Check the battery connections and ensure they are clean and tightly secured. Also, inspect the main fuses and relays related to the CAS3 control unit for any signs of damage or corrosion. Let me know how it goes or if you have further questions!
The sashes and relays and contacts are all okay!

Inspect the ground connections, especially the one from the battery to the chassis and engine block. A poor ground connection can cause electrical issues. If the problem persists, it might be worth checking the ignition switch or consulting a professional. Let me know if you need more help!

Check the wiring harness for any signs of damage or disconnection between the battery and the CAS3 unit. Pay special attention to any connectors or junction points that might be loose or corroded. If you're still having trouble, it might be best to have a professional diagnose the issue. Let me know if you have any further questions!
