First of all make sure all your battery connections are Clean and Tight. If they are and all your dash lights come on and its not starting But its cranking over Your anti theft alarm may have gotten activated. You may have to leave your Key in the On position for 20 minutes to reset the alarm. Not cranking just in the on position, Now if its not Cranking and your hearing a clicking sound it may be your starter. I have sometimes tapped on the stater with a deadblow hammer and had someone crank it over Making sure your in park foot on brake and being EXTREMLY Carefull that you are not going to run someone over. If that don't get you going Get back to me we can do some more trouble shooting. Get that thing going for you. Thanks, Bear001

Need to know where the tdm is on a 1997 Cadillac deville can't get security system to shut off should I replace ecm ? Please help


It's hard to get the SECURITY light to go off when you don't know how it works ! Replacing the PCM could cause you more problems too . If a replacement PCM is being installed it must be programmed (flashed) using the latest Techline programming procedures.
Having the vehicle check for DTC ' S - diagnostic trouble codes would be the first step.

DTC P1630 Theft Deterrent Learn Mode Active
DTC P1631 Theft Deterrent Start Enable Signal Not Correct
DTC P1632 Theft Deterrent Fuel Disable Signal Received

This anti-theft system does not use a TDM - theft deterrent module . The instrument cluster is the controlling module . Look at a wiring diagram here
http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model engine . Then under systems click on body & accessories , then in subsystem click on security / anti-theft . Click the search button , then on the blue link .You mite be able to do a by-pass if the contacts inside the key lock cylinder is the problem . You can check it with ohm meter . The key has a resistor pellet on the side , you can check the value with ohm meter , find the two wires under the dash at the steering column . Two white wires inside a yellow or orange sheathing . There are videos on youtube !

97 cutless supreme it will start and only run about 10 seconds then die


Does it have anti-theft system ?
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) Do you have a SECURITY light lit on the dash ?

Why can't i get my car to go in gear?


Parking on an incline you "must" use the parking brake. You have damaged the "TBLS" Tranny Brake Lock Switch. Try turning your ignition to just before the "on" position and shifting into Neutral. Then start the car while in neutral and then shift to drive or reverse. Then drive it to a Chevy dealer for repair. This is a major repair requiring special tools.

I replaced the battery in a 06 impala ls but now it says service theft deterrent system how do i clear that message


Check your owners manual for a way to turn the anti theft sytem off. I have a car that when i take the terminals off or the battery dies, the theft system is active and the parking lights flash. There might be a small button somewhere under the dash you must hold for a certain amount of time and then turn the key. If you have your owners manual, it'll be in there.

I just installed an after market stereo in my impala.Now the starter doesn't engage. Is their a wire on the wire harness that affects this?


In the wiring diagrams there is a COMPUTER DATA LINES SYSTEM wire. From what I have read the radio won't cause the car not to start. Did you make sure you didn't drain the battery? Is the Theft Deterrent light on? If it is you're going to need a scanner to get the codes. This is what the Theft Deterrent system does with the radio.


I think if the Theft Deterrent light is on you will have to start there if not just diag a no crank condition.

My dad owns a 2003 CTS. While driving the car he gets the displayed message "starting disabled remove key" and the car shuts off. He puts the car in NEUTRAL and WITHOUT removing the key, starts the car...


STARTING DISABLED REMOVE KEY
Refer to Theft Systems Description and Operation in Theft Deterrent

STARTING DISABLED REMOVE KEY
The radio illuminates the STARTING DISABLED REMOVE KEY message when the VTD system has disabled the starting system. The radio receives a message from the theft deterrent control module via the serial data circuit requesting illumination.

Your best bet ,take it to Cadillac dealer and have it checked . Could have DTC'S - diagnostic trouble codes
DTC B1015
DTC B1016
DTC B3031
DTC B3055
DTC B3060
DTC B3090
DTC B3935
DTC B3976
DTC P1629
DTC P1630
DTC P1631

The theft deterrent module or the insturment cluster or the ECM is not seeing correct info.
The vehicle theft deterrent (VTD) system functions are provided by the theft deterrent control module. 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 theft deterrent control module. The theft deterrent control module then compares this value to a value stored in memory, learned key code. If the value is correct the theft deterrent control module sends a random generated number to the transponder, this is called a challenge. Both the transponder and the theft deterrent control module perform a calculation on the challenge, if the calculations match the theft deterrent control module sends the fuel continue password 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 theft deterrent control module will send the fuel disable password to the ECM via the serial data circuit. The components of the VTD system are as follows:
• Theft deterrent control module
• Engine control module (ECM)
• Ignition key (Transponder)
• Ignition lock cylinder
• Security indicator
