Hey guys, i have a 01 gtp. i bought the car a few weeks ago. i read on line about the cat test the 01 and newer ones do. I wanted to remove my cat so took my 00 computer out and swapped it before i sold the 00 gtp. Every thing was working great. I flashed about 4-5 different tunes now.
Well last night i was looking through the tune on my HPT's. I changed a few fan settings and went to flash it in. All went well till this morning when i went to start it. the security light stayed on and car died after about 3-4 sec of running. I read this on an on hpt's forum about 'looking' at that Security window area in HPT's, and if you do that it some how changes something (they didnt say any more about it). Well I'm pretty sure thats what i did. I remember opening that window to just look at it (i didn't touch or change anything)! i cant find any more info on this "looking at that window then your screwed"...
will this work?
10. How do I perform a security relearn?
1. Disconnect battery
2. Install new computer
3. Reconnect battery
4. Put emergency brake on to disable daytime running lights (this step is required!)
5. Make sure all doors trunk and hood are closed leave driver window down and reach in threw window
6. Try to start. If it doesn't start, leave the key in the on position for 10 min on 97-03 cars and 15 min for 04 and newer cars. The security light should turn off after this amount of time.
7. Turn off ignition for 3 seconds
8. Try and start the car. It probably won't start. Repeat step 5 two more times.
9. If this doesn't work disconnect battery for 5 seconds and then try and start the car.
If that doesn't work, try this one:
1. Disconnect battery for 10 sec.
2. Reconnect battery
3. Turn key to ON position
4. Do not try to start vehicle, just quickly click to RUN position to engage security light
5. Let vehicle sit with key ON for 35 min.
6. Attempt to crank vehicle. Once vehicle is running, the security light may still be on
7. If security light is still on, turn key to OFF position for 5 sec.
8. Turn key to ON position and security light should turn off
9. Start vehicle and enjoy new PCM
Notes: If your car starts at any time and stays running, you are done. If your car starts and dies, try step 9. If it dies after 2 seconds after you have done these steps, you either have a bad FP resistor or the security setting in your PCM is wrong and it will need an update. Security relearn procedure will not work with the valet key!
