Lots of servos in these trucks!
Most of the vehicle electrics are still working.
Interestingly, the ignition switch, when turned to the "on" position will now allow the windows to operate, the gauges to come alive and the heater to work whereas before, none of this was possible. That result is through no effort on my part.
That said, I would think that the ALDL is active. Easy enough to test I suppose.
And if the Tech 2 will allow me to operate devices as you describe, that's the kind of tool I'm looking for.
(For the record, I'm an industrial automation electrician. Robots and servos and equipment like that. But troubleshooting a modern vehicle without tools or drawings? Forget about it!)
Thanks for the input.
