I need to know where exactly is the fuse that controls the security system in a hhr chevy 2006 is located in the panel. I do not have a owners manual.


Security system ? your vehicle has two ! Content theft and anti-theft that prevents drive away theft ! Is the Security Indicator lit on the instrument cluster ? If the light is on it's not a fuse issue . You need to take or have towed to dealer . Nothing your going to be able to do .
The security indicator on the instrument cluster is controlled by both the VTD System and the CTD System. The security indicator is controlled by the body control module (BCM) via a discrete output.

What is the security code?


Your SECURITY light lit on the instrument cluster ? or you disconnected the battery an now the radio is locked ?
The theft deterrent system on this vehicle is comprised of the vehicle theft deterrent (VTD) system. VTD prevents drive away theft by preventing the vehicle from starting.
SECURITY Indicator The SECURITY indicator on the instrument cluster is controlled by the VTD system. The SECURITY indicator is located inside the instrument cluster. The SECURITY indicator is controlled by the body control module through the class 2 data line. The 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 indicator as a malfunction indicator.
Theft Deterrent
The "Theftlock" theft deterrent system is a feature on all base and uplevel radios. There is no need to program a security code into the radio as in past model years. The theft deterrent system now utilizes class 2 serial data to determine if the radio is in the appropriate vehicle. Each time the radio receives the "run" power mode message, it compares the VIN information it has stored to the VIN information received from a module on the class 2 serial data circuit responsible for transmitting that information. If a mis-match occurs, the radio display will indicate to the user the radio is locked. Once this takes place, a DTC will set, the radio will not respond to any button presses and become inoperative. The two scenarios able to cause this condition are:
?€¢
A radio is installed from another vehicle.


?€¢
A module which communicates on the class 2 serial data circuit which supplies VIN information to the radio is replaced and not properly setup with the correct VIN information for that vehicle.

The only way to unlock the radio is by using a scan tool. Always refer to the table in this section to diagnose the "Theftlock" DTC for further information.
So what problem are you having ?

I change the under the dash wiring harness on a 98 Chevrolet Sierra 4 by 4 it will start then immediately dies


GMC Sierra or Chevy silverado ? Do you have a SECURITY light lit ?
The SECURITY indicator is on the instrument cluster. If the SECURITY indicator flashes or if the SECURITY indicator lights continuously during the vehicle operation, refer to Diagnostic System Check - Theft Deterrent . If there is a problem the vehicle will start an run for just a second or two . It disables the fuel injectors .

Whr is my fuel pump reset button on my 2003 grand am? Its security lock, it wont get any fuel. It cranks but wont start. Not getting any fuel. First time ever happening


There is no reset button.
The problem could be the anti-theft system which would knock out the injectors and spark to the plugs.
If the security light is staying on, the problem could be the chip in the key.

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 !

If the security indicator is on while you are cranking it it is not recognizing the key it may have a bad key or a problem with the immobilizer control you would have to take to the dealer and try to reprogram keys

Sign of car with key warning light on dash


Here is a fix >

Security and Immobilizer System Indicator Symbols Symbols & Tell-tales
engine_immobilizer.gifsecurity_indicator_symbol.gifThese are Security and/or Immobilizer System Indicator symbols used by manufacturers. One of these symbols lights momentarily to indicate that the ignition switch is locked and will need the proper transponder-equipped key to re-start. The vehicle is immobilized otherwise. Green symbols will flash when the vehicle is immobilized.
lock.gifIf the symbol is visible when the vehicle is on, it indicates a malfunction in the security system. If the engine does not start with the correct key, and the security indicator remains on, the system may have a malfunction. You will need to contact your dealer in either case.
Keep the Symbol meanings with you!
