VATS system help
I need some help doing the vats system relearn, it says to disable the headlights, is this a techy way of saying shut them off? Is this a duh stupid question?
The typical 1998+ Passkey relearn procedure is this:
1. Disable your headlamps. Attempt to start the vehicle. Vehicle may or may not 'fire' and quit. Some vehicles will not engage the starter. This is normal. DO NOT TURN OFF KEY YET !!
2. Leave the key in the "on" position, until the 'security' light goes out or quits alternately flashing between "Security" and "Battery". This relearn period always takes 10 minutes. How long does this take ? 10 minutes. How long do I have to wait ? 10 minutes.
3. After security light is no longer displayed, shut the key off ! Wait 5-10 seconds and repeat the above procedure (steps 1 through 3) another two completed times for a total of 3 start-relearn-attempts, remembering to shut the key off between each 10 minute relearn procedure. This will take 30 minutes--no less. If the 4th start attempt fails to start the vehicle you did one relearn step (or all of them incorrectly). If you left your headlamps on until the battery went dead and voltage dropped below 10.5 volts, no amount of relearn attempts will be learned !!
Don't read too much into this. Most people cannot seem to grasp the simplicity of this relearn procedure.

Not necessarily. If your battery is questionable, then headlights
or DRLs might kill your battery before the 10 minutes is up. If
you have a new battery or charger handy, then no worries.
