Toyota Communication Module Activation Failed

If you’re getting the message “Toyota Communication Module Activation Failed” it means that there’s a problem with the JCI (Joy Communications Interface) in your Toyota. This is the system that allows your car to communicate with the dealer and other service providers. There are a few things that can cause this error, but the most common is a bad connection between the JCI and the car’s computer.

If this is the case, you’ll need to have the JCI replaced.

If you’ve ever had a “check engine” light come on in your Toyota, it’s likely because the Toyota Communication Module (TCM) has failed. The TCM is responsible for communicating with the car’s onboard computer, and when it fails, the check engine light will come on. There are a few things that can cause the TCM to fail, but the most common is simply age.

Over time, the solder that holds the chips in place can crack and break, causing a loss of connection. If you have an older Toyota, it’s probably time to start shopping for a new TCM.
