In this article, we’ll walk you through the steps you need to take to fix this issue and get your illuminated entry system working properly again.

What is B1371 Illuminated Entry Relay Circuit Failure?

B1371 is a diagnostic trouble code that indicates a problem with the illuminated entry relay circuit. This circuit is responsible for turning on the interior lights when you open the doors of your car. When this circuit fails, you may notice that your interior lights don’t turn on when you open the doors, or that they turn on and off intermittently.

Step-by-Step Guide to Fixing B1371 Illuminated Entry Relay Circuit Failure

Step 1: Check the Fuse

The first thing you should do when you’re experiencing issues with your illuminated entry system is to check the fuse. The fuse for the illuminated entry system is usually located in the fuse box under the dashboard or in the engine compartment. Check your owner’s manual to find the location of the fuse box and the specific fuse for the illuminated entry system. If the fuse is blown, replace it with a new one and see if that fixes the problem.

Step 2: Check the Relay

If the fuse is not the problem, the next thing you should check is the relay. The relay is responsible for sending power to the illuminated entry system when you open the doors. To check the relay, you’ll need to locate it in your car’s fuse box. Once you’ve found the relay, remove it and inspect it for any signs of damage or wear. If the relay looks damaged, replace it with a new one.

Step 3: Check the Wiring

If the fuse and relay are not the problem, the issue may be with the wiring. Check the wiring for any signs of damage or wear, such as frayed wires or loose connections. If you find any issues with the wiring, you’ll need to repair or replace the affected wires.

Step 4: Check the Door Switches

If the wiring is not the problem, the issue may be with the door switches. The door switches are responsible for sending a signal to the illuminated entry system when you open the doors. To check the door switches, you’ll need to remove the door panels and inspect the switches for any signs of damage or wear. If you find any issues with the door switches, you’ll need to replace them.
