Hello Aziners,
I am getting new seats installed in my 08 TL Type S and was wondering if there is any precautions or steps I should take when installing the seats? I know that SRS airbag light can come on and was wondering is there any way to avoid it or reset on my own if it does come on?

P.S. seats are from a fellow Aziner and like new and his vehicle was never in a accident.

you should probably unplug the car battery when doing this just to be safe

Yes and let the airbag system discharge before unplugging anything, but my question is will there be an issue swapping in seats from a different Type S? Will the airbag light come on?

Ask JHH for more detail but be ready for that light to come on the only way to turn that light off if you have hds.

The Light should only come on if the ignition is on when you have a SIR wire disconnected. So make sure your connectors are together before you turn the key. You can disconnect your battery IF you would like, I work at a dealer and ive never done it here. The module stores back up battery power incase the battery voltage is disconnected during a crash event. The module reads the resistance of the air bag, so if its connected and the wires/bag are good, then you should be ok. Easy man, just get it done!

OK so I should wait for the airbags to discharge after I disconnect the battery??

NBP_BALLER

The airbags do not have a charge in them, the Airbag module itself does. Now each airbag is considered a module but thats not what im talking about. The main module has an internal battery. It may last up to 5 minutes after the battery is disconnected. You can disconnect it it you want or not. Its not going to affect anything, just dont turn the key on(this will set a code instantly) until the new seats are in and connectors are together. The air bags will not blow or anything like that so dont worry. They have to have 12v sent by the module to blow them. I get to blow them up when i take them out at work

I understand what you are saying MBP_baller but JJH had a different experience. He too disconnected the battery and swapped the opds unit but still got the srs light on BOTH cars

NBP_BALLER

Hmm... sounds a bit funny to me. Anything is possible though. Did he just go in and clean the codes? The module resistance may need to be relearned. A possibility I guess. Never ran into this issue.

i'll show him this thread and hope he chimes in with more info

Nothing in here was mentioned about the OPDS module so I'll go ahead and fill you in OP about that first off.

Each car has an OPDS module (Occupant Position Detection System) that is synced individually to a cars ECU. Because of this, one of two must happen.

1) You must swap this module so that your car retains the original module

2) The module must be synced with your ECU with an HDS/HIM tool.

The second option is the less favorable because you're going to have to pay the dealership for an hour of labor to have them do this.

Here's where the OPDS is located.

JJH

Just make sure that you give the internal SRS battery enough time to discharge before unplugging anything or else you will throw a light that you will either have to buy an HDS tool to reset or have the dealership do for you.

I would recommend the former since you can get an HDS tool for about the price of 1 hour of labor and the latest software can be rented for $10/day.

This explains the process you have to go through to program the OPDS module.

Where do I get a compatible HDS unit?

godfather18

iTrader: (1)

Also does that module have to be transferred over I can't use the one that comes with the new seat and reprogram that one?

godfather18

iTrader: (1)

Ok so the airbag light came on like was mentioned and now I'm deciding if I should have the dealer reset it or get this HDS from amazon JJH can u let me know if this will work?

Did you switch the modules ^ ?

godfather18

iTrader: (1)

No do I really have to? Is it necessary? If It is how do I take the back off the seat to get to it.

JJH

iTrader: (1)

Did you read my posts above?

Reread my posts. Yes, it's necessary. Unless you want to pay the dealership to resync the OPDS module. Lots of labor.

godfather18

iTrader: (1)

Ok so how do I get to that module inside the seat?

Ok left side of seat and how do u open the back?

JJH

iTrader: (1)

There are two clips on the bottom of the seat. Pull the bottom of the seat towards the back of the car. Then you will slide the back of the seat up towards the ceiling. After doing this, you will spread apart metal clips on the left side of the seat and be able to reach in and unscrew it, unplug it, and remove it. Swap with module from your original seat.

U think the light will turn off when I switch the modules?

JJH

iTrader: (1)

No, once the light is on it stays on until an HDS tool is used to reset it.

Your airbags also won't deploy in an accident if the light is on as the SRS system is disabled.

What's a good HDS unit that will work for our car.

NBP_BALLER

This is very helpful information to OP. I was not aware of honda/acura specific srs systems. I work for GM, Cadillac specifically and there are no gm cars with a module like this. Automakers were instructed to put an OPS(occupant position sensor) in every car to tell whether a child or adult is sitting in the car. GM cars use a magnet/sensor on the seat track to determine how far the seat is forward/reverse and a silicon cushion on top of the seat foam underneath the seat cover which detects pressure as well as a sensor on the seat buckle itself. These all are wired specifically to the main SRS inflatable and restraint module, as well as the seat belt pre-tensioner and the side airbag in the seat. We can swap seats all day long and have no issues, as long as the connectors are re-connected. If the ignition is on and one is disconnected, the code will not go away until a GM Tech2 is used. Its looks like the Acura system is called OPDS. Learn something new everyday! Looks like these boys got you covered though. Find a friend that works for honda/acura and get it done for free! Thats what I would do, or call your dealer and tell them you need a code cleared. No dtc scan or diag, they will prob do it for free.

so since his light is alrdy on, theres no real point in swapping it right? since the only way to get rid of the light is to reset it.

or is there some other benefit to still swapping them?

JJH

iTrader: (1)

Yes, there is still a benefit to swapping them. If he swaps them, the dealership won't have to go through the syncing process of assigning the new OPDS module to his cars ECU. Either way, the SRS codes will need to be cleared in order for the system to function correctly. He's just going to be paying less labor (and I think that dealerships have a fixed cost of $1xx for syncing OPDS modules).

As far as what OPDS module to get, you'll have to message the sellers and ask what version software they are running. You have to get below version 2.26. After version 2.26 Honda implemented a call to home function that connects to the Honda "mothership" to check for authenticity.

NBP_BALLER

Yeah I would swap the modules, then just clear the code. They will def charge you to reprogram it. They might not charge you anything to clear the code though. I have been asked to do it on occasion. Who knows, give them a call and tell them you disconnected it and now your airbag light is on. You know nothing is wrong and just need the code cleared. They dont really have any labor into it to clear it. Just a few minutes, thats how they keep a good rep.

godfather18

iTrader: (1)

Ok I swapped modules and now I have to get the light reset.

JJH

iTrader: (1)

Good. Call some local mechanics and see if any of them have an HDS tool or the ability to reset an SRS light.

godfather18

iTrader: (1)

Thats cheaper than paying the dealer right or can I just buy a inexpensive HDS?

paperboy42190

iTrader: (7)

for only 1 car, might be cheaper and easier to just go to dealer
