2011 Tacoma with the RS3200 Plus (TVIP V5) alarm

Does anyone with a 2011 have the RS3200 Plus alarm installed and if so do you have the ignition controlled door lock feature? From what I've been able to determine, with the previous version, RS3200 (TVIP V3), ignition controlled door locks could be enabled/disabled, but with the Plus version there is no mention of the feature in the owners guide. The local parts department also told me only the Plus version is compatible with the 2011.

I'd like to stay with the OEM products so I don't have to splice into the wiring harnesses but that being said, I also came accross a cheap alternative, < than $20, and that's the Directed Electronics 452T Door Lock Pulse/Double Pulse Generator. Does anyone have experience with installing this unit and how to find the needed wiring on the truck to tap into? Below is the link to the 452T wiring diagram. Thanks for any insight on this matter.

I have a 2015 with that alarm system. I also do not have that feature. My research concluded that I do not have this feature to enable or disable.

 

Thanks haydendoesmith. It just seems odd Toyota would discontinue the safety feature in the newer alarm version.

 

Do you already have the RS2300 installed on the truck? If so then the 452T would be fine for adding ignition controlled door locks. If you don't already have the alarm in the truck then I would just go with an aftermarket unit as it'll give you a lot more flexibility on what you can add to it down the line.

Either way here is a link for all the alarm wiring for your truck.

Thanks for the link gstodd, that info will be very helpful. I don't have the RS3200, just the Toyota baseline engine immobilizer and the truck doesn't get driven that much so I don't forsee adding remote start capability, etc. Do you have experience with the 452T? I was also wondering if there's a way to trigger the locks when the vehicle is shifted in and out of Park. Or possibly use the daytime running lights? With the engine running, releasing the emergency brake triggers the drls and I don't think they turn off until the engine is shut down which would be a good time for the unlock to trigger. Any thoughts?

 

Yeah, I've got plenty of experience using the 452T. DEI has made it for decades, even as far back as when I was a car stereo installer back in the 80s and 90s.

I wouldn't recommend using the DRLs. I don't have them on my truck but if I remember correctly they turn off when you use the turn signals and aren't active with the parking lights on. It would be possible to have it trigger when being shifted out of park. You would need to find the wiring for the park/neutral switch and test to see which wire indicates when it's taken out of park. Might need to use a relay so that it triggers when there is no power to the wire but the key is on as it probably does not switch polarity when coming out of park. There should be wiring for this at both the ECU and on the transmission but you would have to find it.

 

Great point regarding the DRLs. Obviously I didn't think that one through very well . . . When I ordered the 452T earlier this week, I was reading some of the reviews and one person with a Rav mentioned using the Park trigger and I thought that might a little nicer than using the ignition switch. I'll see if I can hunt the switch wires down to see what they may tell me.

 

So I did finish the 452T installation a few weeks ago and I'm very pleased with its performance.

Using the +ignition lead for a trigger as the directions suggest had me worried about a possible lockout situation if I were to start the truck, leave it running, exit the vehicle for some reason and then have the door shut. I thought about picking up the park lead from behind the glovebox or on top of the right side of the instrument cluster and then switching the lock/unlock wires so I wouldn't need an additional relay. By switching I mean taking the green lock wire from the 452T, running it to the gray unlock wire on the truck and taking the blue unlock wire from the 452T and running it to the blue/white lock wire on the truck. That way when the truck was shifted out of park I should get a pulse to lock the doors and when returned to park it would generate the pulse to unlock the doors. Sounds workable in theory???

After a bit more research though I ended up using the hot side of the ignition key interlock solenoid as the trigger for the violet input wire on the 452T and connected the lock/unlock pulse wires to the respective lock/unlock wires on the truck as depicted in the 452T wiring diagram. When the key is inserted in the ignition and turned past lock (acc, on, start), and the shifter is moved from the park position, the solenoid goes hot triggering the door locking pulse and then when the shifter is returned to park, the solenoid de-energizes and the 452T generates the unlock pulse. I think the system as it's wired now works as well as any OEM alternative and after having to manually lock all the doors previously, I cannot count how many times I'd forget to unlock them when I'd get home and walk around to the passenger side to get something out of the vehicle only to find the doors still locked.

I highly recommend the Directed 452T and hopefully this thread will be helpful to anyone contemplating installing this convenient safety feature in their vehicle.
