ADC Connection Failed

Hardware PCB

Hello, I have a problem with Micro V4.5 when i power 12v then teensy starts flashing red and wont show any data in AOG while in agio udp is connected imu,gps shows green. Then i looked at arduino serial monitor and saw: Start setup
SerialAOG, SerialRTK, SerialGPS and SerialGPS2 initialized

Starting AutoSteer…
ADC Connecton FAILED!
Autosteer disabled, GPS only mode

Starting Ethernet…
Initializing ethernet with static IP address
Ethernet cable is not connected - Who cares we will start ethernet anyway.

Ethernet status OK
IP set Manually: 192.168.8.120

Ethernet IP of module: 192.168.8.120
Ethernet sending to IP: 192.168.8.255
All data sending to port: 9999
Ethernet GPS UDP sending from port: 5120
Ethernet NTRIP UDP listening to port: 2233
Ethernet AutoSteer UDP listening to & send from port: 8888

Starting IMU…
CMPS not Connected or Found
0x4A BNO08X Ok.

useCMPS = 0
useBNO08x = 1

End setup, waiting for GPS…

Swapping GPS ports…
//When i powered 12v then this came//
$PANDA,0,00,99.99,11,-34,-127,0*6B

Then i checked continuity from teensy pin18 to that ads1115 empty sda header and got nothing same with scl, but from teensy to bno085 sda18 and scl19 had continuity. There was continuity from that empty ads1115 header sda to the 9th leg of the onboard ads1115 and scl to 10th leg.
Should i use jumpers from teensy 18,19 to that empty ads1115 header in order to try and connect it?

Hi

You mean orange?

You have the onboard ADS1115 soldered from JLCPCB?
5V on the WAS power circuit?

Yes orange, i looked at it with headlamp.
i do have 5v to the angle sensor and also i measured 5v from the(vdd,sda,scl) legs of the onboard 1115. i checked voltage from teensy SDA_LV, SCL_LV they are both around 3,2v.
i turned the board on without bno085 and cytron but still it says on serial monitor that ADC connection failed.
while agio shows green on the imu,steer,gps I dont see imu move when i turn the board but arduino serial monitor says bno ok.
I have no idea what to look for next.

Reheat the pins on the bno
Also check the underside of the pcb for any soldier shorts

Teensy pins were littlebit corroded and had solderballs on some pins and old caked flux was also there so i cleaned and resoldered them too with bno but nothing changed, arduino serial says that "ADC Connecton FAILED! " “bno ok”

I have no gps signal in my hangar so i drove outside and imu and WAS started working, everything is fine there was nothing wrong at all.
