Viper 4105v Parking Light Troubles

Hey all,

I've been looking at the12volt posts and replies for about a year now, referencing them for my own remote start install even before I knew what kind of remote start I would buy. With the invaluable help of a forum post here, I was able to install my own system. However, I've run into a problem I cannot seem to find an answer to, and I finally created an account here to ask for some help.

I have a 2010 Ford Crown Victoria that I've installed a Viper 4105v R/S on. It's working excellent so far, and I've got my options all set up the way I like them. However, there is one minor (or major depending on circumstance) problem; when I hit the lock button on my fob, the horn honks once and the parking lights flash (as soon as the vehicle is secure) once. However, when I remote-start the vehicle, I have the settings setup to, in theory, turn on the parking lights once a successful start is completed. This doesn't happen, and in the event of a failed R/S, the parking lights do not flash in order to identify the reason for failure, as they are supposed to. I know they've got to be hooked up right, as they're working fantastically when I hit the lock button: What could be the problem here?

Any help would be greatly appreciated. It's not major, but I'm never sure when the car is started and when it isn't unless I go outside to check (defeating the purpose) or open a window (which can sometimes not be an option in -20F).

I feel some of this is self-explanatory, but I will group it all together anyway:

Vehicle year: 2010
Make: Ford
Model: Crown Victoria
Trim: Police Interceptor (vehicle not equipped with Ford PATS)
Ignition type: Keyed ignition
Mileage: 133k
R/S System: Viper 4105v 1-way

Thank you all!

I'm guessing you're using the negative trigger for parking lights. My only suggestion is to try the positive parking lights wire, essentially bypassing the LCM.

My ex once told me I have a perfect face for radio.

Did you hook up the Park lights? The thicker white wire with the fuse on it? park lights should flash, once when it's locks, and twice for unlock.. and when it's "running" they should come on constant.

Viper will flash the park lights for "startup diagnostics", (reason why it didn't start) right away

5 flash brake wire active
6 flash Hood open
7 Flash Manualy tranny
8 neutral safety.

but for shutdown diagnostics you have to press and hold control button/ turn ign on /off and then release button to see why it shutdown.

My WAG is that the flash you're seeing is being generated by the vehicle in response to the lock input. Not being generated by the Viper.

Disconnect the white light flash wire from the vehicle and test / cycle the Viper to be sure you are getting the correct outputs from the Viper. Once verified that the Viper is performing properly, work on the interface to the vehicle.

I personally prefer the (-) trigger light flash, but using (+) trigger is generally simpler and less prone to error by a novice. When set for (+) trigger, you should hear an audible relay click from within the Viper module. In (-) you won't. (This is one of the reasons I prefer (-) trigger light flash. The absence of the loud clicking relay makes it more difficult to locate the module. I utilize the GWA output for additional protections. Finding, and unplugging the module will defeat these additional sub-systems. I go way out of my way to conceal the module. I don't want it to be found.)
