SXV10 Camry Keyless entry questions

[Mr Ree]

Hi TS'ers,
When I bought my 97 Camry wagon, although it was the povo spec base model, it luckily came with the factory alarm with keyring fob, so it can be locked/unlocked remotely etc.

A few years down the track, it started playing up, and stopped working entirely. Upon inspection, it was found that the wires going into the rear hatch had worn over time due to the opening/closing of the hatch, and a couple of wires had snapped and shorted out.

After fixing all of the wiring, the factory locking still didnt work, so I pulled apart the dash and removed the "computer integration relay" Part# 82641 YCO21, and discovered there was a cooked component on the board.

I went to a wrecker and bought one from another camry wagon and fitted it, but still no dice.

I wasnt able to confirm whether or not the wrecked car actually had the factory security system installed, so my question is, id there a difference between the part for models that did/didnt get the factory alarm, or have I potentially burned out something somewhere else?

Mark, is this something you could look up on your EPC files, perhaps?

Thanks for any help

Does it have the lock unlock
button in the centre console behind the gear lever?

The key-less entry system is a dealer option as is piggy backed into the car. The receiver etc is mounted under the drivers seat and wires run along the sill and into the kick panel. Three scotch locks go to power, door sense and one other wire while the main plug piggy back into the CDL module. The main fault is the factory remote and is much cheaper to go after market.

Give me a shout if you did want to go down that route

Yes, it does.

Thanks for the info.

I am familiar with the setup you described as the JZA80 factory keyless entry is the same, but I dont think my Camry has anything under the drivers seat.

The remote is the type that has the docking station inside the glovebox, and is programmable from there. The remote has always worked too, and luckily I have two of them.

Not really looking to go aftermarket, as chances of somebody wanting to steal a Grandpa spec Camry is pretty unlikely, but I would just prefer to have the system thats currently in the car, operational again.

The main reason is when its pissing down, its nice to be able to simply press the button as you near the car, and avoid having to get soaked while fumbling to get the key in the lock.

Thanks

[matt dunn]

Yes, it does.

May just pay to check that the switch is not jammed in one direction,
have struck this quite a few times at work,
and it stops the central locking from working.

I've got some reading for you that I'll email through to you Reith.

But that new intergration relay you fitted, I think this will be stopping you from using your current remotes or getting them to work. Unless you can locate the rego/VIN off the Camry you got it out of.

[Mr Ree]

Yes, it does.

Thanks for the input, Matt. The switch in the console appears to be fully functional as I use it often.

Thanks, Mark. I had pretty much assumed that was the cause of the issue, but was just hopeful I could simply swap it and solve the problems.

Absolutely zero chance of finding out the rego number as it was 5 years ago that I bought the part, not to mention the $&#$% head who owns the wreckers will never get a dollar from me again due to being an arrogant c**t everytime I have ever gone there lol.

[KinLoud]

Yes - my first thought was related to the central locking button also...
Have had that switch spoil the system in the past...
My experience with both factory and aftermarket systems...
Factory FTW every time.
Good luck

[Mr Ree]

Absolutely agree, factory security FTW, especially on something as uninspiring as a Camry Wagon.

Now that two people have mentioned the central lock button, Im going to remove it and clean it, just for peace of mind, although Im 99.9% certain the reason for the problem is the shorted out wires frying the integration relay.

Thanks guys

[matt dunn]

now that you say that (again)
I think the remotes will be coded to that relay,
as it is basically the central locking ECU,

so it will need to have the remotes coded to the new one.

[1I1]

Stink thing with these Camrys is that to code in a remote you need either a current working one or we can get pre-programmed ones in from Toyota NZ that just need to be finaised... but to get one of those a chassis number from the car that relay came from is needed.

[Mr Ree]

It has the docking station in the glovebox, and I recall reading in the car manual that it can be reprogrammed.

Infact, one day when I was bored, I docked it in there and went through the procedure just to see it function.

I have two remotes which both function too.

Mark, what would a customer in my situation order, to get it functional again? Is the integration relay absolutely 100% vehicle specific, or just a general part with an identical part number to any other camry?

Thanks again for your help

[Mr Ree]

Update...

I just picked up my car from the panel beaters, and pulled out my keyring fob, docked it in the docking station in the glovebox and followed the Toyota procedure for how to program it, but no dice.

The LED didnt flash at all, which means the integration relay isnt talking to the remote.

I almost got excited this morning, thinking that I might have forgotten to try this years ago lol...

[Mr Ree]

Here are a few pics of the unit, and a close up of the burned out component on the PCB.

[sergei]

It is a relay, why not swap from the "good" unit into the one you have?

[Mr Ree]

Thanks for your input, Sergei.

I dont think my soldering iron is anywhere near delicate enough for the job, given its tip size.

Does anyone from the 04 know who in Wellington would be good to take both units to, to have the melted relay replaced?

Thanks

[Stott69]

I take it its the black box behind the red cap's that needs replacing? Whats it like on the underside?

[Mr Ree]

There is a noticeable discolouration of the solder on one of the relay pins, where it joins the trace. Apart from that, it appears normal.

Ill take a pic in the morning and post it up too

Send both units to me (with return courier package), I'll do it for fun .

It looks like double sided board with huge pin spacing on the relays (and not those multilayer boards that are very difficult to work on). It is relatively easy...

[Mr Ree]

Thanks alot for you offer to help with this, Sergei

Unfortunately, If I send both units to you, I suspect my car will not operate.

I will have to unplug the other unit from the car tomorrow and see if everything still functions, and then update you.

Thanks:)
