Introduction

If you own a car with a power sliding door, you may have encountered the B2374 error code. This code indicates a problem with the power sliding detent (latch) circuit, which can prevent the door from opening or closing properly. In this article, we will discuss how to diagnose and solve B2374 power sliding detent circuit failure issues.

What is the B2374 Error Code?

The B2374 error code is a diagnostic trouble code (DTC) that indicates a problem with the power sliding detent (latch) circuit.
