at end of article.
- Ensure hood is closed. Turn ignition on (engine off). Using DRB-II, read Vehicle Theft Alarm (VTA) hood ajar switch status. If DRB-II does not display CIRCUIT CLOSED, go to step 4).
- If DRB-II displays CIRCUIT CLOSED, disconnect hood ajar switch. Switch is located on left front fender. If DRB-II does not display CIRCUIT CLOSED, check alignment of hood ajar switch. If alignment is okay, replace switch. Perform VERIFICATION PROCEDURE VER-1.
- If DRB-II displays CIRCUIT CLOSED, disconnect Vehicle Theft Alarm (VTA) module. See Figure . With DRB-II in ohmmeter mode, check resistance of Brown/Tan wire of hood ajar switch connector. If resistance is less than 5 ohms, repair short to ground in Brown/Tan wire. Perform VERIFICATION PROCEDURE VER-1. If resistance is more than 5 ohms, replace VTA module. Perform VERIFICATION PROCEDURE VER-1.
- If DRB-II did not display CIRCUIT CLOSED in step 1), disconnect hood ajar switch. Connect jumper wire between Brown/Tan wire of hood ajar switch connector and ground. Using DRB-II, read VTA hood ajar switch status. If DRB-II displays CIRCUIT CLOSED, replace hood ajar switch. Perform VERIFICATION PROCEDURE VER-1.
- If DRB-II does not display CIRCUIT CLOSED, disconnect jumper wire and access VTA module. See Figure . With VTA module connected, connect a jumper wire between terminal No. 12 (Brown/Tan wire) of VTA module and ground.
- If DRB-II displays CIRCUIT CLOSED, repair open Brown/Tan wire between VTA module and hood ajar switch. Perform VERIFICATION PROCEDURE VER-1. If DRB-II does not display CIRCUIT CLOSED, replace VTA module. Perform VERIFICATION PROCEDURE VER-1.
