Customer states theft light comes on and has to wait 10min until it resets and turns back on. I checked it and seems 5volts are active when the theft kicks in. Once it reads it it drops to 4.4 vlts come to find the ignition switch is faulty which causes the signal to not be sent to the pcm at times. I will keep you posted if truck comes back. After ignition switch replacement truck turns on perfectly.
