Viper 5806V missing shutoff switch

So, I've completed all these steps as you've advised and how the manual instructs. I connected the tach wires W2W and learned the tach again. It indicated the tach was learned from W2W by flashing the parking lights only once. It still only starts for approximately 10 seconds and then shuts off. When I check the remote start diagnostic it flashes three times and four times.

Start engine, within 5 seconds hold the button on the control centre, BLUE light will come on and STAY on. That's how you learn tach. 10 second run tells me tach hasn't been learned!
