How to Diagnose and Solve B1475 Accessory Delay Relay Contact Short To Battery Issues

Introduction

If you’re experiencing issues with your car’s accessory delay relay, you may have encountered the B1475 error code. This code indicates that there is a short circuit in the accessory delay relay contact, which is causing the battery to drain. This can be a frustrating problem to deal with, but with the right tools and knowledge, you can diagnose and solve the issue on your own.

Step 1: Check the Battery

Before you start diagnosing the issue with the accessory delay relay, it’s important to check the battery. A weak or dead battery can cause a variety of electrical issues in your car, including the B1475 error code. Use a multimeter to check the voltage of your battery. If the voltage is low, you may need to replace the battery.

Step 2: Check the Accessory Delay Relay

Once you’ve ruled out the battery as the cause of the issue, it’s time to check the accessory delay relay. This relay is responsible for controlling the power to your car’s accessories, such as the radio and power windows. Start by locating the relay in your car’s fuse box. Use a multimeter to check the continuity of the relay. If the continuity is broken, you’ll need to replace the relay.

Step 3: Check the Wiring

If the accessory delay relay is functioning properly, the next step is to check the wiring. A short circuit in the wiring can cause the B1475 error code. Use a multimeter to check the resistance of the wiring. If the resistance is too low, there may be a short circuit in the wiring. Check the wiring for any signs of damage or wear. If you find any damaged wiring, you’ll need to replace it.

Step 4: Check the Fuse

If the wiring is in good condition, the next step is to check the fuse. A blown fuse can cause the B1475 error code. Locate the fuse for the accessory delay relay in your car’s fuse box. Use a multimeter to check the continuity of the fuse. If the continuity is broken, you’ll need to replace the fuse.

Step 5: Check the Ground Connection

If all of the previous steps have failed to solve the issue, the problem may be with the ground connection. A poor ground connection can cause a variety of electrical issues in your car, including the B1475 error code. Use a multimeter to check the resistance of the ground connection. If the resistance is too high, you may need to clean or replace the ground connection.

Conclusion

Dealing with the B1475 error code can be frustrating, but with the right tools and knowledge, you can diagnose and solve the issue on your own. By following these steps, you can identify the cause of the issue and take the necessary steps to fix it.
