The Godiag CAS4/CAS4+ Test Platform is a valuable tool for automotive locksmiths and technicians working with BMW vehicles. It allows for quick and efficient testing of CAS4 and CAS4+ immobilizer systems. However, occasionally users encounter issues, such as the test platform coil not working correctly. This guide will outline the steps to test a synchronized and unsynchronized key, troubleshoot potential problems, and offer solutions for a non-functional coil.
Testing Key Synchronization with Godiag CAS4 Test Platform
Before troubleshooting a potential coil issue, it’s crucial to understand how to properly test key synchronization using the Godiag CAS4/CAS4+ Test Platform. Here’s a step-by-step guide:
-
Connect the Test Platform: Connect the Godiag CAS4/CAS4+ Test Platform to the CAS4/CAS4+ module using the provided power and engine connectors. Ensure the connectors are securely fastened.
-
Connect the Converter Cable: Attach the Godiag converter cable to the designated port on the test platform.
-
Secure the Test Platform: Tighten the screws on the test platform to ensure a stable connection.
-
Power On: Connect the power adapter. The power and immobilizer indicators should flash, indicating the platform is powered on.
-
Power Button Functionality: The power button controls the platform’s operation:
- First Press: Starts the platform. If the key is synchronized, the “DASH” indicator will illuminate continuously.
- Second Press: Turns off the platform.
- Third Press (If Applicable): If the CAS4 module isn’t communicating, pressing the button a third time might re-establish communication. This could indicate a coil issue.
- Fourth Press (If Applicable): Turns the platform back on.
Troubleshooting an Unsynchronized Key and Potential Coil Issues
If the key is not synchronized, the “DASH” indicator will not illuminate continuously. Here’s how to identify a potential coil problem:
-
Unsynchronized Key Test: Place the key into the test platform’s coil. Observe the “DASH” indicator. If it doesn’t flash, it suggests a communication problem.
-
Power Button Test with Unsynchronized Key: Press the power button. If the “DASH” indicator briefly illuminates and then turns off, it confirms a lack of communication between the key and the CAS4 module. This often points to a faulty coil or a connection issue within the coil circuit.
