How to Diagnose and Solve B1601 PATS Received Incorrect Key-Code From Ignition Key Transponder Issues
Introduction
If you own a Ford vehicle, you may have come across the B1601 error code. This code indicates that the Passive Anti-Theft System (PATS) has received an incorrect key-code from the ignition key transponder. This can be a frustrating issue, but with the right knowledge and tools, you can diagnose and solve the problem yourself. In this article, we will guide you through the process of diagnosing and solving B1601 PATS issues.
What is the PATS System?
The PATS system is a security feature in Ford vehicles that prevents unauthorized access to the vehicle. It works by using a transponder in the ignition key that communicates with the vehicle’s computer. If the computer does not receive the correct code from the transponder, it will not allow the vehicle to start.
Diagnosing B1601 PATS Issues
The first step in diagnosing B1601 PATS issues is to check the ignition key. Make sure that the key is the correct one for your vehicle and that it is not damaged or worn. If the key is damaged or worn, it may not be communicating with the transponder correctly.
Next, check the battery in the key fob. If the battery is dead or low, it may not be able to communicate with the transponder. Replace the battery and try again.
If the key and battery are both in good condition, the next step is to check the transponder ring around the ignition switch. This ring is responsible for communicating with the transponder in the key. Make sure that the ring is clean and free of debris. If it is dirty, clean it with a soft cloth and try again.
If the transponder ring is clean and the key and battery are in good condition, the issue may be with the transponder itself. In this case, you will need to take your vehicle to a qualified mechanic or dealership to have the transponder replaced.
Solving B1601 PATS Issues
If you have determined that the issue is with the transponder, you will need to have it replaced. This can be done by a qualified mechanic or dealership. Once the transponder has been replaced, you will need to program it to your vehicle’s computer.
To program the new transponder, you will need to have two working keys for your vehicle. Insert one of the working keys into the ignition and turn it to the “on” position. Wait for the security light on the dashboard to turn off, then remove the key.
Insert the second working key and turn it to the “on” position. Wait for the security light to turn off, then remove the key.
Finally, insert the new transponder key and turn it to the “on” position. Wait for the security light to turn off, then remove the key. The new transponder key should now be programmed to your vehicle’s computer.
Conclusion
B1601 PATS issues can be frustrating, but with the right knowledge and tools, you can diagnose and solve the problem yourself. Remember to check the ignition key, battery, and transponder ring before taking your vehicle to a mechanic or dealership. If the issue is with the transponder, have it replaced and programmed to your vehicle’s computer.
