does this mod work on 2010 limited?

Thanks all, Just did this to the Wife's 2010 RAV4. Doors lock when shifted into reverse or through reverse (backup lights light). It was harder to find the “wire taps” than to do the Mod.

 

It was harder to find the “wire taps” than to do the Mod.

AutoZone sells them in a four-pack, which is perfect for this mod.

 

Anyone know what to connect if I would want the doors to unlock when the car is turned off, and not put into park?

 

Tried conecting both pinks (1 lock | 1 unlock) but it didnt work.

*** Eitingon - did you ever get a chance to check your lock/unlock setup?

My setup for locking doors when reverse lights come on:

Green ==> Bottom Pink (lock)
Blue ==> Upper Pink (unlock *diconnected*)
Violet ==> Red (bottom red wire on fuse block - backup lights)
Red ==> Grey (constant +12 volt)
Black ==> Ground (kick panel bolt)

 

What's the difference between using the relay's and the pulse generator? I'm just looking to auto lock when going from park to drive. The relay is $6 on eBay which is a lot cheaper than the pulse generator.

Also, I took a look at the pdf and on the last page, what's the purpose of the double sided tape to mount the relay? Maybe it'll be self explanatory when I do it but I'm just getting a feel for the mod now. Also, from the pictures, I don't see the t-taps added so I'm assuming whenever it says something like "Connect the wire 30 of the relay to this pink wire" that means to tap the pink wire with wire 30. Am I right?

 

hey guys..I purchased the [FONT=&quot]452T [/FONT][FONT=&quot]relay but I am very new to wiring...How am I supposed to "connect" these wires to the RAV4 wires? Sorry for the silly question![/FONT][FONT=&quot]

With t-tab splice like this

Or quick splice like this

Make sure you use a splice with an appropriate gauge (normal 14 to 22) to get a solid connection.

 

thanks for the videos! makes it much easier now...which method is more reliable? splice ?

 

I have used quick splice (since it was the only kind available at Walmart) and found sometimes it was a challenge to crimp while holding both wires. Haven't tried t-tab but would think it may be easier because you will deal with only one wire at a time.

Both methods are reliable if you use correct gauge. Anyway, you should use t-tab if the wires are not the same gauge.

 

Well, I'm more confused than normal.

My pink wire that is in the middle of the bottom row, of the bottom plug,
has +5 volts on it all the time. When I operate the lock button, the voltage goes to 0, release the button and voltage goes back to + 5 volts.

Can somebody please explain to me how the pulse generator, that I believe puts out either + or - 12 volts will lock or unlock the doors.

OR have I got the wrong plug/wrong wire?

THANKS, Dave

 

I know this is an old thread but... I've been a lurker and a non-poster for a while so I wanted to add to the forums a bit, so here it goes.

Great modification! Took about 10 minutes - and it was a lot of fun. Thanks guys for the info, my 2011 RAV4 now unlocks when in reverse.

Great stuff here - I hope I can contribute more as the months/years move along.

 

Now there is a much easier and cheaper solution that doesn't require any wiring at all:

Here's a quick review of the auto door lock module from China. I ordered it on March 7, they shipped it on March 15, and I just got it today, April 1. Total cost was $15 with free shipping (slow) and now the price has dropped to a little over $13:

Automatic Door Lock Closing CANBUS OBD system For TOYOTA New Vios Corolla RAV4 Car speed lock device Free shipping on Aliexpress.com

Installation is truly plug and play and takes 5 seconds. Simply plug the unit into your OBD port under the dash. When the car reaches about 12 MPH, (20 KPH), the doors lock. If you stop and one of the doors is opened and shut, the doors will re-lock once you reach 12 MPH again. When you open one of the doors, the hazard lights will blink 5 times. When you shift into Park, all the doors unlock, and when you open the door to exit, the hazard lights blink 5 times. There is no programming, and no options to set. I don't care for the hazard lights, but I guess it doesn't hurt anything. All in all, you can't beat it for the price.

 

Pooh!

I bought the pulse generator not too long ago, thinking one day ill do the mod. Now this comes along...

 

Does anybody know if it's possible to close all windows automaticly when leaving the car and lock it by central locking ?

 

No RAV4 that I have ever heard of can do this from the factory. It could probably be done by installing some aftermarket system. Perhaps some of the more advanced alarm systems offer those features.

 

Many Thanks ! That's exactly what I'm looking for

 

Please keep us updated on this.

I looked at the link as well, looks promising. If the brown cable is to go to the lock trigger, where does the red one go?

 

unfortunately it appears that module has been discontinued

 

It is NOT discontinued, here is the new link:

Edit: OK, I see now that you meant the Directed 452T module is discontinued. I can see why it was discontinued when you can buy the Chinese module for 13 bucks that is plug and play, locks the doors, re-locks the doors after you stop and open one, and unlocks the doors when you remove the key.

 

Sorry for reviving old thread.. but I just tried to install this module... But to confirm.. yes, you can unlock and lock with just one module.

I got everything to work following JuneBug's instruction on page 1 (To lock and unlock).

I opted to wire the blue wire to the upper pink (to unlock doors upon parking).

On shift to reverse, all doors lock.

However, on shift back to park, only the driver side unlocks. I want it to unlock all doors....

For unlocking, I used the upper pink cable is on the second row from the bottom, on the left.
Do I need to send a double pulse? (how?) Or did I get the wrong upper pink cable to unlock all doors? Any help is appreciated.

I was never able to use techstream to unlock all doors on one key press. Probably because dealership had installed a alarm system.

Hey sorry for reviving such an incredibly old thread. Hopefully you've fixed the issue after all these years, but I wanted to document the fix to this for future readers as I'm attempting to install the door lock pulse generator myself. From what I understand of the service manual wiring diagrams, to fix your problem I think you need to tap into the black wire instead of the upper pink wire for the unlock signal.

In your case I think what's happening is that you're using the "key unlock" to trigger the unlock signal. By default, the 452T unit only sends a single pulse, and the "key unlock" would be the equivalent of pressing the unlock button once on the key hence only the driver side door unlocks. To unlock all doors, use the black wire which should simulate an unlock button press on the driver's side power window switch and should unlock all doors with one pulse only.

So the overall wiring would be:
Green (425T) - Lower Pink (RAV4, lock signal, bottom row middle pink wire, pin #3)
Blue (452T) - Black (RAV4, unlock signal, bottom row leftmost black wire, pin #8)
Red (452T) - Grey (RAV4, constant +12V, upper rightmost grey wire, pin #2, or can use a fuse tap from constant +12V in the nearby fuse box)
Black (425T) - Ground (RAV4, ground, to nearby ground bolt for chassis ground)
Violet (452T) - Red (RAV4, reverse signal)

Doing this should lock all 4 doors when shifting from park to reverse, and all 4 doors should unlock when shifting back from reverse to park.

Now, the problem is this method breaks down when you continue to shift from reverse into drive. Since the 452T can only receive one activation input, shifting from reverse to drive would inactivate the reverse signal and the 452T module would send an unlock pulse as a result. The overall sequence would then be:

1. park->reverse - lock pulse
2. reverse -> drive - unlock pulse (at this point, you'll be in drive and the doors will not be locked which defeats the entire point of this module)
3. drive -> reverse - lock pulse
4. reverse -> park - unlock pulse

Therefore, I don't believe it's possible to use one 452T module to control both lock and unlock while using reverse signal as the activation input.

A workaround would be to use switched +12V power instead of a reverse signal as JuneBug described in the first post. Using switched +12V power will lock the doors when the ignition is turned on and unlock the doors when the ignition is turned off. To do this, change the activation input to be:
Violet (452T) - Blue (RAV4, switched +12V power, bottom rightmost blue wire, pin #1)

What I personally did was use switched +12V power as the activation input and door lock only. I left door unlock unwired since the front driver & passenger doors can be opened using the interior handle with one pull even when locked. I don't have rear passengers 99% of the time, so this was not a problem for me.

Best of luck to anyone that comes across this thread in the future!

Thanks
