i know this is in the wrong section but im trying to get some help here

this evening i installed my tune from nelson, after install i go to start my truck

truck throws the crank/cam relearn which i have a scanner for but what i dont know what its doing is throwing a service theft deterrent system.

to this i have no clue, can anyone help me out here?

 

Sounds like you need the security relearn, I thought that the tune came with instructions on how to do that...I'll see if I can dig it up. Moving this to a different section also...

 

yeah i figured it was going to get moved, i figured i would get more help in here than i would in another section. so thats why i posted it. but please if you could help me out here getting those instructions that would be greatly appreciated!

 

Yea, that's why I moved it here instead of the tuning section, figured that you'd get more hits

Anyway, I copied and pasted this off of Nelson's website:

1. Insert key, attempt to start the vehicle and leave the key in the ON position.
In some vehicles, the Battery and Security light will blink for several seconds, and then shut off. Then the Security light will then remain ON. Leave the ignition ON until the Security light goes OFF. This will take more than 5 mins.
2. When the Security light goes OFF, turn the ignition to the OFF position.
Leave ignition OFF for 20 Seconds.
3. Attempt to start the vehicle again and leave the key in the ON position.
In some vehicles, the Battery and Security light will blink for several seconds, and then shut off. Then the Security light will then remain ON. Leave the ignition ON until the Security light goes OFF. This will take more than 5 mins.
4. Turn the ignition to the OFF position for 20 Seconds.
5. Attempt to start the vehicle again and leave the key in the ON position.
In some vehicles, the Battery and Security light will blink for several seconds, and then shut off. Then the Security light will then remain ON. Leave the ignition ON until the Security light goes OFF. This will take more than 5 mins.
6. Once this entire procedure has been completed (three times) your vehicle will start on the fourth attempt.

Note: Some vehicles perform the relearn in a different sequence. You may notice your security light, battery light and abs light will alternate. Once the security light is left out of the sequence that is considered one step. Repeat the procedure two more times and on the fourth time your vehicle will start.

IIRC, the first time I swapped in a tuned PCM, I attempted to start it and left the key on for 11 min, then repeated that twice, and on the 4th attempt cranked and started the truck

 

thank you for doing some research for me! im going to go attempt that right now.

 

Glad to help, hope it works!
