For all car and light truck models manufactured since 1996. We take the mystery out of the Second-Generation On-Board Diagnostic system by showing you how to understand your vehicle's On-Board Diagnostic system. We show you how to deal with that 'Check Engine' light - from reading the code to diagnosing and fixing the problem. Includes information on diagnostic tools, powertrain management fundamentals, OBD-II 'monitors' and manufacturer-specific trouble codes for GM, Ford, Chrysler, Toyota/Lexus and Honda/Acura vehicles. Please note that these manuals are intended for petrol engine cars (except where diesel is specifically mentioned) built to US specifications.
