How to Solve difficult DTCs
Presented by SMP, Duration approx. 3 hours
This course will explore why codes cause grief and how to successfully repair them. After almost 25 years of OBD2, technicians have learned to cope with most of the problems that come their way. But there are some systems that continue to be difficult to diagnose. Many of these are old and while many are fairly new. Some types of codes that can be difficult to diagnose include evaporative system, random misfire, Variable Valve Timing, catalyst efficiency, electronic throttle control, and fuel trim. During this course, technicians will be able to:
o Identify EVAP faults
o Perform random misfire diagnosis
o Catalyst efficiency code diagnosis
o Analyze scan tool data for fuel trim diagnosis
o Describe VVT operation
