The P1779 fault code is related to the transmission system in your automobile. It occurs when the Automatic Transmission Control Module (TCM) receives incorrect or invalid information from the Engine Control Module (ECM) through serial data communication.

This faulty transmission-related information triggers the TCM to set the P1779 code, indicating a problem with the engine torque delivered to the TCM signal. When this fault code is triggered, it is important to address it promptly to ensure the proper functioning of your transmission system.

Ignoring or delaying the necessary repairs can lead to further damage and potentially more expensive repairs down the line.

It is recommended to consult a qualified mechanic or technician who can diagnose the exact cause of the issue and provide the appropriate solution to resolve the P1779 fault code.

What are the possible causes of the automobile fault code P1779 and how can I check for them?

If you’re seeing the fault code P1779 and your engine light is on, there are a few possible causes to check for. First, make sure to check any other engine-related codes that may be present. The fault could be due to a faulty Engine Control Module (ECM) or a problem with the ECM harness, such as an open or shorted circuit. It’s also worth checking the electrical connections to the ECM to ensure they’re secure. Another potential culprit could be a faulty Transmission Control Module (TCM). To fix the issue, start by visually inspecting the wiring harness and connectors. Look for any signs of damage or corrosion, and check for any broken, bent, pushed out, or corroded pins in the connectors.

How can I visually inspect the wiring harness and connectors to fix the P1779 fault code?
