Have you worked on the restraint system before?

B0090 - Left Frontal Restraints Sensor

A B0090 trouble code refers to the restraint (seatbelt) sensor on the left front seat.

A B0090 DTC code may be caused by a wiring or connector fault, or restraint sensor failure.

To fix the problem, first check the wiring and connections leading to the left front restraint (seatbelt) sensor. If the wiring has no obvious problems, check the wiring using the specifications from a proper service manual. Verify operation of the sensor and replace if necessary.

Checked all writing connection visually-look like new! Seat belt retractor works fine. Replaced seat position sensor as well as left front impact sensor. Every think looks as good as new?
Expert:  Jeremy replied 1 year ago.

When you replaced those items, did you reset the SRS in the vehicle with the Ford IDS tool? The system needs to be reset and then it will calibrate to make sure those sensors are operating/reading properly. If you haven't done that, that is what you need to do before you can go further.

I cleared the codes with Snap on scanner?
Expert:  Jeremy replied 1 year ago.

Does the snap on have the SRS relearn on it? There is a spot in the Ford IDS where we have the SRS do a elearn and it scans all the sensors/modules and resets the system. I don't use the Snap On one so I'm not sure of the capabilities of it.

It does not have learn. I also upon checking have code B1211?
Expert:  Jeremy replied 1 year ago.

That code is for the seat belt retractor.

Was the harness tested?
