Using the PIN number and key to disable immobilizer

Dave, if you have any old Ferrari dealer reciepts, the code may be on that reciept. Some did put it on there incase of trouble. Take a look.

 

Dave- Here is how to do it in very plain English with a checklist.

The immobilizer sequence did not work for me either. I have my original code sheet although the numbers have faded a but since 1998 and therefore not 100% decipherable. I hope like hell I never need it. I will try to go back to the original dealer (Algar) again sometime soon to try and validate the numbers. Good luck and let us know of any success!

 

Dave, when I programed my new remotes I used 0-2-0 on the ignition switch.

My alarm ECU was changed early in the cars life and the PIN in the original paper work didn't work. I had to order the new code through dealer parts. $$$$

 

Dave- Never mind Ferrari's markings on the ignition switch. The cycle is off-on-off in less than two seconds for each number and then a five second pause (2-20 seconds works) between each number. I have done it and I wrote the document I attached and that you pulled from FL. The checklist should lead you right through the process. I wrote it with input from Brian Crall and others after reprogramming my alarm ECU to accept a new set of fobs Boardwalk sent me. Doing the engine start sequence is the first part of the reprogramming sequence. First I tried starting the engine and it worked on the first try. Then I reprogrammed the alarm ECU and that worked on the 2nd try.

You just have to be methodical.

 

Dave- Off means key in the ignition, but not turned on. Ferrari calls it stop or 0. On means with the ignition on, like it says in the owners manual, and Ferrari also calls it II. Trying any other combination is a waste of time.

Try following the checklist after reviewing it first. Most people take too long on the off-on-off cycle for each digit of the number you are entering. It needs to be done just about as fast as you can do it. Talk out loud to yourself. It helps.

 

Did not see this post so accidently posted same thing today. Just to clarify 0 is key in ignition but you could pull it out. Is that right?

 

Grant- Correct.

 

Thanks Terry will have to try it again. Maybe I was pausing to long for the digits. I did get the red remote and the two black ones programmed after about an hour. Tried to do it again though and it never worked. Gave up after about 3 hours of off and on testing. Figured I was probably going to wear the ignition out before I figured what I was doing wrong.

 

Grant- Once the new PIN is programmed into the alarm ECU, the LED will never speed up its flashing again because it already has that PIN. Engine start should be no sweat, though, if you got the hard part done. The hard part is programming the alarm ECU with the new set of fobs after you essentially went through the engine start procedure to get there.

 

Dave I think Terry was describing once I got the new pin into the alarm ecu. Thanks terry. I did get everything working. What I was trying to do after was just start the car by using the ignition to put the pin in. I wanted to know how to do it in case on a trip my fob quit working and my spare fobs were at home. This is what I will be trying to do when I get back to California.

 

Dave- Lock your car with the remote every time you get out, even to get gas. Then you will have to use your remote to get in and you will have 2 minutes (120 seconds) to start her before the immobilizer rearms. Easier than fiddling with the pushbutton while it is hanging from the ignition.

 

Dave- As soon as you open the door, the system is pressurizing and it only takes a few seconds. By the time the check ok lamp illuminates, she is ready to go.

 

Dave- Unless the F355 is different from all the other F1 cars, it pressurizes as soon as you open the door. You should be able to hear it. The system needs to be pressurized so you can put it into neutral for start.

There are some differences in the F355 vs later F1 cars. If you do not put your foot on the brake for 4 seconds when stopped and in gear, the system will select neutral for you. It is 90 seconds for later cars.
