Question about 2001 Cadillac Catera
Security Code (Theft-Deterrent) required or Fuse blow. Recently unplugged the battery? or any work in there?
THEFTLOCK is designed to discourage theft of your radio. Your vehicle has a “built-in” theft-deterrent feature on each radio that is automatic -- there is no programming required. The radio in your vehicle cannot be used in any other vehicle. When the radio was originally installed in your vehicle at the factory, it stored the Vehicle Identification Number (VIN).
Each time the ignition is turned on, the VIN is verified. If the vehicle’s VIN does not match the VIN stored in the radio, THEFTLOCK will be activated and the audio system will not play. If the radio is removed from your vehicle, the original VIN in the radio can be used to trace the radio back to your vehicle.

Instrument Panel Fuse Block (driver's side)
I suggest check in your Catera Owners Manual the FUSES position 6 and 26 for RADIO.
Also, other experts comment that, when servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.
Condition / Concern:
Radio inoperative with key on, auto door lock feature disabled, a/c compressor does not engage and DTC U1255 stored in the radio. Radio may work in rap or accessory until the door is opened.
Recommendation / Instructions:
Cause: Clamp 15A, fuse #10, 10 amp fuse blown to the BCM/PZM, terminal A11. This fuse is normally powered in run and not during cranking. When this fuse is blown, the BCM acts as though it is in the crank mode with the key on. The BCM turns the radio off via CLASS 2 and inhibits auto door lock operation. The HVAC control head inhibits a/c compressor operation.
1. Replace the 10AMP #10 fuse.
2. Check the heater water pump located at the right wheel well area for a leak. Also, check the auxiliary pump located on the left side of the radiator support for a leak. If either pump is leaking, coolant may be dripping onto a connector for this fused circuit which may cause a short to ground condition.
3. If both pumps are okay, install in-line fuses rated less then the fuse in question for each component affected to isolate the failed circuit.
