No, you can not disable the Passlock system. Cutting wires will serve to disable your car only.
As you were told, this system is integrated right into the operating system and unless the computer receives the correct Passcode, it will not energize the fuel injecters.
As I posted earlier, you can shut off the contents security but not the immobilizer.
I can give you a way to bypass the sensor in the ignition switch, but that is only one component of the system and the rest of it will be active. You will just be fooling it into thinking it received the correct passcode.
Here is how that is done.
Here’s how you can bypass the sensor.
Go buy a 2.2k (2200 ohm) ohm resistor at an electronics store. Go to radio shack and just get one as close to that as you can. Remove the covers on the steering column and locate three small wires at the lock cylinder. Cut the yellow wire and the orange/black wire. Solder the resistor between those wires. Tape it up and put the covers back on and follow this relearn procedure. If this doesn't work you have a wiring problem in the steering column.
- Turn ON the ignition, with the engine OFF.
- Attempt to start the engine, then release the key to ON (vehicle will not start).
- Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF.
- Turn OFF the ignition, and wait 5 seconds.
- Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes ( the vehicle is now ready to relearn the Passlock™ Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK).
The vehicle learns the Passlock™ Sensor Data Code and/or password ***** the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
- Start the engine (the vehicle has now learned the Passlock™ Sensor Data Code and/or password).
- With a scan tool, clear any DTCs if desired (history DTCs will self clear after 100 ignition cycles).
