If you cut the signal wire(yellow) and then bare a section of the low ref wire(black/orange) turn the key on and measure resistance from yellow wire on passlock sensor side to bared section of low ref. Get a resistor that matches that value and install it from the bared section on the low ref circuit to the bcm side of the signal circuit. Passlock is now bypassed. If its not a perfect match for the value you can do a 30 minute relearn without any scan tools.
Turn ON the ignition, with the engine OFF.
 2. Attempt to start the engine, then release the key to ON, vehicle will not start.
 3. Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF.
 4. Turn OFF the ignition, and wait 5 seconds.
 5. 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.
Important: The vehicle learns the Passlock? Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.

 6. Start the engine. The vehicle has now learned the Passlock? Sensor Data Code and/or password.
 7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles.
