Navigating the world of automotive diagnostics can be tricky, especially when dealing with vehicles from the mid-1990s, a period of significant transition in on-board diagnostics (OBD) standards. If you’re trying to diagnose an issue with your 1995 Jeep Cherokee and are searching for the right “1995 Cherokee Obd2 Adaptor,” you’ve come to the right place. This guide will clarify the diagnostic port locations on your 1995 Cherokee and help you understand which adaptor you might need.
Understanding OBD on a 1995 Jeep Cherokee
The 1995 model year is a crucial point in automotive history because it falls right on the cusp of the OBD1 and OBD2 implementation. OBD2 became mandatory in the United States for all cars in 1996, but some manufacturers, including Jeep, started incorporating OBD2 systems in some of their 1995 models. This transitional phase can lead to confusion when trying to locate the diagnostic port and determine the correct adaptor.
For a 1995 Jeep Cherokee, it’s essential to understand that it might have components of both OBD1 and OBD2 systems. This often means you won’t find a standard OBD2 port in the location you might expect in newer vehicles.
Locating the Diagnostic Ports on a 1995 Cherokee
Instead of a single, easily accessible OBD2 port typically found under the dashboard on the driver’s side in OBD2 compliant vehicles, the 1995 Jeep Cherokee can have multiple diagnostic connectors located in different areas. Based on the original forum discussion, here’s where you should look:
1. Engine PCM Diagnostic Port (Under the Hood):
For engine-related diagnostics, you’ll likely find a diagnostic port under the hood, near the Powertrain Control Module (PCM). This is often an OBD1-style connector. Look for a 6-pin pigtail coming directly from the PCM. This port is designed to read engine-specific codes.

2. Transmission, ABS, and Body Module Diagnostic Port (Under the Dash):
For diagnosing other systems like the transmission, Anti-lock Braking System (ABS), and body control module, there’s another diagnostic connector located inside the cabin. The original forum mentions it being “kind of behind the dash by the ashtray” on the driver’s side. This connector is described as a blue, 6-pin connector. It may be tucked up under the dash and possibly under the carpet in the driver’s side footwell area.

It’s important to note that these connectors are likely OBD1 style, even though you are searching for a “1995 cherokee obd2 adaptor.” The term “Chrysler diagnostic port” mentioned in the forum likely refers to these OBD1 style connectors used by Chrysler vehicles of that era.
OBD Adaptor Compatibility for a 1995 Cherokee
Given that your 1995 Jeep Cherokee likely uses OBD1 style diagnostic ports, a standard OBD2 adaptor will not directly plug into these connectors. You will likely need specific OBD1 adaptors designed for Chrysler or Jeep vehicles of the mid-1990s.
When considering a “1995 cherokee obd2 adaptor,” what you might actually need is an OBD1 to OBD2 adaptor cable or a scan tool that is compatible with OBD1 Chrysler vehicles. Some diagnostic scan tools come with interchangeable adaptors to accommodate both OBD1 and OBD2 vehicles.
Key Considerations for Adaptors:
- Check your scan tool compatibility: Before purchasing any adaptor, ensure your diagnostic scan tool is capable of reading OBD1 codes or is compatible with adaptors for older systems.
- Identify the connector type: Visually inspect the diagnostic ports in your Cherokee to confirm they are the 6-pin connectors described. This will help you select the correct adaptor type.
- Look for Chrysler/OBD1 specific adaptors: When searching for adaptors, specifically look for those listed as compatible with “Chrysler OBD1,” “Jeep OBD1,” or “mid-1990s Chrysler vehicles.”
Choosing the Right Adaptor and Scan Tool
To effectively diagnose your 1995 Jeep Cherokee, especially if you suspect transmission issues as mentioned in the original forum, you’ll need a scan tool and adaptor combination that can read the relevant systems through the available ports.
- For Engine Diagnostics: An OBD1 scan tool with a Chrysler OBD1 adaptor for the PCM connector under the hood should work for reading engine codes.
- For Transmission, ABS, and Body Systems: You will need a scan tool and adaptor compatible with the blue 6-pin connector under the dash. Ensure the scan tool can access these specific modules (transmission control module, ABS module, etc.). Basic OBD2 scan tools may not have the capability to read these older OBD1 systems, even with adaptors. You might need a professional-grade scan tool or a dedicated OBD1 scanner.
The forum user mentioned using a “Cornwell Tools Tech/Force diagnostic computer.” Professional scan tools like this often come with a range of adaptors for different vehicle makes and models, including older OBD1 systems. If you are using a similar professional tool, consult its manual for Chrysler OBD1 adaptor compatibility and instructions.
Conclusion
Diagnosing a 1995 Jeep Cherokee requires understanding its diagnostic system nuances. While you might be searching for a “1995 cherokee obd2 adaptor,” you likely need to focus on OBD1 adaptors compatible with Chrysler vehicles of that era. Locate the PCM connector under the hood and the blue connector under the dash. Choose a scan tool and adaptors that are specifically designed for OBD1 Chrysler systems to effectively diagnose issues with your 1995 Jeep Cherokee. Remember to always refer to your vehicle’s repair manual and your scan tool’s instructions for the most accurate diagnostic procedures.
