Hi there,
It looks like you ran into some complications replacing your stereo, and somehow the anti-theft theft system was activated all of a sudden. If you see error codes U1000, U1234, and U1327, the "service anti-theft" warning indicates communication issues within your vehicle's computer network connections. Check these details about the error codes:
1. U1000: Bus fault issue. Data is not being received from one or more modules on the network.
2. U1234: This code is somehow specific to Ford and relates to lost communication with the CAN (Controller Area Network) module. The CAN module is crucial for communication between various electronic components in the vehicle.
3. U1327: It is related to lost communication with the anti-theft control module (PATS)
Possible causes:
1. Wiring issues. Check for loose connections or some shorted or grounded wires.
2. Faulty stereo installation. Possible incompatible aftermarket stereo component using a different wiring configuration.
3. Security system fault. The "service anti-theft message" points towards an issue with the vehicle's anti-theft system. You can try to disconnect the battery (remove the negative battery terminal for 3 minutes) again to reset it.
Still, it is best to have your vehicle be diagnosed and troubleshooted by a certified mechanic, or your trusted local auto repair shop. I hope this helps!
