.150 amp draining while off

Anyone know what the ISF should be draining while off. I am getting .150 amp while off, it seems a little high.

I am not sure if this normal or not but I would think there are few circuits and sensors that remain active even with the car off. Presumably the remote key approach circuitry and maybe a some other could account for this. I don't think150mA should be much of a burden on a fully charged healthy car battery.

For how long? Most cars stay active for a few minutes after the vehicle has been shut off, and take a while in order to go to "sleep" as it's called.

This was common back when I worked for volvo. However, if it's remaining even after the vehicle was asleep, then we would diagnose by narrowing it down to which circuit by pulling and re-installing fuses with your meter hooked up until you saw the draw go away. Much more common on older cars, although there's always a risk of a module communicating when it should be asleep.
