Hi, I can't seem to find anyone who knows how to permanatly disable the passive alarm system. I see that many have asked this question but no answers have been given except for a 1992 Chrysler New Yorker that says find the green wire in drivers door that leads to power lock and ground it to disable alarm. Does this apply tpo a 1995? Another suggested, "find 21 wire plug behind glove box, start car and disconnect jack. I found 3 that are next to impossible to get at. What happens when you shut the car off can it be re-started? My mechanics are daunted and my daughter says the car is haunted. Courtesy ligts flash on and off, door locks dance up and down. We have no keyless remote to disarm it. Any ideas? Money is very tight for both of us now, she needs it for school and car problems are not acceptable excuses these day. Please Help!

Hello .. thanks for the donation .. much appreciated

There is NO way to completely disable the immobolizer on this vehicle ... the VTSS (vehicle theft security system) is controlled by the BCM (body control module) .. which then sends a signal to the PCM (powertrain control module) to allow injector function when VTSS is disabled (turned off) with key or remote ... if the PCM does not recieve this signal from the BCM then it cuts out injectors and the vehicle will not start ..so grounding a wire in the door will not help ... unplugging the connector from the BCM will not help as the vehicle will not start .. if there is no power to the BCM the PCM does not recieve the correct signal and the injectors are not allowed to function ...

****VTSS can be triggered from several areas: doors, trunk key cylinder and ignition switch. VTSS has a panel SET light. SET indicator light flashes for 15 seconds during arming process. VTSS is armed by locking doors using power lock button or RKE. VTSS is disarmed through normal vehicle entry of unlocking door with key or RKE. Whenever battery power is lost or disconnected, VTSS will prevent vehicle from starting. When battery power is restored, system must be disarmed before vehicle will start*****

All the symptomds you are describing are related to the BCM .. this is where your fault lies .. the BCM controls door locks/courtesy lights etc. ... check the connector on BCM is not damaged or loose also check the wiring ??

Body Control Module (BCM) is located behind right side kick panel. See Fig. 12 . Open right front door. Pry off right dash end trim cap. Remove right side kick panel trim. Pull back carpet. Cut dash liner along perforations. Pull back dash liner.
Remove mounting screw and push-pin. Ensure ignition switch is in OFF position. Disconnect BCM connectors.

Your only other option is to have the BCM read by a diagnostic scanner to locate the actual fault or to see if the BCM is bad and needs replacing .. I suspect if the BCM is not giving fault codes then its a wiring fault somewhere or the BCM is bad !!! I know this is not the answer you were looking for but I hope it helps ... let me know
