P0949

2017-10-10

Description:

  • The fault code P0949 indicates that the adaptive learning process for the automatic shift manual mode has not been completed. This process involves the transmission control module (TCM) adapting to the driver's shifting patterns and optimizing the shifting performance. When the adaptive learning is not complete, it may result in less efficient or inconsistent shifting.

Possible Symptoms:

  • Check Engine Light illuminated

  • Abnormal or inconsistent shifting behavior in automatic shift manual mode

  • Reduced performance or efficiency in automatic shift manual mode

  • Transmission may hesitate or have difficulty shifting smoothly

Possible Causes:

  • Interrupted or incomplete adaptive learning process

  • Faulty transmission control module (TCM)

  • Wiring or connection issues in the transmission control circuit

  • Low battery voltage or power supply issues

Related Parts:

  • Auto Shift:

Possible Solutions:

  • Ensure that the adaptive learning process is allowed to complete by driving the vehicle under various driving conditions and shifting patterns.

  • If the adaptive learning process does not complete after driving the vehicle for a sufficient amount of time, it may be necessary to diagnose and address any underlying issues.

  • Check the wiring and connections in the transmission control circuit for any signs of damage, corrosion, or loose connections.

  • Test the battery voltage and power supply to ensure they are within the proper range.

  • If necessary, consult a professional mechanic or dealership for further diagnosis and repair.
