Where is the theft deterrent module on my 2001 Cadillac deville


It is located in the steering column (the ignition key receiver is part of it). The obvious question is why you need to locate it - unfortunately, the theft deterrent system is dependent on a number of different modules and sensors, and just replacing or disconnecting it will probably disable your car without fixing whatever problem you are having. Back to a dealer ...

2001 saturn lost keys to it. Got it to crank cut right back off secrity lights on bought a brain box for it and got 2keys with it. Still want crank I need to know what to do t could the box be bad ..


No ,the box is probably not bad , but you need to have it programmed . The dealer is the only one that can do that ? The keys don't matter .
The passlock sensor mounted to the ignition switch assembly is located inside the upper right side of the steering column. The passlock sensor contains two hall effect sensors: a tamper hall effect sensor and a security hall effect sensor. The tamper hall effect sensor is mounted on top of the security hall effect sensor. Should someone attempt to defeat the system by use of magnetic experimentation, the tamper hall effect sensor will activate first.
The passlock system is a vehicle theft deterrent system which deters drive-away vehicle theft by disabling engine operation if the ignition lock cylinder is not rotated with the proper mechanically cut key.
The passlock system is made up of an ignition switch assembly, passlock sensor, body control module (BCM), instrument panel cluster (IPC), and a powertrain control module (PCM).
The ignition switch contains a magnet mounted on the lock cylinder and a passlock sensor assembly which consists of security hall effect sensor, tamper hall effect sensor, and output resistors. A drill proof metal shield is also staked over the sensor housing.
The passlock sensor mounted to the ignition switch assembly is located inside the upper right side of the steering column. The passlock sensor contains two hall effect sensors: a tamper hall effect sensor and a security hall effect sensor. The tamper hall effect sensor is mounted on top of the security hall effect sensor. Should someone attempt to defeat the system by use of magnetic experimentation, the tamper hall effect sensor will activate first.
The BCM has the passlock controller integrated into it which controls the majority of the security systems logic. The BCM reads the data from the passlock sensor continuously. If the data is correct and has been received by the BCM within a specified time, the BCM will send a coded password to the PCM. The PCM will then allow the fuel injectors to operate.
The coded password for the security system is sent from the body control module to the PCM via the class 2 data link. If the password is correct and received within the specified time, the PCM will allow the fuel injectors to operate.
Sorry but you can't just replace parts , you need to know how the system works . You need to take this to a ASE certified repair facility that knows how it works .

Where is the anti-theft located on a1996 nissan pathfinder


No one should discuss anti theft systems on an open forum. If you are not a thief Take proof of ownership and an identity document to your Nissan dealer and deal to the problem there.

2001 mustang 3.8 no spark. an no power to crank sensor, is there a fuse for the crank sersor?


No there is not a fuse to the crank sensor, and if you were checking for voltage at the crank sensor ,you should see more than 1 volt but less than two volts at the crank sensor positive circuit which is the Dark blue wire, the crank sensor is a hall effect type sensor which generates its own voltage, It would be very helpful to know how this no start problem came about ! was any work recently been perform on your car ? it is also possible that you have a theft type problem with your car, which if for any reason your car"s theft system thinks its possibly being stolen, (example does not like the key or the electronic chip in the key is defective) may put it into to a theft lock down, ford uses different methods to keep the car from been stolen,some are disable the starter (example no crank) another is to disable to fuel pump circuit, or disable the spark,the easiest way to make sure this is not whats the problem, is to monitor your theft light, (located either in the gauge cluster or on top of the dash,) you have a red light or a red key that flashes or possible or just says theft, if the system is working correct when you first turn the key to the run position the light ,key or the theft light will flash three times and then go out and say out if it continues to flash you have a theft problem.there are many other possible reasons why you could have no spark such as broken wires ,wires rubbed bare and grounding out to engine ect, I could help you further but would need more information to help you further ,hopefully this will get you headed in the right direction

I need to know which fuse is connected to the security alarm


the security system is not directly fused, so there is no fuse to remove, also removing power to the system in any way will result in a no start condition.

It is probably not the anti theft system if it cranks over fast then slow it is your timing chain. If you want to try resetting the anti theft system disconnect the battery cables for 24 hours and reconnect them.
