To clear codes on a 1991 Cadillac Eldorado, first, disconnect the negative battery terminal for about 10-15 minutes. This will reset the vehicle's computer and clear any stored trouble codes. After reconnecting the battery, you can start the car to ensure the codes have been cleared. Alternatively, you can use an OBD-I scanner to erase the codes directly if you have access to one.

To reset the computer on a 1991 Cadillac Eldorado, disconnect the negative battery cable for about 10-15 minutes. This will clear the computer's memory and reset any stored trouble codes. After reattaching the cable, start the vehicle and allow it to idle for a few minutes to let the computer recalibrate. Lastly, drive the car gently for a short distance to help the system adapt to normal operating conditions.
