Hi to all!
I have a '99 Camaro 3800 and I want to replace the Body Control Module with a new one.

The BCM part code that have is #0953681 and it is without the remote and without thief lock.

I have two ways: replace with the same BCM without remote and set only the VATS code at the first start, or replace with the BCM that have the remote (part #0953691), buy the remotes and program it in a GM dealer, but I 'dont know if thief lock likes it.
My Camaro don't have thief lock and I think dont have the thief deterrent relay, so sombady knows if it works without?

So somebody have do these change of BCM to have the remotes?
I need to be sure that these bcm works.

It works better?

thanks boyz!

The resistor in your key needs to match the body control module otherwise the car will not start.

Keyless entry is not affected by changing the body control module. All 97-02 foodies have the same Keyless remote.

Your key to start the car has a black chip on it, correct? That is the vehicle anti theft


Why do you "want" to replace your body control module.

Volcente

Thanks for your answer!

I want to replace the bcm because I have an intermittant work of both lock switch.
The vats code on my ignition key is not a problem because it will set at the fist start with the new bcm.
I have the VATS code on the key but I dont'have the remotes.

My actually BCM don'have the remote (AU0) and dont'have the anti-thief (UA06).
the bcm with remotes have an alarm when the doors are close by remote that sounds hazard and i dont'have it so I dont'know if a different bcm will work.

Maybe the alarm sounds as it prefer? I dont know.

I need to know if i buy new the bcm with remote and with anti-thief it will work good.

Is this a European-delivery car?

Volcente

Yes.
My Camaro is a European Export Version and some things are different.
I write from Italy.

I think I understand what you are asking.

If your camaro has power locks and power windows the body control module is ready to be programmed to a new keyless remote. If your car is original with manual windows and no locks, many things must be re wired.

The factory alarm is able to honk with arming, or flash lights, or both. It is not a very good alarm

Volcente

I have the power locks (that works intermittant an for this i change the bcm) and i have the power windows.

I dont'know if the factory alarm likes to not be complete and let the new bcm works perfect.

Maybe the car start the alarm starts as it prefer because I dont have the relay or other components, so I need to know if a person have really do this bcm change and are sure that it works without alarm.

I have to think that this is a very expensive part to buy in Italy!!!

Have you considered doing the free fix for this problem? Have you looked at the FAQ section and read the threads about the BCM fix? It sounds like you may have the common problem with the solder:

(Also Known As: BCM FIX)

(Pic of affected solder in Post #22 of second thread.)

Volcente

Maybe 450€.

But the question is another if someone of you have try to change the bcm and use the remote without have the theft deterrent/alarm system.

But now I think that the answer is in the 1999 Camaro user guide:

To match the remotes at the first point said:
1. Turn the ignition key to RUN, then to OFF. This will
disarm the Content TheftDeterrent/Alarm System(if your vehicle has this option).

The body control module IS the factory alarm

I do not understand your question.

You could ADD an aftermarket alarm to control the door locks, but the body control module is the factory alarm system.

Volcente

The new BCM works only if i sets the VATS code like the stock bcm?

If i don 't have the alarm or the remote it will work normally as a stock bcm without the remote/alarm reciver?

the bcm #0953691 have anti-thief (UA06) and my car was born without it.
if i put this new bcm inside it will work normally or the ua06 give me some problem?

I want to know it from a person that have do it.

On your driver's side door there should be a bunch of stickers. One of the stickers will have lots of numbers.



For us spec vehicles there are only two options, the car came with keyless entry which ment it came with the remote and antitheft, or it had manual locks and no remote or alarm


I am not aware if the car needs the alarm to function the body control module. To my knowledge the only physical piece of the alarm is the shock sensor in the trunk cargo area behind the right rear speaker

Replying again I see your question

I do not believe your 09353681 control module will work on a car that was original with 09353691 module

The 09353681 will not be able to control your power windows or locks

Volcente

My friend sorry for my english but I dont explain well.

Now inside my CAMARO there is 09353681 bcm,this is the original bcm, and I want to put a REMAN BCM 09353691 that support remotes and have anti-theft.

I want to know if it works if i dont use the anti theft... i dont have shock sensor for example.

this is the question.

I can not directly say.

If your car did not come with optional alarm, I believe it still came with the harness to plug one in. So you should be able to use that module without any problems

The best information I can find about what is needed to run the vehicle is found in this link. The original thread creator is removing wires from his race car and is trying to find what body control wires he needs to keep on his car, so that that car will still run

What I'm not sure of, does the key for your car, when it was new, does it have a chip in the key?

If your original does not have a chip you would need to have a new key made, and a new ignition cylinder, to install a new antitheft chip ignition key to start the car


Second pin info on the body control module


Pin number C11 is what confuses me. It says starter relay (domestic only)

Volcente

I have an 1999 export Model for Europe

I have the VATS code on the ignition key, I have the power locks and i have the power windows.

What's up everybody, I'm Edoardo, a friend of Volcente...same V6 Camaro, MY 1998, European export vehicle sold and registered in Italy.

So, I've noticed that you guys don't refer to cars with power locks BUT without the remote control...well, our cars work like that, we don't even have power trunk release. Answering a question asked before, our ignition keys are PasskeyII type, and this is the only antitheft measure in our cars, no alarms, nothing, just the key acting as the immobilizer.

My friend here can't explain himself really well, so I ask this question for him and for me because he want to fit the #09353691 module instead of the original #09353681:

we don't know if we have antitheft relay and other relay behind the glove box, such as the trunk release relay, but I'm sure we have at least a preset (cables, connectors and such),so will the #09353691 module work if we do not have any of these relays around? Or maybe the key and the built-in alarm are two separate things, so as long as the BCM recognize the ignition key there'll be no problem at all, even if we don't want accessories like alarm or the remote control? We're concerned because on European cars this "technology" will interfere with the car itself, causing severe malfunction.

I hope I'm explaining myself better than my fella...thanks in advance for any reply! Ciao!

The vehicle alarm system is separate from the vehicle pass key. The vehicle alarm will not interfere with any vehicle operations
The alarm only functions to sound the horn and flash the vehicles lights when the door is opened without using a keyless entry remote if the alarm is set to active. To disable the alarm my factory owners manual states "once the vehicles key is placed into the igniton and placed into the run position the alarm will turn off if it has been activated.

Correct. It appears you can disable the alarm functions completely by following this procedure in the owners manual

The alarms only purpose is to flash the lights and sound the horn.

I see no reason why the vehicle would have any problems with the alarm body control module.

Many many many of these camaros and trans ams function properly with the alarm system body control module, with all of the alarm components removed from the vehicle

EBLC

Well, we were concerned because, like I was saying, our crappy European cars ignition and alarm systems DO "talk" with each other, acting as a coupled inseparable immobilizer.

Now you answered all our questions and made clear a lot of things, so we're absolutely good! Thank you for your reply and crystal clear explanations, appreciate it!
