First new here. Thanks for accepting 🙏🏽 Have an MK7 2014.
Recently got hit with an ABS light. Error u3003-16.
“Battery voltage below threshold”. My climate control module will turn on for a second and the number display turns right off. I have no air at all
Just got the multimeter and checking through fuse everything seems to be fine. Continuity through it all and nothing blown.
I tried replacing the CCM, but did the same thing. Turns on for a second, and then goes off.
I purchased a brand new battery, but nothing. Still same “low voltage”. I sanded down the terminals connecting to the battery and nothing. I tested the terminals from the battery and gets correct 12.45-12.5 amps. I’m no mechanic and this is driving me nuts
in the “secret menu” battery shows great voltage while cars on 138, 120 when cars in accessory mode.
My radio will also sometimes have volume, but sometimes I have to turn the car off, then start the car back up for the volume to come back up.
Next up is checking the relays but I’m not able to pull it because I can’t grab it -____- behind the fuse box.
if anyone has experienced something like this let me know.
