Silver LT Posted May 26, 2006 Report Share Posted May 26, 2006 (edited) Last night, I tried to install a new pcm. I attempted the security relearn process, twice, and the truck would not start (11 minutes on, 30 seconds off, 3 times). I disconnected the battery, both times, and the security light did turn off, about 3/4 of the way through the first round, both times. I am not sure what I am doing wrong. I reinstalled the original pcm, and it started first time, no relearn. Friday update - All fixed now. On the third time, it worked fine. I don't know what I did different, but glad it works now!

SS_bnoon_SS Posted May 26, 2006 Report Share Posted May 26, 2006 I had a little trouble with mine doing the relearn the first time. I think it was the "on, off, on" thing that threw me.. Glad you got it fixed!!! Quote Link to comment Share on other sites More sharing options...
SoCalSS Posted May 29, 2006 Report Share Posted May 29, 2006 when you turn it off you need to try and start the car before you start the process all over again. Most people turn off the car and dont try to start it Quote Link to comment Share on other sites More sharing options...
