If you arm the system, wait 25 seconds, then ground the middle pin of the 3 pin shock sensor port what does the evo do? what does the vehicle do?

I tried that even with up to 5 minutes of waiting inside the car everything works perfect if I open doors, truck hood, everything triggers  except nothing happens with impact sensor middle input directly to ground

Maybe try resetting the starter then re enabling the options for the alarm feature and re testing?

Page 2 of the guide.

Well that's the other problem I forgot to mention the sequence of resetting as follows below  nothing happens I don't get the red led under the yellow loop  to flash at all 


  1. turn ignition on
  2. press and hold valet switch until parking lights turn on (or red led under the vellow loop begins to flash)
  3. press and release the valet switch 23 times
  4. press and release the brake pedal once
  5. press and hold valet switch for 5 seconds. Pakring lights will flash to confirm.
  6. turn the ignition off (park lights will flash 4 times to confirm exiting programming).
press unlock on the oem remote before trying the reset
