Bulletins for this model year that name P287C
ATS1511012022-05-09. 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.
ATS-151101 V22021-05-14. 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.
