My first post. 3 months trying to fix and still Airbag light on with DTC 809131 and 809631 RCM_d064_pasBPillarLeft and RCM_d061_pasBPillarRight. The RCM was damaged by rainwater. Nothing was deployed ever. Replaced RCM with a used one that was reset and a second one which never deployed anything. Same codes persist with airbag light on.
If I unplug the left side B pillar impact sensor I get a 3rd code 809231 RCM_d063_pasCPillarLeft. This sensor is on the left B pillar yet throws a left C pillar code. Strange. See attached photo. This is the sensor I unplugged and even tried a new one.
All wires , pins and plugs are clean with no corrosion. This was 3 inches or so of fresh rainwater for a short period of time, immediately vacuumed out and continued to drive the car.
Both seat modules got wet and were replaced. Both seats are working properly.
The Body Control Module BCM/BCU has corrosion on the bottom inch of the board and appears to be working properly except the Auto Present handles failed. I assume that circuit is on the bottom of the BCM that got wet. Still fobs and app key work fine.
Any help will be greatly appreciated.
