Description
There are not many things more frustrating than running a scan tool through a vehicles PCM and coming up with DTCs that, at first glance, have absolutely nothing to do with the customer complaints. There is also the infamous “ever since you” complaint, where a different problem springs up after fixing the original complaint.
These totally mind boggling diagnostic puzzles come into the shop every day. The problem with most of these is they cannot be remedied by using traditional diagnostic methods. In this sobering review of diagnostics that lead to more diagnostics, Dave Hobbs teaches you how to think outside the box by covering 4 specific case studies. How to use outside sources and experiences from other technicians to pinpoint the source of a problem you never saw coming.
• The fuel system is running lean but the ABS light is on?
• How can a Multiple Displacement System cause a severe lack of compression?
• Why would the TPMS sensors fault after replacing the key fob module?
• What simple problem will cause the throttle to surge in a rhythmic fashion?
