Customer Question

Battery keeps going dead. Draw with key off is 250-450mA and goes away after 1hr down to 40. F19 and F21 under hood kill the current and F7 in dash cuts to 210mA. Kinda stuck now.

Hello and thanks for choosing just answer. After an hour your draw goes down to 40ma is that correct?
Customer: replied 1 year ago.
Yes

Thank you. 200-400 ma is pretty normal when modules are awake. Once they go to sleep if your draw is 60ma or less this is considered normal. If this is your reading I would suspect your battery is to blame. I would have the battery load tested. Your battery might pass anything other than a load test which is starting to become an outdated test. It works very well though.
You want a excellent 5 star answer & I would like to be rated the same for providing it. Consider I don't know your skill level & I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies. Try your best to respond with good detail so I can do the same. A rating is required. Your rating me, what I type. I am not an employee of this website, nor have control over the fees or the time it took to get a response. If you rate negative or not at all you still paid, but I get nothing. I want you pleased with me and my efforts, so let me know if your experience here has come up short.
