What Do Airbag Warning Lights and Error Codes B1630 and P3107 Mean?

It sounds like you've made some good progress by replacing the B pillar sensor, which helped eliminate the fault codes. Now that you’re left with just the airbag light on, there are a couple of things you can try. First, disconnect the negative battery cable and let it sit for about five minutes before reconnecting it. This can sometimes reset the system and turn off the airbag light. If that doesn’t work, it’s possible that the airbag control module is faulty. In that case, you might need to have it reflashed. If you have access to a different scanner, it’s worth trying that first to see if it can read any additional codes or provide more insight into the issue. If the new scanner doesn’t help, sending the module out for reflashing would be the next step. Keep in mind that the sensors need to communicate properly with each other, so if one is still malfunctioning, it could cause the airbag light to stay on. Hopefully, the reset procedure works, but if not, getting the control module checked out will be important for ensuring everything is functioning correctly.

Can you please try this. Remove the positive connector on your battery for 5 minutes and then after 5 minutes put it back make sure it is properly connected. Then start the car and then let it run for 15 minutes and see if the error code will still appear. I will be standing by for your updates. --- Any updates [REDACTED NAME]?

I will leave this page open and will wait for your response. Regards, [REDACTED NAME] --- We disconnected the battery cable for 5 minutes. We reconnected the cable and drove the car for 30 minutes. The red triangle, air bag light and other lights are still on. Please advise. --- Did you disconnect both cables or the positive cable only? --- If you just disconnected only the red connector on the battery try to disconnect the positive and the negative connector for 5 minutes and then connect it back again. And start it and drive it for 30 minutes and see what will be the result. I will be standing by. --- Following your instructions, we disconnected the positive cable only. --- I see. Try to disconnect both positive and negative connectors from the battery for 5 minutes and then connect it back again and then start it. Then let it idle for 30 minutes. Advise me what will be the result. I will be standing by. --- We disconnect the positive only like you instructed. We reconnected and drove 30 minutes. The red triangle, air bag, and other lights are still on. --- Try to disconnect both positive and negative connectors from the battery for 5 minutes and then connect it back again and then start it. Then let it idle for 30 minutes. Advise me what will be the result. I will be standing by. --- It will not idle, the gas engine will shut down after it runs a while unless you drive it. --- I see. After you disconnected the positive and negative and connect it back after 5 minutes drive it for 30 minutes. We need to wait for the computer to reboot and let's see what will be the result. --- Ok. We are test driving it now. --- Copy that. I will be standing by. --- Any updates [REDACTED NAME]? Standing by for your response. --- He is out driving..let me call him. --- Sure. I will be standing by. --- The red triangle and air bag light is still on. Would you like me to rescan it when it comes back? --- I realize this is a hard problem. I will tip you if you solve it. --- Yes have it rescan and see if you can clear the codes. If not advise me what error code will show after you scan it okay. I will leave this page open and will wait for your response. --- Ok... I will do that as soon as the car returns. --- Sure. And also one more thing, can you check the harness and the connector of the air bag you installed. Please see if it's properly seated and there is no resistance between the wire harness side connectors. --- The connector seems to be fine. To review, we have changed the LH seat with air bag, the LH curtain bag, and the LH B pillar sensor. The error codes we get are P3107 C1310 B1400 B1630. The B1630 says curtain RH side air bag sensor. The car was hit in the left B pillar. Does this mean the RH sensor may be bad? We did not replace that one. --- Disconnect the RH side air bag sensor and then connect it back again. If you will still be getting the same error code replace it. Are you sure with the C1310 error code? It seems can pull up this code. The B1400 this code is for the Driver door one touch relay. It might circuit short to battery. --- Before we hooked up the air bag, we did not have a C1310 code. The VSC light is on now...so I assume that goes to that. The code still exists so we are going to get another sensor tomorrow. --- Noted [REDACTED NAME]. Keep me posted okay. --- We switched the two side air bag sensors to see if we would get a code for the left sensor instead of the RH sensor. Nothing changed. The error codes we get are P3107 C1310 B1400 B1630. --- I apologize I won’t be able to offer you the most helpful answer on this issue.
