Where is the alarm controll box on the 03 malibu


Alarm box ? You mean anti-theft system ?
The Passlock?"¢ System is provided in order to prevent vehicle theft if the ignition lock cylinder is forced to rotate or the ignition switch is operated while separated from the ignition lock cylinder case. If starting is attempted without authorization from the Passlock?"¢ System, the powertrain control module (PCM) will disable engine starting. Start disable may be in the form of fuel disable or starter disable, depending on engine application.
The components of the Passlock?"¢ System are as follows:
?€¢
The ignition lock cylinder and key


?€¢
The ignition lock cylinder case, including the Passlock?"¢ sensor


?€¢
The ignition switch


?€¢
The body control module (BCM)


?€¢
The security indicator on the instrument cluster


?€¢
The powertrain control module (PCM)


Body Control Module (BCM)
The body control module (BCM) contains the logic of the Theft Deterrent System. The BCM provides the battery positive voltage to operate the Pass lock" sensor. The BCM also measures the voltage of the security sensor signal circuit. The voltage measured will indicate whether the Pass lock sensor has been activated and whether the resistance value from the sensor is a valid value or the tamper value. If voltage measured is in the valid range, the BCM compares this voltage, voltage code, to a previously learned voltage code. If the voltage codes match, the BCM sends a class 2 message containing a password to the powertrain control module (PCM). If the voltage codes do not match, or the voltage is in the tamper range, or there is a circuit fault, the BCM will not send the correct password to the PCM, and the vehicle will not start.
there is nothing you can do , if your vehicle won't start you need to take it to the dealer or a ASE certified repair shop. Messing with the anti-theft system may render your vehicle useless .

What tools are needed to replace BCM?


Important: Perform new BCM setup when you replace Body Control Module (BCM). Refer to Body Control Module (BCM) Programming/RPO Configuration .
Disconnect the battery ground (negative) cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
Remove the left instrument panel insulator. Refer to Instrument Panel Insulator Replacement in Instrument Panel, Gauges and Console.
Disconnect the BCM electrical connectors.
Push the BCM up and move the bottom of the BCM away from and out of the mounting bracket slot in order to remove the BCM.
During Body Control Module (BCM) related service, the procedures below are designated to set-up the BCM correctly. Before you start, read these procedures carefully and completely.

Setup New Body Control Module (BCM)
Tools Required
Scan Tool (Tech 2) GM factory scan tool !
Important:
• Read this procedure carefully and completely.
• The BCM will not function properly if the Setup New BCM procedure is not performed.
• Perform the Theft Deterrent Re-learn procedure after successfully finishing the Setup New BCM procedure. If the Theft Deterrent Re-learn procedure is not performed after a BCM replacement, the following conditions may occur:
- The vehicle will not be protected against theft by the PASSLOCK system.
- The engine will not crank nor start. Your best bet is to take your vehicle to a dealer or a ASE certified repair shop who has proper tools .

My car starts and then after a few seconds it turns off and the immobiliser light comes uo on the dashboard. Can you tell me what the problem is?


The anti-theft system doesn't recognize the security pass word an disables the fuel injectors most likely ! an it set's a DTC -diagnostic trouble code in what ever module controls the anti- theft system . BCM - body control module , Theft deterrent module etc...
The powertrain control module (PCM) contains the remainder of the logic of the Theft Deterrent System. If a class 2 message containing a valid password is received from the body control module (BCM), the PCM will continue to allow the fuel injectors to operate. The PCM will allow the fuel injectors to operate until it decides there is no valid password coming from the BCM. If the PCM does not receive a class 2 message, or receives a class 2 message with an incorrect password, the engine will crank and will not run or will start and stall immediately.

Where is the alarm located on an 2006equinox


What alarm ? Anti-theft ?
The theft deterrent system on this vehicle is comprised of 2 separate systems, the Vehicle Theft Deterrent (VTD) System and the Content Theft Deterrent (CTD) System. The VTD prevents drive away theft by preventing the vehicle from starting. The CTD is the vehicle alarm system which discourages unauthorized entry into the vehicle. These systems are described and diagnosed separately within this section.
SECURITY Indicator
The SECURITY indicator on the instrument panel cluster (IPC) is controlled by the body control module (BCM) through the security indicator control circuit.
?€¢
The Vehicle Theft Deterrent (VTD) System contained in the BCM commands the instrument cluster to control the SECURITY indicator only when the ignition switch is ON. The VTD System uses the telltale as a malfunction indicator.


?€¢
The Content Theft Deterrent (CTD) System also contained in the BCM commands the instrument cluster to control the indicator only when the ignition switch is OFF. The CTD System uses the SECURITY indicator to identify system status.


It's software , a program inside the BCM ! An you can't just replace the BCM , it needs programming ! The dealer is the place to have that done ,most of the time ! If there is a SECRUITY light lit on the dash ,there is a DTC - diagnostic trouble code stored in the BCM , this code will point the service technician in the diagnostic path !
