Mazda CX-5 Transmission in Emergency Mode - TCM Error

Hello dear community, My name is Hartmut and I have a problem with my Mazda CX-5, model year 2017, diesel, with 169,000 km mileage. The vehicle sporadically goes into limp mode and the error 'TCM faulty' is displayed in the fault memory. Does anyone know this problem and can tell me more about it? I would be grateful for any help. Best regards, Hartmut.

Check the transmission fluid level and condition first, as low or dirty fluid can cause transmission issues. If the fluid is fine, consider having the TCM connections inspected for any loose or corroded contacts. Let me know how it goes or if you have further questions!

Thank you for the quick reply. The transmission had a transmission flush and new oil only 1 year ago. I will have the connections on the TCM checked.

Make sure to also inspect the wiring harness for any signs of damage or wear. If the issue persists after checking the connections, it might be necessary to have the TCM itself tested or reprogrammed. Keep me updated on your progress or if you have any other questions!
