How to Perform EVIC or EEC Actuator Tests

HOW TO PERFORM EVIC OR EEC ACTUATOR TESTS

EVIC ACTUATOR TESTS

After 4) ACTUATOR TESTS is selected from the EVIC MENU, the display will change to read as follows:

ACTUATOR TESTS
1) DISPLAY TEST

Select 1) DISPLAY TEST. The screen will display:

DISPLAY TEST
ACTUATING/COMPLETED

The DISPLAY TEST turns on every LED in the EVIC display, then turns them off. If all LEDs do not come on then go off, the test fails.

EIC ACTUATOR TESTS

After 4) ACTUATOR TESTS is selected from the EIC MENU, the display will change to read as follows:

ACTUATOR TESTS
1) INTERNAL CHECK
2) ALL SEGMENTS ON

Press the down arrow three times to view the rest of the tests. The screen will display:

ACTUATOR TESTS
3) SEQ SEGMENTS TEST
4) SEQ LEGENDS TEST
5) SEQ LAMP CHECK

Enter the number that matches the desired actuator test. The screen will display:

XXXXXXXX
ACTUATING / COMPLETED

NOTE: The top line will show the name of the selected test.

To determine whether or not any of these tests pass or fail, you must watch the EIC display as the test is being actuated. Each test passes or fails as described below.

1. INTERNAL CHECK - This is a test of the internal functions of the electronic instrument cluster. This test displays any fault codes that may be present. None of the diagnostic test procedures require you to perform the internal check test. Fault codes are accessible through the ELECT CLUST module menu and should be read from this menu. See "How to Read DRBII Fault Messages" found earlier in this Help 1.

2. ALL SEGMENTS ON - This test turns on all segments of the EIC display, then turns them off. If all segments do not come on then extinguish, the test fails.

3. SEQ SEGMENTS TEST - This test lights up every vacuum fluorescent bar on all gauges in the EIC display, then turns them off. If any bar fails to light up, the test fails.

4. SEQ LEGENDS TEST - This test lights up each legend in the EIC display one at a time, then turns it off. If any legend fails to light, or if two light up together, the test fails.

5. SEQ LAMP CHECK - This test lights up each of the following lamps in the EIC display one at a time, and then turns it off: Washer Fluid, Door/Deck, Check Engine, Seat Belt, Brake, and Check Gages. If any lamp does not light up and then extinguish, the test fails.
