P287CTransmission Adaptive Values Not Learned
- Generic OBD-II code · Powertrain
- Can trigger limp mode
- How the car detects it
- P287C means the transmission controller finds its trim or adaptation data missing, invalid or unfinished. GM's 2023 Corvette dual-clutch TCM runs the check at initialisation, covering end-of-line and online values such as clutch preload, kiss point, fill volume, rod and parking lock positions, and learn routines left incomplete; the code is Type C, without MIL. Honda and Acura describe a trap on the 9-speed automatic of the 2015-16 TLX, 2016 MDX and 2016 Pilot: a replacement TCM arrives without trim data, sets P287C at each ignition cycle and then refuses the teach-in; clearing the code without cycling the key lets the procedure run. Mercedes lists P287C00 for the 8G-DCT as an unfinished first start-up of the transmission unit, and Ford's TR9070 summary as a learn data fault.
