Dodge/Chrysler/Jeep OBD2 codes: Manufacturer-specific Code With Meaning/fault location.

Do you have a Dodge, Chrysler or Jeep that was made after 1996? Surely your car had an OBD2 system to control the emission of the vehicle.

The OBD2 system obviously has more advanced features than the first version – the OBD1, and it is also more standardize with the generic code, which is the same for all manufacturers. However, OBD1 and OBD2 are also sharing one characteristic – manufacturer code, which is set by the manufacturer of the vehicles.  Thus, it is essential to get proper knowledge about this type of code if you want to diagnose it.

This article will show you a list of Dodge/Chrysler/Jeep OBD2 codes with meaning/fault location. Having more knowledge about the codes will be beneficial for you when you want to fix your car. Let’s get going!

How To Check The Codes With Scan Tools

Before starting diagnosing your vehicle, the first thing that you need is an OBD2 scan tool. If you have other diagnostic equipment that usually work along with a computer or laptop, please make sure that your personal computer has installed the necessary software for the equipment. Here is a guide to check the OBD2 codes of your Dodge/Chrysler/Jeep car.

OBD2 scanner is a good tool to diagnose the codes
OBD2 scanning tool

Step 1: Locate the diagnostic connector/16-pin data connector (DLC). This thing usually installed under the dashboard near the brake pedal.

Step 2: Take off the cover of the connector

Step 3: Plugin your scan tool to the connector

Step 4: Turn on your car ignition. If your car has a stop/start buttons, there is no necessary to start the engine. You just need to double press the button without pressing the brake pedal. This will turn on the accessories and the OBD port

Step 5: The OBD2 scanner will immediately diagnose your car to find if there is any fault and show you the code. Read the instructions book that comes along with your scanner to read the codes. After having the code, you can take note of them and solve the problem by yourself with the help of other online information source or ask an expert mechanic to fix your vehicle

Final Thoughts

After reading this article, you may know all the meanings of every code you need. Please take note that this article is for information purposes only. To fix the problem, you ought to check the official website of the scanner or find some help from other mechanics.
