Skip to content. Quick links. Logout Register. After some testing, i have managed to figure out where and how to "disable" the immobilizer code check in the T7 binary, bellow is a small writeup of how. What does this do? This "Hack" will remove the immobilizer code check completly from the binary.
However, the twice functionallity will still be intact so you still have to have the appropriate key to start the car, therefor this should NOT affect the cars "security features". You can after theese changes, upload a bin with either your correct immobilizer code or a bin with a faulty immobilizer code and it will still start and should not give any errors what so ever.
How is this tested? This was tested and confirmed firstly in his car, after that i asked Aeroride to do the same in his with twice and everything - Both tests where a success! Saab Ng Vector 2. Saab Aero, Power Commuter Saab 2. I didn't post it because of the other thread about using open bins to run without immo on T7. I can't even remember what i did, it's so long ago. I'll PM you the file Manick. I know some people but line of zeros in their binaries because they dont want other people knowing their immo.

Placebo answered 7 years ago. Is this true? It has to actually be reset? I've recently run into the same issue, except I had my BatteryPlus solder my batteries on my alarm earlier this summer, and it wasn't until just recently Beg of Dec that the SID warning started, and even an occasional 5 second warning. Car alarm goes off randomly. Cannot lock the car with the fob, the alarm goes off, cannot lock the car with the key, nor simply with the lock on the door.
The alarm goe I was driving yesterday on highway ND towards end of 90 mile trip, car was making a high pitched whistle noise which got louder upon acceleration. Car sat for 4 hours. On my return trip noise wo The thing lights up lilke a christmas tree and the speedo's totally dead, stuck at zero.

However, if you don't want to take the time to lock your Saab every time you exit the vehicle, you'll find it easier to disable the alarm entirely. Place the key in the ignition and start the vehicle.
Like other vehicles, the Saab has an alarm box under the driver-side dash board. Press and hold in the override button until the alarm chirps one time. Lift and secure the hood of the vehicle so it doesn't fall on you, then look for the fuse box.
On Saab vehicles, the fuse box sits to the right of the engine, next to the firewall. Locate the correct fuse. Most fuse boxes have the fuses labeled clearly.
If the fuses aren't labeled, look at the diagram on the back of the fuse box cover to determine which fuse connects to the alarm.Find duplicate elements in array in c
Pull the fuse. Use a fuse puller tool to remove the fuse from the fuse box carefully. Put the cover back on the fuse box, and close the hood of the car.

Alarm wiring maps aren't public knowledge to keep them out of the hands of car thieves. Warning In some Saab vehicles, the fuse that controls the alarm also controls the air conditioner. If your air conditioner isn't functioning properly, replace the fuse and take the vehicle to a Saab dealership to have the alarm disabled via the wiring.

Unfortunately I had to open the door using the key which set off the alarm.
To disable the horn from going off with the door open, you will need to remove fuse The fuse panel is on the left hand side of the dashboard, it cannot be accessed when the door is closed. I hope it helps, feedback is always welcomed and if you have questions or need help feel free to comment and I will respond as soon as possible. Thank you! Step 1. Remove the plastic door sill from the drivers side.
Use a screw driver or trim removal tool and carefully pry under the door sill, start at one corner and work your way across. Step 2. Once the driver side door sill is removed, you will have to remove the 4 torx bolts T40 holding in the seat. There are 4 bolts, one in each corner around the seat. The images below show the location of each bolt starting with the top left corner of the seat as if you were sitting in it, then the top right corner, then the bottom left corner and finally the bottom right corner.
Step 3: Pull up on the carpet from where the carpet met the drivers side door sill. You should see the alarm immobilizer unit. It might be plastic or metal depending on the year. There are 2 nuts 10mmone on each side that need to be removed and the electrical connector disconnected before the unit can be removed.
Installation is the reverse of removal. Thank you and if you have questions feel free to comment. You are commenting using your WordPress.SAAB 93 NO CRANK, NO START, NO COMM & KEY STUCK

The key is read by the computer and if it matches, it will enable all systems to start the car. If the key does not match, the car will only crank but not start. While taking the car to a dealership or locksmith is an option, it could get expensive because you are at their mercy.

When you insert the key, a coil near the ignition ring picks up the RFID signal from your key and sends it to an amplifier. The amplifier then decrypts it and sends it to the ECU. If the key code matches the stored values, the engine will start. However its location under the dash means you will have to remove the entire dash pad. The procedure for reprogramming is similar, however you will have to short two wires on the OBDII port to perform a hand-shaking procedure between the ECUs to program new keys.
This is where you need to get a programmer to connect the chip to your PC. You can either buy a USB programmer from eBay or make your own to communicate to the serial port.
The components required are fairly basic, three 4.
If you do have problems reading and writing from the chip, you have to short the crystal on the board. PonyProg, a free serial device programmer was the software used to read information from the serial port and "dump" the EEPROM's contents. First go to setup under options. The content should appear as an array of HEX characters. Each key has a unique 8 digit HEX code.
There are also bits to indicate key count, enable programming mode and valet lockout. After a lot of experimentation, it was observed that there are three distinct keys. Each key is an 8 digit HEX value, repeated three times.School library ideas displays
It is split across two groups of four, but there is symmetry in their positioning within the dump. This must be zeroed as well. When reconnected to the car, the ECU will be in auto-programming mode and will accept new keys as per the procedure below:.We are a team of ASE certified mechanics that have created this guide for you to help save you money and get you back on the road.

Most cars today have a security system built into the electrical system BCM - Body control module to deter from theft. The problem is it can sometimes stop the person that owns the car from starting the engine as well.
These anti-theft systems can sometimes get the operational sequence out of sync which makes the system think the car is getting stolen epically after a repair job. This can sometimes happen when there is no one in the car but the window is rolled down while the car is locked. Someone will reach their hand inside and unlock any of the doors. Another common way for the system becoming triggered is to simply disconnect the battery to install a new unit or if the battery is allowed to go dead and then jump started.
These can sometimes cause an electrical surge triggering the immobilizer system. Car alarms are designed to prevent burglary of the car and warn the owner if a theft attempt is being made. Usually a car alarm will output a high pitched sound when the system is triggered by vibration, closed or opened trigger switches or sensing of small and fast changes in battery voltage. Car alarms can also monitor sensors like infrared, microwave, ultrasound or tilting of the vehicle in the case of unauthorized towing.
Some cars have alarm systems which send out SOS signals to a cell phone number in case of breakdown or theft. Alarm systems are also incorporated within a navigation system to increase the security of the car. The navigation system will send out a ping signal so the car can be received. The security system can also be used to locate the car in large parking lots by using the conformation chirp on the remote fob. Sometimes a car alarm can give out a false alarm when it feels vibrations of thunder or a passing truck.
Sensors need to be adjusted properly otherwise it can trigger the device even when a person accidentally touches the automobile as well. For people who want added security for their cars can have a police tracking system installed with the help of services like On Star.
These systems come with an additional cost which is to be paid on a regular basis. Security systems utilize a remote controller key fob so a user can disable the alarm from a distance. The remote control feature is very convenient if the system is triggered by a false alarm. A key fob can integrate a variety of functions such as a LCD screen option which can project the image of a part of a vehicle that is under threat by a thief is one example.
A simple response to this question is in most cases no. Security systems are designed throughout the main PCM and BCM which control a major part of the vehicle's operating system.Original Poster. Search My Stuff What's New 3 12 24 Bypassing The Immobiliser Ignition Only. Prev of 4 2 3 4 Next. Chimpafrolic Original Poster 9, posts months. First off before I start the answer should be sent to me by PM for obvious reasons.
For the last six months I have been suffering from an intermittent starter fault.
Every so often I turn the key and get absolutely nothing from the starter, not even the faintest click. After a lot of messing about, a hot start kit, a new starter and some extensive testing, the fault seems to be within the immobiliser unit. Carl explained the immobiliser relays were wired incorrectly by TVR which doesn't help the situation and the hot start kit I fitted may not improve my situation if these relays are past their best. While I am saving up the pennies for Carl to put a new upgraded alarm system on the car I figured a quick fix to temporarily get around the fault would be to simply bypass the immobiliser on the ignition circuit.
Now I know some of you have already done this so I would be grateful one of you kindly PM me with how you configured your wiring. I simply want to turn the key and know the car will start, the immobiliser still controls the live feed to the fuel pump so the car will remain secure. Thanks in advance to anyone that can PM me the details. Edited by Chimpafrolic on Tuesday 7th June BrianMillar posts months.

how to reset saab 9-5 arc theft alarm
I may be wrong but doesnt the little plug-in fob thing by the ignition lock bypass the immobiliser or does it still need the relays etc working. OK so I did the surgery yesterday, after a bit of testing with a meter the bypass actually required no additional wiring. Taking great care to ensure the changes are completely reversible I eliminated the involvement of the Meta immobiliser on the starter solenoid circuit to establish if it would solve my annoying intermittent starting fault.
Once the correct wires were traced and the circuit was understood it was an amazingly simple job to eliminate the immobiliser on the circuit that energises the starter motor solenoid.
It ended up being a really neat and simple connection that involved very little invasive surgery of the loom, pleasingly it also retains the hot start relay to protect the contacts within the ignition switch in the start position. Recently the starting fault had become so bad almost every time I have tried to start the engine I got absolutely nothing with the key in the start position.
Well I have now extensively tested the car's ability to start both hot and cold and so far my bypass seems to have completely resolved the problem. In fact the Prestolite starter sounds super smooth and has massive cranking power, way better than my condemned original which thinking about it is also likely to be without fault. This excellent Prestolite starter is available from Brookwell Land Rover Parts at a very reasonable price. Many thanks to everyone that helped me and in turn I hope my experiences help others with this fault and stops them spending unnecessarily like I did.Clear linux review
But for now my solution cost me nothing more than a few connectors and an hour of my time, it's completely reversible and because the immobiliser still controls the live feed to the fuel pump the car's security is in no way compromised.
I call that a result PS: If I want to, it's now possible to crank the engine on the starter without fuel, so perfect for bring the oil pressure up without starting the engine after an oil change.
