How to Diagnose and Solve B1673 Seat Driver Occupied Input Circuit Open Issues

Introduction

If you own a car, you know how frustrating it can be when the check engine light comes on. One of the most common issues that can trigger this warning is the B1673 Seat Driver Occupied Input Circuit Open issue. This problem can be caused by a variety of factors, including faulty wiring, a malfunctioning sensor, or a damaged seat. In this article, we will guide you through the process of diagnosing and solving this issue.

Step 1: Check the Wiring

The first step in diagnosing the B1673 Seat Driver Occupied Input Circuit Open issue is to check the wiring. Start by inspecting the wiring harness that connects the seat sensor to the car’s computer. Look for any signs of damage, such as frayed wires or loose connections. If you find any issues, repair or replace the wiring as necessary.

Step 2: Check the Sensor

If the wiring appears to be in good condition, the next step is to check the sensor itself. Start by disconnecting the sensor from the wiring harness. Use a multimeter to test the resistance of the sensor. The resistance should be within the manufacturer’s specified range. If the resistance is outside of this range, the sensor is faulty and needs to be replaced.

Step 3: Check the Seat

If the wiring and sensor appear to be in good condition, the next step is to check the seat itself. Start by inspecting the seat for any signs of damage, such as tears or holes. If you find any issues, repair or replace the seat as necessary. Next, check the seat occupancy sensor. This sensor is located in the seat cushion and detects whether someone is sitting in the seat. Use a multimeter to test the resistance of the sensor. The resistance should be within the manufacturer’s specified range. If the resistance is outside of this range, the sensor is faulty and needs to be replaced.

Step 4: Reset the Computer

If all of the above steps have been completed and the issue still persists, the next step is to reset the car’s computer. This can be done by disconnecting the battery for a few minutes. Once the battery is reconnected, start the car and see if the issue has been resolved.
