The Ford NGS (New Generation Star) scan tool, while outdated for newer vehicles, remains a powerful diagnostic solution for legacy Ford, Lincoln, and Mercury models (and some Mazdas). This comprehensive guide explores the capabilities of the Ford Ngs Card For Obd2 and why it’s a valuable tool for owners of older Ford vehicles.
Understanding the Ford NGS Scan Tool
The NGS was developed by Hickok Instruments for Ford and utilizes PCMCIA cards for service and diagnostics. Its software, specifically designed for Ford vehicles, covers a 25-year period, from the 1984 Lincoln Mark VII EEC IV system to 2009 models. This makes it exceptionally useful for diagnosing vehicles with varying GVWRs (Gross Vehicle Weight Ratings), including motorhomes based on the F-53 chassis, which often exceed the typical weight classifications of standard passenger vehicles. Different GVWRs often mean different PCM (Powertrain Control Module) calibrations and emissions classifications.
A key advantage of the NGS is its comprehensive functionality. Unlike some aftermarket tools that may not recognize specific fault codes due to proprietary calibrations, the NGS provides in-depth access to all system diagnostics. This is particularly important for addressing emissions-related faults, which are mandated by federal law to be open source. While newer generic OBD2 scanners might indicate a problem, the NGS offers the detailed information needed for accurate diagnosis and repair, often referenced in Ford factory service manuals of that era.
Why Choose the Ford NGS Card for OBD2?
The NGS scan tool offers several benefits for owners of older Ford vehicles:
- Comprehensive Diagnostics: The NGS provides complete access to all vehicle systems and diagnostic trouble codes (DTCs), allowing for in-depth troubleshooting.
- Bidirectional Control: The NGS allows users to not only read codes but also command various vehicle components for testing purposes, offering a significant advantage over basic code readers.
- Standalone Operation: Unlike newer diagnostic systems that often require online connections or subscriptions, the NGS operates independently. This eliminates the need for ongoing fees or software updates.
- Dealership-Level Functionality: The NGS offers the same diagnostic capabilities found in Ford dealerships during its era, empowering owners to perform professional-level repairs. This includes accessing proprietary information specific to Ford’s systems and calibrations.
Finding and Using a Ford NGS Scan Tool
Used NGS scan tools and PCMCIA cards are often available on online marketplaces like eBay. While the initial investment might be higher than a basic code reader, the comprehensive functionality and standalone capability make it a valuable tool for dedicated Ford enthusiasts and DIY mechanics.
Ford’s Evolution in Diagnostic Systems
Ford’s diagnostic systems have evolved over the years:
- NGS (New Generation Star): The focus of this article, covering vehicles from 1984 to 2009.
- WDS (Worldwide Diagnostic System): The successor to NGS, offering broader coverage and more advanced features.
- IDS (Integrated Diagnostic System): Ford’s current system, requiring online connectivity and licensing for full functionality.
The NGS stands as a reliable and comprehensive diagnostic solution for legacy Ford vehicles. Its standalone operation, bidirectional control, and in-depth access to Ford-specific systems provide a significant advantage over generic OBD2 scanners for owners of these vehicles. It allows for a level of diagnosis and repair that often surpasses the capabilities of generic tools, providing valuable insights into the inner workings of older Ford models.
