Maintaining your 2008 Chrysler Town & Country in top condition requires understanding its electrical system, and a crucial component is the fuse box. Fuses protect your vehicle’s electrical circuits from overloads, and knowing the correct fuse for each system, especially the OBD2 port, is vital for diagnostics and repairs. This guide provides a detailed look at the fuse box diagram of your 2008 Chrysler Town & Country, focusing on the fuse related to the On-Board Diagnostics II (OBD2) port.
Understanding the Fuse Box of Your 2008 Chrysler Town & Country
Your 2008 Chrysler Town & Country utilizes fuses to safeguard various electrical components. When an electrical issue arises, checking the fuses is often the first and simplest step in troubleshooting. Knowing the location and function of each fuse can save you time and money on repairs.
Location of the Fuse Box
The primary fuse box in your 2008 Chrysler Town & Country is typically located under the hood. Consult your owner’s manual for the exact location, as it might slightly vary. Accessing the fuse box usually involves releasing a few clips or latches on a protective cover.
Fuse Types Used
The fuse box in your vehicle uses different types of fuses, including:
- FMX/JCase Fuses: These are high-current fuses, often used for critical systems requiring significant power.
- MINI Fuses: These are smaller, blade-type fuses used for lower-current circuits.
It’s important to replace a blown fuse with the same type and amperage rating to ensure proper circuit protection.

Finding the Fuse for the OBD2 Port
Based on the fuse diagram, the fuse associated with the OBD2 port in your 2008 Chrysler Town & Country is Fuse M28. It is a 10A MINI fuse. The description for Fuse M28 includes “J1962,” which is the standard connector specification for OBD2 diagnostic ports. This fuse protects the power supply to your vehicle’s diagnostic system.
What to Do If Your OBD2 Port Isn’t Working
If you are experiencing issues with your OBD2 port, such as a scan tool not powering on or failing to communicate with your vehicle’s computer, checking Fuse M28 should be one of your first steps.
- Locate the Fuse Box: Refer to your owner’s manual for the under-hood fuse box location.
- Identify Fuse M28: Use the diagram above or the diagram printed on the fuse box cover to find the M28 position.
- Inspect the Fuse: Carefully remove the fuse using a fuse puller (usually found in the fuse box). Check if the fuse wire is broken or burnt.
- Replace the Fuse: If the fuse is blown, replace it with a new 10A MINI fuse. Never use a fuse with a higher amperage rating.
- Test the OBD2 Port: After replacing the fuse, try using your OBD2 scan tool again to see if the port is now functioning.
If replacing Fuse M28 does not resolve the issue, there might be other problems such as wiring issues, a faulty OBD2 port, or problems with the vehicle’s computer system. In such cases, it is recommended to consult a qualified mechanic.
Conclusion
Understanding the fuse box diagram of your 2008 Chrysler Town & Country, especially knowing the fuse for the OBD2 port (Fuse M28), is a valuable skill for any car owner. Regularly checking your fuses and replacing blown ones with the correct type and rating can help maintain your vehicle’s electrical system and ensure your OBD2 port is ready for any necessary diagnostics. Remember to always consult your owner’s manual for the most accurate and vehicle-specific information.
