Hey folks, I noticed a few of you have been asking about the KWP2000 code. This one’s a little different because KWP2000 isn’t exactly an error code like P-codes; it’s a communication protocol used by your car’s ECU to send data to diagnostic tools. So, if you’re seeing this, it’s likely because of a connection issue during a scan.

Here’s what you can do:

1. Check your diagnostic tool - Sometimes, cheaper scan tools won’t work properly with the KWP2000 protocol, especially on older Fords.
   
2. Look for loose connections - Double-check the OBD2 connector and make sure there’s nothing blocking the connection.
   
3. Reset the ECU - Sometimes, just resetting the ECU can clear out minor communication issues.
   
4. Update your software - If your scan tool has an update option, try updating it to ensure it’s compatible.
   

This one is more about how you’re getting the code rather than an actual car issue. If you’re having trouble connecting your scan tool, follow these steps and see if it helps!
