For owners of the rugged and reliable 1998 Jeep XJ, maintaining peak performance often involves a bit of DIY work. When that check engine light comes on, or you’re simply aiming for preventative maintenance, a quality scan tool becomes an indispensable part of your toolkit. But with so many options on the market, finding the best scan tool for a 1998 Jeep XJ can feel overwhelming. This guide, crafted by an experienced auto technician, will steer you through the options, focusing on tools that offer the best balance of capability and value for your classic Jeep.
Understanding Your 1998 Jeep XJ’s Diagnostic Needs
The 1998 Jeep XJ falls into the OBDII era of vehicle diagnostics. This means it has a standardized diagnostic port and uses a common communication protocol, making it compatible with a wide range of scan tools. However, not all scan tools are created equal. While basic code readers can tell you what is wrong by displaying error codes, they often lack the depth to truly diagnose why something is wrong. For a vehicle like the XJ, which might require more hands-on troubleshooting, you’ll want a scan tool that offers more than just basic code reading.
Snap-On Scanners: A Legacy of Quality for Older Jeeps
When it comes to professional-grade scan tools, Snap-On has long been an industry leader. While their newest, top-of-the-line scanners can come with a hefty price tag, their older models, especially those from the “Brick” (MT2500) and Solus series, have become surprisingly affordable on the used market. These older Snap-On scanners are particularly relevant for vehicles like the 1998 Jeep XJ because they were designed around the technology of that era and offer robust capabilities that often surpass modern budget scanners in certain areas.
The MT2500 “Brick”: An Affordable Powerhouse for 1998 XJs
An older Snap-On MT2500 “Brick” scanner, a cost-effective option for diagnosing 1998 Jeep XJs.
For the 1998 Jeep XJ owner looking for the best scan tool without breaking the bank, the Snap-On MT2500, affectionately known as the “Brick,” is an exceptional choice. These scanners, once the gold standard in professional garages, can now be found for around $150 or even less, complete with necessary cables and connectors. Don’t let its age fool you; the MT2500 is remarkably capable for older vehicles, including the 1998 Jeep XJ.
Key Advantages of the MT2500 for a 1998 Jeep XJ:
- Bi-directional Controls: This is where the MT2500 shines. Unlike many budget scanners that only read codes, the MT2500 offers bi-directional control. This means you can use the scanner to actively command vehicle components – like turning on the fuel pump, cycling the ABS pump, or testing individual sensors. This level of control is invaluable for pinpointing problems and performing thorough diagnostics.
- Transmission, ABS, and Airbag Support: The MT2500, even older models, can typically access and diagnose these crucial systems in a 1998 Jeep XJ. Many cheaper scanners are limited to engine and basic OBDII functions.
- Cost-Effectiveness: For the price, you get a level of functionality that is hard to match with new scanners in the same price range, especially for older vehicles. Cartridges with software up to 1999 are readily available and inexpensive, perfectly suited for a 1998 XJ.
- Ease of Use (for its era): While not as visually flashy as modern touchscreen scanners, the MT2500 is designed for professional use and is relatively straightforward to navigate once you understand its menu structure.
Stepping Up: Solus Series for Enhanced Features (Solus Pro, Ultra)

If your budget allows for a bit more investment, or if you also work on newer vehicles in addition to your 1998 Jeep XJ, consider a Snap-On Solus Pro or Solus Ultra scanner. These are newer models than the MT2500 and offer expanded capabilities and software.
Benefits of Solus Pro/Ultra for a 1998 Jeep XJ (and beyond):
- Wider Vehicle Coverage (especially newer vehicles): Solus scanners with updated software can handle a broader range of vehicles, including newer models. If you maintain multiple vehicles of different ages, this can be a significant advantage.
- Graphing Capabilities: Solus Pro and Ultra scanners offer graphing functions, which can be helpful for diagnosing intermittent issues or analyzing sensor data over time, for example, when troubleshooting fuel injection problems.
- Larger Screen and Interface: Solus scanners feature larger screens and more modern interfaces, often touchscreen, which some users may find more user-friendly than the MT2500’s older display.
- Software Updates: While older software is sufficient for a 1998 XJ, newer Solus scanners can be updated to support newer vehicle systems if needed in the future.
However, for the specific task of diagnosing a 1998 Jeep XJ, the additional features of a Solus might not be essential, and the MT2500 “Brick” remains a highly capable and more budget-friendly option. The core diagnostic and bi-directional functionalities relevant to a 1998 XJ are largely covered by the older MT2500 with appropriate software cartridges.
Key Features to Look For in a Scan Tool for a 1998 Jeep XJ
Regardless of whether you choose a Snap-On scanner or explore other brands, here are the key features to prioritize when selecting the best scan tool for your 1998 Jeep XJ:
- OBDII Compatibility: Ensure the scanner explicitly states it is OBDII compliant and supports 1998 vehicles.
- Bi-directional Controls: This is critical for in-depth diagnostics on an older vehicle. Verify the scanner offers bi-directional functionality for systems relevant to your Jeep.
- ABS, Airbag, and Transmission Diagnostics: If you want comprehensive coverage, confirm the scanner can access and diagnose these systems beyond just the engine.
- Live Data Streaming: The ability to view live sensor data is essential for understanding what’s happening in real-time as your engine runs.
- Reliable Brand Reputation: Especially when considering used tools, opting for a reputable brand like Snap-On, or researching other well-regarded brands, increases the likelihood of getting a durable and functional tool.
Making the Right Choice for Your 1998 Jeep XJ
Choosing the best scan tool for a 1998 Jeep XJ comes down to balancing your needs and budget. For owners primarily focused on their XJ and seeking maximum diagnostic power at an affordable price, a used Snap-On MT2500 “Brick” is an outstanding choice. It provides professional-level capabilities, including essential bi-directional controls, perfectly suited for the diagnostic needs of a 1998 Jeep XJ.
If you desire broader vehicle coverage for newer cars or appreciate more modern features like graphing and a touchscreen interface, a used Snap-On Solus Pro or Ultra is a worthwhile upgrade. However, for tackling issues specifically on your 1998 Jeep XJ, the MT2500 remains a surprisingly potent and budget-friendly option, making it a strong contender for the best scan tool for your needs. Investing in the right scan tool will empower you to maintain your 1998 Jeep XJ with confidence for years to come.
