Introduction

In this article, we will be discussing the intricacies of dealing with Chrysler computers and programming. Chrysler vehicles have unique security features that can sometimes cause issues when it comes to replacing or reprogramming their computers. We will delve into the challenges faced by technicians when working with Chrysler computers and explore solutions to overcome these hurdles. So, whether you are a Chrysler owner or a technician working in the automotive industry, this article will provide valuable insights into the world of Chrysler computer programming.

The Issue with Chrysler Computers

Chrysler vehicles have a distinct computer system that can be complex to work with. One common problem that technicians encounter is when a replaced computer causes the car to start and then immediately shut down. This issue is often caused by the security feature in Chrysler computers not being properly addressed during programming. If the computer is from a security-enabled car and is installed in a non-security car or vice versa, the security feature may not align properly, leading to this frustrating problem.

How to Identify Security and Non-Security Computers

To avoid compatibility issues when buying a replacement Chrysler computer, it is crucial to identify whether it is a security or non-security computer. This information can be determined by the type of key the car uses. A black key indicates a non-security car, while a gray key signifies a security-enabled car. When purchasing a used Chrysler computer, it is advisable to obtain the exact part number to ensure compatibility with the vehicle.

The Importance of Part Numbers in Chrysler Computers

Part numbers are vital when it comes to purchasing replacement Chrysler computers. Having the correct part number ensures that the computer is compatible with the vehicle's systems. When inspecting the computer, look for the part number, which can usually be found on the casing. For example, the part number P56041801AD corresponds to a specific type of Chrysler computer. By matching the exact part number, you can ensure that the replacement computer will function seamlessly in the vehicle.

Clearing the Security on Chrysler Computers

When dealing with security-enabled Chrysler computers, clearing the security feature is essential for proper programming and functionality. Clearing the security can be done by connecting the computer to a bench setup and performing a reset. This process involves removing the computer from the vehicle, hooking it up to a bench setup, and clearing the security feature using specialized tools. Once the security is cleared, the computer can be reprogrammed with the appropriate vehicle identification number (VIN) and security status.

Programming Chrysler Computers on the Bench

Programming Chrysler computers on the bench provides a controlled environment for efficient and effective programming. By removing the computer from the vehicle and connecting it to a bench setup, technicians can ensure a seamless programming process. It is crucial to follow the correct procedures, including resetting the security and reprogramming the computer with the appropriate VIN and security status. Programming on the bench allows for thorough testing and troubleshooting before reinstalling the computer in the vehicle.

The Role of Skim Modules in Chrysler Vehicles

Skim modules play a significant role in the security system of Chrysler vehicles. The skim module is responsible for enabling or disabling the security feature in the computer. In some cases, a faulty skim module can cause security-related issues that affect the starting and running of the vehicle. If the issue is isolated to the skim module, disconnecting it and clearing the computer can bypass the security feature. However, this may trigger a warning light on the dashboard.

Replacing Skim Modules in Chrysler Vehicles

In situations where the skim module is faulty, replacing it may be necessary. When replacing the skim module, it is essential to program it with the appropriate PIN for the vehicle. This process typically involves connecting the new skim module to a bench setup and using specialized software to program it. Once programmed, the replacement skim module can be installed in the vehicle, allowing for proper functioning of the security system.

Tips for Programming Chrysler Computers

When programming Chrysler computers, it is crucial to follow certain tips and best practices to ensure successful results. Firstly, it is recommended to work with a reputable vendor when purchasing used Chrysler computers. This ensures the quality and compatibility of the replacements. Secondly, always confirm the security status of the computer and its compatibility with the vehicle before programming. Lastly, if in doubt or facing challenges, consult with an experienced technician or seek assistance from a professional programming service.

Conclusion

Dealing with Chrysler computers can be a complex task, especially when it comes to programming and security features. However, by understanding the intricacies of these computers and following proper procedures, technicians can overcome challenges and provide effective solutions. Whether it's identifying security vs. non-security computers, clearing the security feature, or programming on the bench, the knowledge and insights shared in this article will help technicians navigate the world of Chrysler computer programming with confidence.
