How to Fix B1352 Ignition Key-In Circuit Failure

Introduction

If you’re experiencing the B1352 Ignition Key-In Circuit Failure error code, you’re not alone. This error code is a common issue that many car owners face. The good news is that it’s a problem that can be fixed with a little bit of know-how and some basic tools. In this article, we’ll walk you through the steps to fix the B1352 Ignition Key-In Circuit Failure error code.

What is the B1352 Ignition Key-In Circuit Failure Error Code?

The B1352 Ignition Key-In Circuit Failure error code is a diagnostic trouble code (DTC) that indicates a problem with the ignition key-in circuit. This circuit is responsible for detecting when the key is inserted into the ignition and sending a signal to the engine control module (ECM). When this circuit fails, the ECM is unable to detect the key, which can prevent the engine from starting.

Step-by-Step Guide to Fixing the B1352 Ignition Key-In Circuit Failure Error Code

Step 1: Check the Key

The first step in fixing the B1352 Ignition Key-In Circuit Failure error code is to check the key. Make sure that the key is in good condition and that it’s not damaged or worn. If the key is damaged or worn, it may not be able to make proper contact with the ignition switch, which can cause the error code to appear.

Step 2: Check the Ignition Switch

The next step is to check the ignition switch. Use a multimeter to test the switch and make sure that it’s functioning properly. If the switch is faulty, it will need to be replaced.

Step 3: Check the Wiring

If the key and ignition switch are both in good condition, the next step is to check the wiring. Look for any damaged or corroded wires that may be causing the problem. Use a multimeter to test the wiring and make sure that it’s functioning properly. If there are any damaged or corroded wires, they will need to be repaired or replaced.

Step 4: Check the ECM

If the key, ignition switch, and wiring are all in good condition, the problem may be with the ECM. Use a diagnostic tool to check the ECM and make sure that it’s functioning properly. If the ECM is faulty, it will need to be replaced.

Useful Tips

– Always use a multimeter to test the key, ignition switch, wiring, and ECM.
– Make sure that you have the proper tools and equipment before attempting to fix the error code.
– If you’re not comfortable working on your car, it’s best to take it to a professional mechanic.
