The following procedure shall be used to set-up the text fixture, load the necessary kernel and test software to validate the results. The intent of these test steps are to ensure the quality of EVIC’s production boards.

Analog Inputs
Use x5 22k resistors in series, powered from 5V to generate different voltages for each channel. See schematic below for wiring connector pins P4 and P5.
Digital Inputs and Outputs
Use x7 inverters on pins 1-7 on connector P3. The inverters are used to convert ground to 12V. No inverter is needed for pin 8. See schematic below for wiring connector pins P3 and P5.
CAN Channel
A test EVIC board is needed to transmit CAN messages onto the CAN lines of a production EVIC board. Each CAN line (High and Low) will need to be wired to both the Test and Production EVIC boards.
EVIC Verifier Test Application
Test Verification application will need to be loaded onto production EVIC board prior to testing.
Please select “skin.xml” file from the provided software to selection application.
2. Power “Off” and “On” EVIC board. The test application will automatically start and execute the tests for each analog and digital inputs and outputs. The tests are normally done in 2-4 seconds.
3. If the board Passes, the following message will appear:
4. If the board Fails, the following message will appear:
Note:
If the CAN messages are not set-up, the application will continue to test in absence of CAN.
