In most cases the theft deterrent system in your 2007 Chevrolet Impala will reset itself in 10 minutes. You can also remove the fuse for 10 seconds and replace it to reset the system.

DTC P1631 Theft Deterrent Fuel Enable Signal Not Correct

The powertrain control module (PCM) controls the fuel injector operation and the starter operation based on a vehicle theft deterrent (VTD) password from the vehicle body control module (BCM). When the ignition is first turned ON, the BCM sends a programmed theft deterrent password to the PCM. The PCM acknowledges the password and responds to the BCM that normal fuel injector and starter operation will continue. If the PCM detects an incorrect password, a theft deterrent system failure, or an attempted vehicle theft, DTC 1631 will set. The engine will not start or crank as long as the condition is present.

Diagnostic Aids
DTC P1631 indicates that the vehicle theft deterrent password that the PCM has learned does not agree with the password received from the VTD system. This condition can occur if the BCM has been replaced and the PCM Password Learn function has not been enabled. If the BCM has been replaced, the password must be relearned.

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

nope theft security system is part of the bcm and pcm,no way to bypass,it will disable car so you cant crank it.

it resets the anti theft system, so vehicle will start. all gm vehicles from 97-2005, contain a anti theft system called a passlock system. go to tubesound.com to disable passlock for good. (just type in your problem when page comes up).

GM Yuck! I'm surprised you haven't had a bad anti-theft system yet!

No heat is due to a bad heater core. Or the flap that directs the air inside the venting gets stuck in one position and you have to tear apart the whole dang thing to get to it.

Hi, There are two types of fuse boxes on the Chevy 2000-2005.

An internal one and an exterior one. If you go to the relevant web site, you can watch a tutorial.

I hope this helps.
