The code B1237 for the Honda Civic will indicate that Your passenger side air mix control motor is having issues. Some of the symptoms that You will notice is the engine light illuminated as well as the air control mix motor is not working properly. Some of the possible causes for the issue are a faulty passenger side air mix motor, motor wiring harness is shorted or damaged, poor electrical connection at the circuit or a faulty climate control unit. It can be hard to pinpoint these issues and You will have to do some inspecting as well as trial and error to find out what it could be.

Are you guys sure you are giving accurate information? The B1237 has nothing to do with airbags,. It means "Maintenance Needed Soon". Each number corresponds with the type of maintenance needed. The 1 is for oil change. Basically, the car is recommending you get Engine Oil & Filter Change, Replace Fuel Filter, and tire rotation. My guess is you are probably coming up on 60k miles or one of those milestones that require additional maintenance.

What it means is time to do maintenance, code B on page 166 of the 2020 owners manual guide give you the specifics of the maintenance main items to be done.The numbers are also indicators of what specifically needs to be done. Thats on page 167
