P287C — Transmission Adaptive Values Not Learned

About P287C

P287C is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P287C is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The Powertrain Control Module (PCM) or Transmission Control Module (TCM) monitors the status of transmission adaptive learning, which compensates for clutch wear and hydraulic characteristics to ensure correct shift quality. DTC P287C is set when the control module determines that the required adaptive values have not been successfully learned or stored after a calibrated number of drive cycles, shift events, or completion of a learning routine. This typically occurs when learning conditions are not met or adaptive learning is inhibited by another fault. When this code is set the transmission ...
