DTC P287C: Transmission Adaptive Values Not Learned (DCT)

General Description

The powertrain control module (PCM) absorbs variability of each vehicle, and to control smoothly on switching forward/reverse, starting, and automatic shifting, the valve body characteristics and shift position are learned and corrected at the factory. At the factory, shift position learning which shift fork position sensor is used, and valve body learning are done, and records to the PCM that the learning procedure were successfully done. Learnings and corrections must be done if transmission or PCM is replaced. When the learning procedure is not finished when the PCM is activated, the PCM detects a malfunction and stores a DTC.

Monitor Execution, Sequence, Duration, DTC Type, OBD Status

OBD Status	PASSED/FAILED/NOT COMPLETED (STILL TESTING)

Enable Conditions

Condition
State of the engine	Running

Malfunction Threshold

The valve body characteristic learning procedure and the stroke sensor learning procedure are not finished when the PCM is activated.

Possible Cause

NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.

Transmission control system not learned
PCM internal failure

Confirmation Procedure

Operating Condition

Start the engine.
2.
Shift to P position/mode, and wait for at least 3 minutes.

With the HDS

None.

Diagnosis Details

Conditions for setting the DTC

When a malfunction is detected, the A/T gear position indicator blinks and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory. The MIL does not come on.

Conditions for clearing the DTC

The A/T gear position indicator comes off by turning the vehicle to the OFF (LOCK) mode. The Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the 12 volt battery.
