How to Fix B1354 Ignition Key-In Circuit Short to Ground

Introduction

If you’re experiencing the B1354 error code on your car, it means that there’s a short circuit in the ignition key-in circuit. This can be a frustrating problem to deal with, but fortunately, it’s not too difficult to fix. In this article, we’ll walk you through the steps you need to take to get your car back up and running.

Step 1: Check the Wiring

The first thing you should do when you encounter the B1354 error code is to check the wiring. Look for any signs of damage or wear, such as frayed wires or loose connections. If you find any issues, you’ll need to repair or replace the affected wiring.

Step 1.1: Disconnect the Battery

Before you start working on the wiring, it’s important to disconnect the battery. This will prevent any electrical shocks or damage to your car’s electrical system.

Step 1.2: Inspect the Wiring

Once the battery is disconnected, inspect the wiring for any signs of damage or wear. Look for frayed wires, loose connections, or any other issues that could be causing the short circuit.

Step 1.3: Repair or Replace the Wiring

If you find any issues with the wiring, you’ll need to repair or replace the affected wires. This may involve soldering new wires in place or replacing damaged connectors.

Step 2: Check the Ignition Switch

If the wiring looks fine, the next thing you should check is the ignition switch. This is the component that sends the signal to the car’s computer that the key is in the ignition.

Step 2.1: Remove the Ignition Switch

To check the ignition switch, you’ll need to remove it from the car. This may involve removing the steering column cover or other components to access the switch.

Step 2.2: Test the Ignition Switch

Once you have the ignition switch removed, you can test it with a multimeter. Check for continuity between the switch’s terminals when the key is turned to the “on” position. If there’s no continuity, the switch may be faulty and will need to be replaced.

Step 3: Check the Key Cylinder

If the wiring and ignition switch both look fine, the next thing you should check is the key cylinder. This is the component that the key fits into when you start the car.

Step 3.1: Remove the Key Cylinder

To check the key cylinder, you’ll need to remove it from the car. This may involve removing the steering column cover or other components to access the cylinder.

Step 3.2: Test the Key Cylinder

Once you have the key cylinder removed, you can test it with a multimeter. Check for continuity between the cylinder’s terminals when the key is turned to the “on” position. If there’s no continuity, the cylinder may be faulty and will need to be replaced.

Conclusion

Fixing the B1354 error code may seem daunting at first, but with a little patience and some basic tools, you can get your car back up and running in no time. Remember to always disconnect the battery before working on any electrical components, and be sure to check the wiring, ignition switch, and key cylinder for any issues.
