How Do you reset the Control CRT on 88 Buick Reatta?

To reset the Control CRT (Centralized Relay Technology) on a 1988 Buick Reatta, first disconnect the vehicle's battery, allowing it to sit for about 10-15 minutes to clear any stored faults. Reconnect the battery and turn the ignition to the "ON" position without starting the engine, allowing the CRT to initialize. Finally, start the engine and check to see if the CRT operates normally. If issues persist, further diagnosis may be needed.
