Fuel Trim and Misfire
Ignition System and Cam/Crank Synchronization 2/8/25, Class #220 1:30-4:30 pm Vehicle ignition systems have evolved considerably over the years. With the introduction of variable cam timing, it is more critical than ever for the ECM to keep track of the crank and camshaft positions. To keep pace with diagnosing faults, the traditional “ignition scope” has been replaced with diagnostic codes, misfire counters, scan tool misfire graphing, amp probes, and more. In this class we will illustrate how to accurately diagnose cam-crank correlation faults using a labscope, as well as how to troubleshoot misfires regardless of the vehicle’s ignition system type. After completing this class, technicians will be able to: acquire a cam-crank waveform for analysis, diagnose cam- crank sensor circuit faults, understand the current ignition system types, scope secondary and primary ignition, diagnose primary faults with an amp probe, use misfire counter and other related PIDs effectively, effectively use schematics, and more!

Diagnostics 2/8/25, Class #228 1:30-4:30 pm
This session is designed to help the technician become more proficient in interpreting Fuel Trim PIDs, understanding how they are calculated and what influences them. This information will help provide diagnostic direction for many different engine performance concerns. Misfire complaints are one of the most common experienced today. Within this session we provide a combination of methods using scan tool data to help provide a clear path to pinpointing the root cause. Several vehicle case studies will be reviewed. After completing this session, the student will have the knowledge to: • Apply a logical path of diagnosing Fuel Trim and Misfire concerns on today’s vehicles • Utilize the graphing function of the scan tool to ‘trend’ important scan tool PID (Parameter Identification Data) relationships • Perform Volumetric Efficiency testing to gain diagnostic direction • Diagnose engine Misfire related concerns using the data provided within the scan tool • Recognize Fuel System monitoring strategies,
