Internal Transmission Control Module Monitoring Level 2 Error, Calculation Shift By Wire
This code means that the car's computer is having trouble communicating with the part that controls shifting gears in the transmission. It's like if your remote control stopped talking to your TV.
The transmission control module (TCM) is responsible for managing gear shifts in a vehicle. A P1714 code indicates that the TCM has detected an error in the shift-by-wire system, which electronically controls gear changes.
The P1714 code is triggered when the transmission control module (TCM) identifies a fault in the shift-by-wire system's internal monitoring. This system uses electronic signals to control gear shifts instead of traditional mechanical linkages. A level 2 error suggests a significant deviation from expected operation, potentially affecting the vehicle's ability to shift gears properly.

Transmission Control System Issue
• Avoid driving the vehicle until repaired
• Consult a professional mechanic
• Keep a record of any recurring issues
Transmission components may be covered under powertrain warranty. Check with the manufacturer.
The P1714 code has been reported in vehicles with electronic shift controls, particularly in models with advanced transmission systems.
High – This issue can affect vehicle drivability and should be addressed promptly.
Driving with a faulty transmission control system can be unsafe. Address the issue to ensure compliance with safety standards.
• Vehicle must be in a safe, stationary position
• Ensure the ignition is in the 'on' position without starting the engine
The transmission control module is typically located within the transmission housing or nearby in the engine bay.
Q: Can I drive with a P1714 code?
A: It's not recommended, as it may cause further damage or unsafe driving conditions.
Q: How do I reset the TCM?
A: A professional mechanic can reset the TCM using specialized diagnostic tools.
