Service bulletin B15054
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
| BTS-151101 V2 | 2021-05-14. Service bulletin. Replacement TCMs don’t come with trim data. After installation, you need to run a teach-in (hydraulic pressure characteristic calibration) procedure with the HDS. The problem is that A/T DTC P287C (transmission adaptive values not learned) is set, which prevents teach-in. This happens because the TCM is programmed to look for trim data any time the ignition is cycled. If the TCM doesn’t see that trim data, it sets A/T DTC P287C. If any DTCs are set, the TCM won’t initiate teach-in and, as a result, can’t learn the trim data. It’s a classic catch-22 situation. |
