You’ve likely found yourself here because you’re a proud owner of a classic 1989 Jeep Cherokee (XJ), and you’re starting to delve into the world of diagnostics. Maybe your Check Engine light is glaring at you, or perhaps you’re just the proactive type who likes to stay ahead of potential issues. Whatever your reason, understanding how to use an OBD scanner on your vintage Jeep can seem like a daunting task. Don’t worry, we’re here to break it down for you.
Understanding the Question: What Does an OBD Scanner Do?
Before we dive into the specifics of a 1989 Jeep Cherokee, let’s clarify what an OBD scanner is and what it does. OBD stands for “On-Board Diagnostics,” and an OBD scanner is a device that connects to your vehicle’s computer system to retrieve diagnostic information. Think of it as a window into your Jeep’s electronic brain.
From a mechanic’s perspective, Mark Stevenson, author of “Automotive Diagnostics: A Comprehensive Guide,” states, “OBD scanners are essential tools for understanding and resolving vehicle issues. They provide valuable data about engine performance, emissions, and other critical systems.”
The 1989 Jeep Cherokee: A Pre-OBD-II Vehicle
Here’s the catch with your 1989 Jeep Cherokee: it predates the standardized OBD-II protocol, which wasn’t widely adopted until 1996. This means you won’t find a standard 16-pin OBD-II connector under your dash.
So, What Options Do You Have?
- Consult the Factory Service Manual: Your Cherokee’s service manual is your best friend. It will detail the specific diagnostic connector location and the procedures for retrieving trouble codes.
- Aftermarket Scan Tools: Several companies specialize in diagnostic tools for older vehicles. These tools might connect through the cigarette lighter or require a specific adapter for your Jeep’s diagnostic port.
- Check Engine Light Codes: Your Cherokee likely uses a combination of flashing Check Engine lights and other dashboard indicators to signal issues. Again, refer to your service manual to decipher these codes.
Common Questions About 1989 Jeep Cherokee Scanners

Unlike later models, the 1989 Cherokee doesn’t have a universal OBD-II port. The diagnostic connector is typically found under the hood, often near the fuse box or firewall.
Can I use a regular OBD2 scanner on a 1989 Jeep Cherokee?
No, a standard OBD-II scanner won’t work on your 1989 Cherokee. You’ll need a tool specifically designed for pre-OBD-II vehicles or consult your factory service manual for diagnostic procedures.
What kind of scanner do I need for a 1989 Jeep?
You’ll want to look for scanners or code readers that explicitly mention compatibility with 1989 Jeep Cherokees or pre-OBD-II Chrysler vehicles.
