration and Diagnostics

• Joined data visualization of MC and D data in the same experiment

• No additional HW for Diagnostics • Joined recording of measurement and

diagnostic data into the same MDF file

• Joined data analysis of measurement and diagnostic

• data with the same tool



7

− Diagnostic Signals are provided like normal measurement signals

in INCA

− Diagnostic Signals selectable within Variable Selection Dialog

− Joint data visualization of MC and D measurement data in the same INCA

experiment windows (Oscilloscope, tables, measurement windows)

− Definition of Calculated Signals based on Diagnostic Signals

− Recording of Diagnostic Signals to INCA MDF files

− Definition of combined MC & D trigger conditions

Integration of Diagnostic Signals in INCA (1)



8

The integration of Diagnostic Signals is based on:

1. ODX files

− Describes the diagnostic interface of an ECU or vehicle

• Diagnostic services and service parameters

• Decoding of ECU responses to physical values

2. Diagnostic Signal List

− Defines the Diagnostic Signals and how to retrieve them via ODX

Diagnostic Signals for OBD (e.g. PIDs, DTCs)

− OBD protocol and diagnostic data is standardized (SAE J1979)

− ODX files and Diagnostic Signal List provided by ODX-LINK

=> Start right away with OBD measurement in INCA. No additional files needed !

Customer specific Diagnostic Signals (UDS, KWP2000)

− Use ECU specific ODX data (similar to ECU specific A2L data)

− Create a Diagnostic Signal List (can be done with ODX-LINK in the Experiment)
