Hi Hwiracing,
Check the power feeds to the managements system sounds as though you've lost one power feed to the computer. In the event of that failing check the connections to the transponder. It sounds as though the injectors circuit are not opening and that could be the transponder could be the problem. Just an after thought, as it's a diesel, have you removed all the air from the fuel system?

The vehicle theft deterrent (VTD) system functions are provided by the theft deterrent control module. The VTD system prevents vehicle operation if a valid (learned) transponder PASS-Key?®III (PK3) ignition key is not used to start the vehicle. The theft deterrent control module has an exciter that is part of the theft deterrent control module as an assembly. The PK3 key has a transponder embedded in the plastic head of the key. The exciter is an antenna which is made up of wire coils which surround the ignition lock cylinder. The PCM enables the engines starter and fuel delivery system when it receives a valid (learned) password from the theft deterrent control module via the class 2 serial data circuit. The components of the VTD system are as follows:

One is under the hood in the engine compartment an Rear Fuse Block
Left rear of the passenger compartment, under the rear seat ! There are a couple of fuse's , but they power up the ignition an the PCM ,so you can't pull those ! Beside that if the PCM does not get a fuel enable signal from the anti-theft module the vehicle won't start . You can't just disable thing's on this vehicle ! If you have security light on steady or flashing you need to take it to someone who has a diagnostic scan tool that can check DTC'S - diagnostic trouble codes ! A code reader can not access these type codes !
Vehicle Theft Deterrent (VTD)Circuit Description
(VTD) Theft Deterrent System Components
Ignition Key (Transponder) The ignition key for the (VTD) theft deterrent system is a typical ignition key with a transponder pellet located in the plastic end of the key. The ignition key transponder value is used to determine if a valid ignition key is being used to start the vehicle, there are approximately three trillion different transponder values available. This vehicle has two types of ignition keys.
?€¢
Master key (black plastic end) which can start the vehicle and lock/unlock all door locks, all storage compartments and the rear compartment lid lock.


?€¢
Valet key (gray plastic end) which can start the vehicle and unlock/lock all doors, but can not unlock/lock the storage compartments, or rear compartment lid lock.

Important: The transponder values are not readable and can not be serviced separately.
Theft Deterrent Module The theft deterrent module contains the software for controlling the VTD System. The theft deterrent module uses the following inputs and outputs to control the VTD system.
Inputs ?€¢
Battery voltage from the underhood fuse block PCM/BATT fuse, circuit 240 (ORN).


?€¢
Ignition start voltage from the ignition switch, circuit 1390 (WHT).


?€¢
Ground, circuit 450 (BLK).
Outputs Password exchange with the PCM (fuel enable), class 2 message circuit 1807 (PPL).
Powertrain Control Module (PCM) The PCM verifies that the passwords received from the theft deterrent module via the class 2 serial data line are valid. If a password is invalid the PCM disables the fuel delivery system. If the password is valid the PCM enables the fuel delivery system.
Starter Relay The starter relay is controlled by the PCM module via class 2 serial data (CKT 1807 PPL). If the theft deterrent module measures the correct transponder value, the PCM module switches the starter enable control (CKT 447 YEL) to ground. The relay is energized if the ignition switch is in the START position and the gear selector is in the PARK or NEUTRAL positions.

How toprogramm car key toyota matrix


  • 1 First you will need to purchase a blank Toyota transponder key. You can do this from the dealership, a locksmith, or an online source such as eBay. Once you have the key, take the blank key and the master key to a locksmith that he or she can duplicate the key. This will be much cheaper than the dealership.
  • 2 Now that you have the newly cut key and the master key, you can program the Toyota transponder key. Sit in the driver's side of the Toyota vehicle. Press and release the brake and gas pedal simultaneously.
  • 3 Insert the master transponder key. Do not turn it. Push and release the gas pedal 5 times within at least 15 seconds of inserting the master key.
  • 4 Press and release the brake pedal 6 times within 20 seconds of completing step 3, then remove the master transponder key.
  • 5 Insert the newly cut transponder key into the ignition, but do not turn. Press the gas pedal once.
  • 6 Wait up to 2 minutes or whenever the security light on the dashboard turns off. Once the light goes off, remove the new transponder key and press the brake pedal once. The new transponder key should now be programmed. Test the key by attempting to start the engine. If the engine does not start, repeat the steps above.

    2006 Cobalt ss will not start


    The key is chiped , does it have a padlock an car symbol light on the instrument cluster when you turn the key on ? Do the headlamps work ? shine bright ? Do you have a volt meter ? Check battery voltage . Go to http://www.bbbind.com/free_tsb.html free wiring diagrams . Enter vehicle info. year , make , model an engine size . Under system click on electrical distribution , under subsystem click on power distribution . Check power at the crank relay , plus you need to know what happens when you turn that key to start . Computers involved .Do you know about relays ?

    Moving the ignition switch to the START position signals the body control module (BCM) through discrete inputs from the ignition transducer that engine crank has been requested. The BCM verifies that theft is not active and sends a serial data message to the engine control module (ECM)/powertrain control module (PCM) requesting engine start. The ECM/PCM receives a 12-volt signal from the park/neutral position (PNP) switch or clutch pedal start switch notifying that it is safe to start the engine. There is a splice on this circuit in the fuse block-underhood that supplies power for the starter relay coil. The starter relay coil control circuit is then grounded by the ECM/PCM closing the switch in the starter relay suppling 12 volts to the S-trminal of the starter. Ground is supplied through the engine block.
    A scan tool of professional type would be a good tool to have to diagnose this .

    The vehicle theft deterrent (VTD) system functions are provided by the theft deterrent module (TDM). When an ignition key is inserted into the ignition lock cylinder and the ignition is switched ON, the transponder embedded in the head of the key is energized by the exciter coils surrounding the ignition lock cylinder. The energized transponder transmits a signal that contains its unique value, which is received by the TDM. The TDM then compares this value to a value stored in memory. This is the learned key code. If the value is correct, the TDM sends a random generated number to the transponder. This is called a challenge. Both the transponder and the TDM module perform a calculation on the challenge. If the calculations match, the TDM sends the start enable message via the serial data circuit to the engine control module (ECM). If either the transponders unique value or the calculation to the challenge is incorrect, the TDM will send the start disable message to the ECM via the serial data circuit. The components of the VTD system are as follows:
    • TDM
    • ECM
    • Ignition key (Transponder)
    • Ignition lock cylinder
    • Security indicator

    Is the light on . when trying to start the vehicle ?

    Vw beetle does not start. seems like its some kind of anti theft protection. the car/key icon lights up, it turns over for a second , then off. this is the first time this has happened, but we bought it...


    First of all you need to programm all ignition keys using suitable diagnostic equipment (VAS, VAG-Com) connected to the data link connector of the car.

    You have an electronic immobilizer key recognition problem. Now your key chip is not recognized by the transponder antenna fitted on the ignition switch barrel.

  • Everytime when you had a new key you must programm all available ignition car keys before trying to start the engine with this new key !!!

    This warning lamp indicates that the engine is locked by the immobilizer system, and the engine start sequence must be repeat again.

    From year 1995 in Audi-VW (VAG) cars is used engine immobilizer. The VAG group immobilizer system consists of an immobilizer ECU which controls the recognition of keys and the Engine Management ECU system. Immobilizer is activated when the ignition key is removed and, together with the engine control unit, largely prevents unauthorized starting of the engine. The system uses a transmitter and receiver unit in the ignition key (transponder). Whenever an attempt is made to start the engine, it transmits a new code to the car's electronics. The immobilizing is only cancelled and car motor electronic receives permission to start engine if the key sends a right authorization code.

    Engine turns over, stalls out and alarm goes off


    These vehicles use Fords Securilock transponder system to prevent vehicle theft. Basically, there is a little radio chip in the key that transmits a code to the computer when you start the car. If this code doesn't match the computer, the computer disables fuel and spark so the engine won't run. If you have a spare key, try that to see if it works. If it doesn't work, then the Securilock system needs service. Unfortunately only the dealer can service this system because it is integrated into the vehicle computer.

    If your spare key works, then the key you tried to use has a damaged transponder and the key needs to be replaced. If you don't have a spare key, contact a locksmith and have them make you a new key. I have to warn you, transponder keys are not cheap. They can cost easily $75 and some even go for $150. But, that is probably cheaper then having Ford make one and even if the spare doesn't work, when you get the system fixed by the dealer they can program your spare key as well so you don't waste the money on the key.

    Does the security light flash or come on steady ? Have a lot of thing's on your key ring ? Other key's with transponder inside , Do you know what a transponder is ?

    The Ignition Key (Transponder)
    The ignition key for PASS-Key® III equipped vehicles is a typical ignition key using a transponder pellet located in the end of the key. The ignition key transponder value is used in order to determine if a valid ignition key is being used in order to start the vehicle. When the ignition key is inserted into the ignition cylinder and the PASS-Key® III module detects the ignition voltage (the ignition switch is in RUN or START) the module measures the transponder pellet value. The PASS-Key® III module validates this value and performs the following functions:
    • If the ignition key transponder value is valid, the PASS-Key® III module performs the following (system enable) functions:
    - The PASS-Key® III module sends a pulse width modulated signal to the PCM to request fuel enable.
    - The PCM enables the fuel system.
    - This function enables the engine to start.
    • If the ignition key transponder value is invalid, the PASS-Key® performs the following (system disable) functions:
    - The PASS-Key® III module does not send the fuel request signal to the PCM.
    - The PCM does not enable the fuel system.
    - This function does not enable the engine to start and run. The engine may start and then stall due to residual fuel in the fuel system.
    The PASS-Key® III module can identify up to 10 valid key codes to operate the vehicle.

    Having excess thing's on you ring , including other PASS-Key® III keys , can confuse the computers .
