When the dreaded check engine light turns on, you hold your breath and hope something simple like an oil change resolves the problem, but it is sometimes far more serious. For Ford vehicles, a Ford IDS (Integrated Diagnostic System) helps auto mechanics identify those serious problems. The Ford IDS scan tool connects to the vehicle's computer and produces a code that matches the component in need of repair. A computer program translates the code and provides information about possible solutions. When simple adjustments like refilling fluids and changing the oil do not do the trick, this diagnostic tool takes the guesswork out of automobile repairs and is essential for anyone who regularly works on Ford and Lincoln vehicles. Available on eBay, the Ford IDS tool diagnoses issues for current and past Ford and Lincoln models and comes with a USB cord for easy connection to any PC. A complete kit includes the scan tool, the software disk, cables, and a laptop PC. Additionally, the VCM scanning tool requires installation of the IDS software on a computer to work.
