Here is the aforementioned TSB. I always review TSB's thoroughly. I always make it a point to try whenever possible to get the TSB from the manufacturers website as well. Reason for this is they have the latest information. Maybe, there was a change in procedure, etc. Using the manufacturers website information assures me of the latest and greatest information. I also scan the vehicle as well with my tooling. It is not that I do not trust my customers. It is just assurance that we are going in the right direction. It also gives me an opportunity to see if we have other issues.
It is the old calibration that needs updating. Normally, I use Toyota Techstream to program. This shop had sketchy internet and the calibration I needed I had on a Toyota Calibration CD. Toyota no longer uses Calibration CD's. Like most manufacturers it is all web driven. I will have to get out my J2534 reprogramming equipment. I am not a big fan of J2534 programming. I like to use factory tooling. In this case I felt confident using it.
I always check if the calibration was really updated.
