    Just to activate. I got close to the wall in the garage and it activated at the exact same spot it always does. Then I pulled put of the garage on an angle getting close to the garage wall and that tone activated. Do you think I may need further calibration??

    OBDII scanner and memory saver have nothing to do with each other except that you plug them into the same port. Two totally different devices. See @Mendel Leisk's link in post #77. That one looks just like my memory saver. They are readily available in auto parts stores.

    This question is better asked on a medical forum, not an automotive one.

    Has anyone tried the H4 battery from Pep Boys has on sale for $100 + taxes? The specs are the same as my battery in a 2017.

    This is an older thread, but I have in my 2017. Plus I didn’t do any of the rituals stated in the OP. On the first start, all my sensors stopped working, which I was happy with, but everything came back after restarting 30 minutes later.


    iPhone ?

    I found my 12v battery was discharged because of the boot light being left on. Completely flat after little driving during covid, I couldn't open the door with the remote. I've charged countless batteries before so I disconnected the battery for charging to avoid any possibility of damage to electronics. Then reconnected battery, Car started fine and drives OK except none of the heating system controls are functional! A unit on top of the engine is humming all the time. I also have a message: IPA System Check Visit your dealer.
    Trouble is - the dealer is closed for covid - I've left a message and hope they will get back to me soon.

    Any advice on what I can do to fix this myself? I've read all the stuff about fuel caps and driving in a straight line but nothing corresponds to my problem. It seems that the system might need a reset. Just hoping it's nothing expensive. I can't believe that changing a 12v battery can be so complicated!

    A weak 12 volt battery can confuse computers and give strange codes. Replace the 12 volt battery first before anything else. They generally do not work well after being run down.

    A new 12 volt battery is cheap insurance
