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
- Wire strippers
- Electrical tape
- Soldering iron
Step-by-Step Guide to Fixing the B1374 Error Code
