EVIC Self-Check Diagnostics
The EVIC is capable of performing a diagnostic self-check on its internal functions. EVIC diagnostics may be performed using a DRBIII(R) or by using the following procedure:
- With the ignition switch in the OFF position, depress and hold the RESET and the C/T buttons.
- Turn the ignition switch to the ON position.
- Continue to hold both buttons until the software versions are displayed, then release the buttons.
- All of the VFD segments will illuminate for 2-4 seconds. Check for segments that do not illuminate or illuminate all the time.
- When the self-check is complete the EVIC will display one of the following messages: PASS SELF TEST, FAILED SELF TEST or NOT RECEIVING J1850 MESSAGE.
- To exit the self-check mode, depress the RESET button or cycle the ignition switch and the EVIC will return to normal operation.
If a communication fault is displayed, diagnose using appropriate procedure. See COMMUNICATION under DIAGNOSTIC TESTS. If a FAILED is displayed, the EVIC must be replaced.
