2009 HONDA CIVIC FAULTY POWER SUPPLY (VB LINE)

[slavax]

Hello there,
I need some help here please. This civic came in with DTC A2-10 Faulty power supply (VB line)

Does any one know how to fix this?
I already checked the fuses and tried a different module that I know us good. Same error keeps popping up.

Thank you!!

did you test for power supply at srs module connector?

Check the pins on the connector , maybe they are bent

from the position of looking at the pins in the module - The VB pin will be the second bottom left pin. So if you are counting the bottom row from left to right , it will be bottom left lower pin #2 . Check the power coming to that pin, should be battery voltage .

I was putting this car on a side for a long time and finally was able to work on it.

1. I printed out a diagram from ProDemand and located the VB Line pin on the module plug.
2. Located test point (10A fuse) on the back side of the fuse box.
3. Checked the voltage and continuity.... nothing!
4. I ran my own VB Line, solder everything together and BOOM!, fixed the problem.

Thank you ALL for help, especially sbkracer1 for pointing me into the right direction!!!
