Introduction

If you’re experiencing the B1374 illuminated entry relay short to ground error code, you’re not alone. This is a common issue that many car owners face, and it can be frustrating to deal with. However, with the right tools and knowledge, you can fix this problem yourself and save money on costly repairs. In this article, we’ll provide you with step-by-step instructions on how to fix the B1374 illuminated entry relay short to ground error code.

What is the B1374 Illuminated Entry Relay Short to Ground Error Code?

The B1374 error code is related to the illuminated entry relay in your car. This relay is responsible for turning on the interior lights when you open the door. When the relay is shorted to ground, it means that there is a problem with the electrical circuit that controls the relay. This can cause the interior lights to stay on even when the doors are closed, which can drain your car’s battery.

Tools You’ll Need

Before you start fixing the B1374 error code, you’ll need to gather a few tools. Here’s what you’ll need:

• Socket set
• Multimeter
• Wire strippers
• Electrical tape
• Soldering iron
• Solder

Step-by-Step Guide to Fixing the B1374 Error Code

Now that you have your tools ready, let’s get started on fixing the B1374 error code. Follow these steps:

Step 1: Disconnect the Battery

The first step is to disconnect the battery from your car. This will prevent any electrical shocks or damage to your car’s electrical system. Use a socket set to remove the negative cable from the battery.

Step 2: Locate the Illuminated Entry Relay

The illuminated entry relay is usually located in the fuse box under the hood of your car. Consult your car’s manual to find the exact location of the relay.
