ISTA+ ABS Bleed

boba7523 · 01-07-2024, 09:02 PM

Hi guys,

I'm wondering if I need a voltage regulator hooked to the battery when I perform ABS bleed procedure through ISTA+.

Or can I just just charge the battery to 100% before starting the procedure?

I've heard that ISTA+ can brick the car if there is sudden drop in voltage or something.....

Thank you!

I’ve seen it done with and without a battery charger. It’s not a very long process but, if you have the charger, just play it safe and do the procedure with the charger.
