I recevied a Limited Service Campaign letter in the mail today from Toyota stating there is a risk to the AIP with the current ECM configuration under certain driving conditions. There are no details about the update other than it reduces the possibility of failure. I have read about some AIP issues with the 2012 models with the 5.7 engine. I have not had any issues with mine, but will probably get the ECM update. Evidently there have been enough issues to warrant this update. Hopefully the folk at the dealer can shed a little more light on this update, but I am skeptical.

Yeah I took mine in last week, they told me it was a Air fuel ratio update for the AIP and I watched him do the update on my 2012 and I can tell you that I did see a lot more throttle response and maybe an increase in fuel economy.

The update said it was for 2012 and 2013 yr models, so not sure.

I just bought a 2013 CM RW and was wondering if this would apply to mine. I just called the service department at the dealer I purchased it from, and they are not pulling up any recall/tsb that needs to be performed on my vehicle.

Thanks.

Did you register your truck (and yourself) at the Toyota website? Here: Toyota Owners Official Web Site: Service Coupons, Owner's Manuals, Service Scheduling And More (http://www.toyota.com/owners/web/pages/home)

I did when I bought my 2013 Tundra - and when I log in - it says my truck is subject to the recall.

Thanks for the quick response. Looks like mine is not subject to the recall. Maybe Toyota already updated mine before it left the factory?

I spoke with the service adviser about this and he said the update reduces the duration the AIP runs to prevent moisture accumulation which is known to cause them to fail in certain situations puting the engine in a limping mode. There are a lot of threads on AIP issues in this forum and supposedly they were "improved" for the later models. Evidently whatever "new" design was incorporated in these later model Tundras was not enough to resolve the issue. Just my 2 cents.

First thing I felt, after recall service, was better throttle response. I don't know why but it did.

From what I have been reading on this issue, the problems with the AIP that are addressed in the Service Campaign seem to be mostly in the Northern cold climates. Toyota is re-flashing the ECU on the affected trucks, but I have not heard of anyone in the South that has had this issue so far. I had mine done anyway to be safe. Time will tell.

I just had my ECM update done this past Saturday morning along with my 5000 mile service on my 2013 DC 4WD. As soon as I got up to speed I seemed to notice the transmission shifting up and down more? It seems od but it seems to shift a little harder also. It is rather irritating, if I am going down a hill and slowing down from around 50 or so I can physically feel it shift and jerk into a lower gear. My wife has been driving Honda/Acura cars for years and they do the same thing. This is one thing I have always hated.... now my Tundra is doing it. Anyone else see/feel similar changes after the ECM Update?

To ad insult to the whole thing I got my truck back home and found a big gouge in my drivers door. I just washed my truck the day before taking it to the dealer and I'm 98% sure it was not there. To be even more sure it wasn't there I had my last truck for 13 years and was always careful with it, In 13 years it never got a ding like this. I don't see me being this careless after only 6 months of having my first brand new truck?

Ouch! Whose the potentially crummy dealer?
