Test 25A - Blank EVIC Head Monitor
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION
. For appropriate wiring diagram, see WIRING DIAGRAMS
at end of article.
- Press TIME button on Electronic Vehicle Instrument Center (EVIC) panel. If EVIC display is not blank, retest system. Perform VERIFICATION PROCEDURE VER-1. If EVIC display is blank, turn ignition off.
- Ensure all doors, hood and trunk are closed. Wait 4 minutes. Simultaneously press and hold FUEL, TEMP and INFO buttons on EVIC panel. If EVIC performed self-test, go to step 4). If EVIC did not perform self-test, remove and inspect fuse No. 12 from fuse block. See Figure . If fuse is okay, go to TEST 25B.
- If fuse is blown, put DRB-II in ohmmeter mode. Check resistance of Pink wire (in fuse block) from fuse No. 12. If resistance is less than 5 ohms, repair short to ground in Pink wire and replace fuse No. 12. Perform VERIFICATION PROCEDURE VER-1. If resistance is more than 5 ohms, replace fuse No. 12. Perform VERIFICATION PROCEDUREVER-1.
- If EVIC performed self-test in step 2), check if self-test passed. Correct EVIC panel display for passed self-test is E2-0, E3-0, then END OF SELF-CHECK. If self-test did not pass, replace EVIC head monitor. Perform VERIFICATION PROCEDURE VER-1.
- If self-test passed, disconnect DRB-II and EVIC head monitor connector. See Fig 1 . Check EVIC connector condition, and clean or repair connector as necessary. Using an external ohmmeter, check resistance of Violet/Brown wire between terminal No. 6 of EVIC connector and terminal No. 1 of Chrysler Collision Detection (CCD) bus data link connector. If resistance is more than 5 ohms, repair open Violet/Brown wire. Perform VERIFICATION PROCEDURE VER-1.
- If resistance is less than 5 ohms, check resistance of White/Black wire between terminal No. 5 of EVIC connector and terminal No. 6 of CCD bus data link connector. If resistance is more than 5 ohms, repair open White/Black wire. Perform VERIFICATION PROCEDURE VER-1. If resistance is less than 5 ohms, replace EVIC head monitor. Perform VERIFICATION PROCEDURE VER-1.
