Antitheft or Security system failure is a common problem on GM vehicles. Every time you put your key in the ignition, the vehicle's security system reads the signal from your key to make sure it is OK to run. When it recieves the "correct key" signal, the security system allows the starter to turn over, and/or the fuel injectors to function and your car works like it normally does every day. If you were to use a different key, or try to hotwire it, the system would shut down these parts of your car, thus making the vehicle completely immobile. This is GM's way of preventing vehicle theft. The problem is that the system is known to fail quite commonly. It has been failing consistantly for around 30 years. When it fails, two things can happen. First, you turn the key and nothing happens at all. Lights work, radio works, windows work... just not the starter that you need to start the vehicle. This is a "starter immobilizor". Second, you turn the key and the vehicles starts just fine, but then stalls in 2-5 seconds. This is a "fuel immobilizor". It literally cuts off the fuel injectors and stalls the vehicle to immobilize it. These are normally, but not always followed by a light on the dash that says SECURITY or ANTITHEFT. These lights are to inform you of the system's failure to collect the information it needs from your key to the computer. If your security/antitheft light is on, odds are you will be stranded soon, if not already. Remember that the security system controls the security light. If the system is failing, the light may never warn you of the failure. There is a lot of info on this site that you can read up on. http://vatspasslockpasskeysecurityhelp.yolasite.com/

Where is the BCM located in 2004 Oldsmobile silhouette?


BCM Identification
This vehicle is equipped with 1 of 3 types of BCMs. The BCM type installed on this vehicle is based on the vehicle equipment, point of sale, and option content.
Refer to On-Board Diagnostic Features for more information on how to identify the BCM type installed by using the on-board diagnostic feature. The following identifies the functions and basic option content of all 3 BCM types:
BCM Type 2
BCM type 2 is the base BCM that provides all standard BCM functions. Refer to the BCM function table for type 2 BCM.
BCM Type 3
BCM type 3 provides all of the features of the BCM type 2 plus keyless entry. Vehicles with RPO AU0 are equipped with a BCM type 3.
BCM Type 4
BCM type 4 provides all of the features of the BCM type 2 and type 3 plus content theft deterrent. Vehicles with RPO AU0 and UA6 are equipped with a BCM type 4.

On-Board Diagnostic Features
This vehicle is equipped with an on-board diagnostic feature capable of performing the following functions:
• Feature Customizing
• Displaying DTC codes
• Clearing DTC codes
• Input/Output Diagnostics
Feature Customizing Mode
The feature customizing mode is used to configure the BCM to function in various applications. The BCM can be customized to change the following vehicle functions:
• Interior Lighting Features
• Door Lock System
• Keyless Entry System
• Content Theft Deterrent System
In order to enter the feature customizing mode perform the following steps:
Turn the ignition switch to the LOCK position.
Remove the BCM PRGRM fuse.
Turn the ignition switch to the ACC position.
When entering the feature customizing mode, the BCM first identifies what type of BCM is installed on the vehicle by flashing the fasten seat belts indicator and sounds the chime 2, 3 or 4 times depending on the type of BCM used on the vehicle. There are 3 different types of BCM that can be installed on the vehicle based on the vehicle option content that matches the BCM capabilities. Ensure that the BCM installed on the vehicle is compatible with all of the features on the vehicle. Refer to Body Control System Description and Operation for BCM identification.
For more information on features that can be customized, refer to Personalization Description and Operation in Personalization.

Complete the following steps in order to enter the diagnostics mode:
Turn the ignition switch to the LOCK position.
Remove the BCM PRGRM fuse.
Turn the ignition switch to the ACC position.
Quickly turn the ignition switch from the ACC position to the LOCK position then back to the ACC position within 1 second.
The BCM will enter the on-board diagnostic mode and flash the fasten seat belts indicator and sound the chime equal to the number of DTCs stored in the BCM memory. If no DTCs are stored, the BCM will not flash the fasten seat belts indicator or activate the chime.
The BCM flashes and sounds the first DTC with the lowest number, pauses, then continues with the next DTC until all of the DTCs are read. With a DTC 1, the BCM will only sound the chime once, and the fasten seat belts indicator may not flash. Once all of the DTCs are read, the BCM repeats this sequence 3 times.
Important: If the fasten seat belts indicator does not flash, and the chime does not sound, complete the following procedure in order to confirm that the BCM has entered the diagnostics mode:
Ensure that all of the vehicle doors are closed.
Open and close any vehicle door.
Fasten and release the driver seat belt.
The BCM sounds the chime when receiving an input signal such as Drivers door, Passengers door opening or turning on the courtesy lights when the BCM is in the diagnostics mode. Make sure these inputs are working correctly in order to prevent a false diagnoses.
If the BCM does not sound the chime upon opening a door or turning on the courtesy lights, repeat Step 1 of Entering the diagnostics mode. If the BCM does not enter the diagnostics mode, then refer to Cannot Enter BCM Diagnostics .
Clearing DTC Codes
After entering the diagnostics mode press and hold the Unlock switch for 4 seconds. The BCM will erase all history DTC codes. If a circuit is still shorted, the BCM will immediately store a history DTC code.
Input/Output Diagnostic Mode
After the BCM reads all of the DTCs in the memory, the BCM enters the Input/Output Diagnostic Mode.
The BCM flashes the fasten seat belts indicator and sounds the chime once when any of the following inputs are activated:

2004 Lincoln navigator interior lights don't come on when unlock. Sometimes auto headlights don't come on, seats don't move. Liftgate won't open until vehicle is started. Is this a relay or fuse?


. When you open the door or just unlock the door the lights don't come on ?
Vehicle Security Module The vehicle security module receives inputs from the following:
  • door ajar switches
  • keyless entry keypad
  • ignition switch
  • remote keyless entry transmitter
The vehicle security module uses these inputs to control an output signal to the instrument cluster which controls the battery saver relay and courtesy lamp output.
Interior Lighting Systems The instrument cluster grounds the battery saver relay and supplies the power for courtesy lamps when any door ajar switch is opened, or the interior lamp (headlamp) switch is closed. The instrument cluster then supplies voltage to the interior lamp circuit. Vehicle speed must be less than 24 kph (15 mph) for the instrument cluster module to keep courtesy lamps on. The interior lamps will remain illuminated for up to 25 seconds after all doors are closed unless the instrument cluster module receives an input from any of the following:
  • voltage from the ignition switch
  • a vehicle speed signal
  • input from the keyless entry keypad through the vehicle security module
  • input from the remote keyless entry transmitter lock or panic switch through the vehicle security module
Do you know what body control system DTC'S - diagnostic trouble codes are ?
Instrument Cluster Diagnostic Trouble Code Index DTC Description Source Action B1342 ECU is Defective Instrument Cluster REFER to Section 413-01 . B2499 Courtesy Lamp Output Failure Instrument Cluster Go To Pinpoint Test A . B1320 Driver Door Ajar Circuit Open Instrument Cluster Go To Pinpoint Test A . B1328 Passenger Door Ajar Circuit Open Instrument Cluster Go To Pinpoint Test A . - All Other DTCs Instrument Cluster REFER to Section 419-10 .
Principles of Operation
The autolamp system provides light-sensitive automatic on/off control of the headlamps and parking lamps controlled by the vehicle security module when the headlamp switch is in the autolamps position. When the ignition switch is turned to the RUN or START position with the autolamps feature already enabled and the ambient light level is dark, the vehicle security module will request the headlamps and parking lamps be turned on. When the autolamps are disabled, the vehicle security module will request the headlamps and parking lamps to be turned off, regardless of the ignition switch position. When the vehicle security module has turned on the exterior lamps and the ignition is turned to the OFF or ACCY position, the exterior lamps will remain on for an additional time specified by the customer or the headlamp switch is turned off.
When the autolamps have been enabled and the ignition switch is in the RUN/START position, the vehicle security module will request that the exterior lamps be turned on or off based on ambient light level. If the vehicle enters darkness for at least 15 seconds, the vehicle security module will request the exterior lamps on. If the vehicle enters light for at least 15 seconds, the vehicle security module will request the exterior lamps off. By delaying turning on and off the exterior lamps during short periods of darkness and light, the vehicle security module prevents the exterior lamps from flashing on and off.

  • The autolamps are inoperative - do not operate correctly
  • Circuitry.
  • Photocell.
  • Headlamp switch.
  • Vehicle security module.
  • Go To Pinpoint Test G .

Power Lock
The power lock/unlock feature requests all of the vehicle doors, including the liftgate, be locked or unlocked upon a customer request from any interior door lock switch in the vehicle. The power door locking system functions independently of ignition status or vehicle speed. When the vehicle security module receives an unlock/lock command from any door lock control switch, the vehicle security module will activate relays internal to the module to supply the correct power and grounds for the door lock actuators.
Your best bet , take it to a qualified repair shop .

Do you know anything about automotive electronic's ? Control modules ?
Vehicle Security Module
The vehicle security module receives inputs from the following:
  • Door ajar switches
  • Keyless entry keypad
  • Ignition switch
  • Remote keyless entry (RKE) transmitter
The vehicle security module uses these inputs to control an output signal to the instrument cluster which controls the battery saver relay and interior lamp relay. The battery saver relay and the interior lamp relay are internal to the instrument cluster, and are not replaceable. There could be a faulty switch input to the I/C - insturment cluster , causing the vehicle security module to activate the lock's an light's .
Interior Lighting Systems
The instrument cluster grounds the battery saver relay and interior lamp relay coils when any door ajar switch is opened, or the interior lamp (headlamp) switch is closed. The interior lamp relay then supplies voltage to the interior lamp circuit. Vehicle speed must be less than 24 km/h (15 mph) for the instrument cluster to ground the interior lamp relay. The interior lamps remain illuminated for up to 25 seconds after all doors are closed unless the instrument cluster receives an input from any of the following:
  • voltage from the ignition switch.
  • a vehicle speed signal.
  • input from the keyless entry keypad through the vehicle security module.
  • input from the RKE transmitter unlock or panic switch through
  • the vehicle security module.

DTC B2957 Security System Sensor Data Circuit Low
The Passlock System is provided in order to prevent vehicle theft if the ignition lock cylinder is forced to rotate. The Passlock controller reads the coded Passlock data signal. The data consists of a voltage generated by a voltage divider network created between the Passlock assembly and the Passlock controller. If the data is correct , indicating rotation of the lock cylinder with the proper mechanically cut key, then the Passlock controller sends a password to the powertrain controller via serial data to indicate that engine starting should be allowed. The Passlock controller also interfaces with the driver displays subsystem to indicate, via the security indicator, the Passlock subsystems status and acute subsystem failures.
Test Description
The numbers below refer to the step numbers on the diagnostic table.
This step tests for proper operation of the 5-volt reference circuit from the BCM.
This step checks for a voltage drop through the Passlock resistor located in the ignition switch. Voltage in this step will vary due to unique differences in each individual Passlock resistor.

I see a lot of the end result of people that have no clue how these systems work . When they can't fix it ( get the vehicle to start an run ) They bring them to the dealer. Then they want to complain how much it costs . If they would have brought it to us first ,wouldn't have been that way . Plus if the BCM is the trouble it needs to come to the dealer programming any way .

How do i reset the alarm on my 2003 Chevy Trailblazer...I can't stay my truck.


Hello Narisol,


Excerpt from the 2003 Owners Manual.


Passlock

Your vehicle is equipped with the Passlock theft-deterrent
system. Passlock is a passive theft-deterrent system.
Passlock enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used or the ignition lock cylinder
is tampered with, the fuel system is disabled and the vehicle
will not start. During normal operation, he SECURITY light
will turn off approximately five seconds after the key is turned to
RUN. If the engine stalls and the SECURITY light flashes,
wait about 10 minutes until the light stops flashing before trying
to restart the engine. Remember to release the key from START as
soon as the engine starts. If the engine does not start after
three tries, the vehicle needs service. If the engine is running and the
SECURITY light comes on, you will be able to restart the engine
if you turn the engine off. However, your Passlock system is not
working properly and must be serviced by your dealer. Your vehicle is not protected by Passlock at this time. You may also want to
check the fuse. See Fuses and Circuit Breakers on page 5-85.
See your dealer for service. In an emergency, call the M
Roadside Assistance Center. See Roadside Assistance Program on
page 7-5.


Excerpt from the 2003 Owners Manual.

Testing the Alarm The alarm can be tested by following these steps:
1.
From inside the vehicle, Iower the driver's window and open
the driver's door.
2.
Activate the system by locking the doors with the power door
lock switch while the door is open, or with the remote keyless entry transmitter.
3.
Get out of the vehicle, close the door and wait for the SECURITY light to go out.
4.
Then reach in through the window, unlock the door with the manual
door lock and open the door. This should set off the alarm. When
the alarm is set the power door unlock switch is not operational.
If the alarm does not sound when it should but the headlamps flash, check to see if the horn works. The horn fuse may be blown. To
replace the fuse, see Fuses and Circuit Breakers on page 5-85.
If the alarm does not sound or the headlamps do not flash, the
vehicle should be serviced by your dealer.

Why does security ligh flash while driving


The security icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

1999 oldsmobile cutlass computer will not communicate with car


When the motor was replaced , was the original PCM changed as well ? Did you have the anti-theft system programmed . Theft - system light on -DTC'S - diagnostic trouble codes are stored . Need a factory or professional scan tool read these codes . The other computers on the vehicle will communicate . BCM
Important: Due to component variability, the vehicle theft deterrent (VTD) system must have the learn procedure performed regardless, if the vehicle starts on the first ignition cycle after a VTD repair.
All codes in the theft deterrent module must be cleared for a relearn.
The vehicle theft deterrent system is designed in order to prevent vehicle theft by disabling the fuel injectors unless the lock cylinder is correctly engaged by a mechanical key. The theft deterrent system uses the following 4 components for theft prevention:
• The lock cylinder
• The ignition switch
• The body control module (BCM)
• The powertrain control module (PCM)
When starting the engine, the PCM searches for a password from the BCM through the Class 2 serial data circuit. If the password is not recognized or not present, the PCM will disable the engine. Two modes of tamper detection are provided:
• No password received
The engine will start and stall quickly. SECURITY telltale will flash on the instrument panel cluster (IPC) and then stay ON steady.
• Incorrect or disable password received (More than 3 invalid passwords are received)
The engine is disabled for at least 10 minutes and the SECURITY telltale will illuminate solid on the IPC during the 10 minutes.
After the vehicle has passed theft detection, the PCM will continue normal operation.
