iDatalink 45 second shutdown if no takeover

I just picked up a 2011 Ram 1500. I'm thinking about swapping out the Code Alarm RS that's in it for a Compustar/iDatalink setup. The range on the Code Alarm sucks and it's only one-way, not only that, but I already have a CM6200, ADS-ALCA and a set of 2WG9 remotes laying around. Anyway...here's my question.

I was looking at the iDatalink guide for this particular vehicle. The wiring diagrams don't look like anything special, but the RS take-over procedure is a bit of a turn off. According to the guide you only have 45 seconds to perform the take-over procedure after you unlock the doors. Is this a new safety feature iDatalink has started to implement?

I've used iDatalink bypasses for quite a few installs but this has me looking at other options.

For reference, this is the guide I'm looking at:

ADS-AL(DL)-CH4-EN
Available for: ADS-AL CA CH4
Rev. Date: October 28, 2015
Doc. No.: ##23958##

I just looked at the Fortin solution for the same truck and no mention of a 45 second window for takeover. Interesting.

When you are flashing the ALCA if i am not mistaken in the menu you can change that option to do a normal takeover! How are you Shafferny its been a ling time .

Yeah, it's been a while since I posted. I still stop by the forum from time to time. Just haven't been posting much.

I just looked at the menu settings. The two settings available are "normal take over" and "shutdown with door open". I'm assuming the shutdown with door open option is the one they're referring to in the guide. I'll have to give it a shot and see what happens I guess.

Thanks for the tip triniforever!

Good luck

The reason for this is so the truck can't be stolen under remote start. While under remote start, anyone can stick their finger in the ignition, turn it on, and steal the truck. 45 second window is required so this doesn't happen.

I understand that, but once the RS shuts down, wouldn't the vehicle also?

I mean, if you stuck your finger in the ignition switch to turn it to the ON position, hit the brake, and the RS shut down, wouldn't the vehicle look to see if there's a key(chip) in the ignition and if not, shut the vehicle down?

I guess I don't see where it would be any different than any other vehicle with a good old transponder key. Am I missing something?

Not if a thief turned the ignition with their finger before stepping on the brake.

No.

Yes. Your key is not cut like all other transponder keys. The immobilizer signal is what unlocks the cylinder. Don't take my word for it, all of this can easily be tested if you remote start the car while sitting in the driver's seat without the key. Remote start it, turn the ignition with your finger, then drive away.

Well, that didn't work out like I planned. You get the point though. Let me know if this still doesn't make sense. I may not be doing a great job explaining it.

Interesting Beegbie. I didn't realize it worked that way. Thanks.

Interesting topic.  I had the opportunity to see what happens on the 2013 Dodge Caravan in this Pictorial :
https://www.the12volt.com/installbay/forum_posts.asp?tid=134484

This install did not use the iDatalink ADS AL-CA flashed with the DL CH4 firmware.  It used the EVO-ALL with the V 74
Chrysler firmware.  With this set-up, at key take-over, you will see the Red security light come on briefly and the message
"Low Tire".  All very normal / common for these vans and causes no harm.

Anyway, I sat in the van a did a remote start.  After the remote start up was complete and the parking lights were on solid
for a few seconds, I used my finger to move the ignition switch to the RUN position.  The engine continued to run but
no Red light flash on the instrument cluster and no "Low Tire" message.  Next I stepped on the brake pedal and the
engine immediately shutdown.  My gut feeling is that the Red LED is the vehicle verifying for the keys' transponder chip.

It would seem that Fortin modules have this important safety feature handled properly.  I will have to test it on the next
ADS AL-CA w/CH4 firmware vehicle I do.  On this vehicle :  https://www.the12volt.com/installbay/forum_posts.asp?tid=140728
I did try the 45 second test only and the engine did not shutdown in 45 seconds as mentioned by the guide.  As a matter of
fact, the doors did not have to be locked for a remote start, also mentioned in the CH4 install guide.

Soldering is fun!

That's interesting Kreg. The Caravan you described behaves just like my truck does with the current RS that's installed, except I don't get the low tire light. The red security light flashes once or twice when I do the take over, which appears to be verifying that there's a valid key in the ignition. I haven't tried the finger thing to verify it though.

If the weather ever warms up, maybe I'll get to work on it.

Today got up around 40 degrees so I did the install of the CM6200 and ADS ALCA. Sure enough, there's only a 45 second window to do the take over or the vehicle shuts down. After remote starting, the vehicle locks the doors. When you unlock the doors you only have 45 seconds to do the take over. What's kinda weird is that you can start the truck with the doors open and it doesn't care. Lol

The bypass the previous installer used with the Code Alarm was a Flash Logic. The Flash Logic had no 45 sec take over and didn't lock the doors before or after remote starting. Interesting, being that it's an ADS product as well. Maybe it has an older version of firmware that doesn't incorporate the time out security feature.

Anyway, just posting this as a follow up.
