Try asking for mode 1 message 0 - byte 1 is vats status:
Code:
1 0-2 UNIVERSAL THEFT DETERRENT STATE
0 = PASSIVE
1 = ACTIVE
2 = DOORS ARMED
3 = DOORS AND HATCH ARMED
4 = ALARM
5 = ALARM TIMED OUT
Or on my bench I connected a led to the security pin on C6. If it's lit solid with switched 12v on you've triggered vats. If so you'll need to remove the switched power (IGN) and leave it powered up on unswitched battery until the penalty period times out. That could be as long as 12-15 minutes. Double-check the vats resistor connections also.
You may have to trick it into passing vats by simulating a key-in, then applying power to E4. < Edit!
Another possibility is that it wants to see the left door switch triggered before key-on. I wonder if there's some mechanism involving word_1983 that changes the vats requirements. I know it worked on the test bench without any of the key-in or door open trickery, but that was after it had already passed vats while connected to my test bench PCM with said trickery.
