To illustrate the practical benefits of diagnostic scanning, here are some case studies of real-world applications.

9.1 How Diagnostic Scanning Solved a Complex Engine Problem

A customer brought their car into a repair shop complaining of poor engine performance and frequent stalling. The technician performed a diagnostic scan and found a DTC indicating a problem with the mass airflow (MAF) sensor. Further testing revealed that the MAF sensor was indeed faulty, causing the engine to receive incorrect air-fuel mixture information. Replacing the MAF sensor resolved the issue and restored the engine’s performance.

9.2 Using Bidirectional Control to Diagnose an ABS Issue

A technician was diagnosing an ABS (Anti-lock Braking System) issue on a vehicle. The ABS warning light was illuminated, and the customer reported that the ABS system was not functioning properly. The technician used a diagnostic tool with bidirectional control to activate each ABS solenoid valve individually. This revealed that one of the solenoid valves was stuck, preventing the ABS system from functioning correctly. Replacing the faulty solenoid valve resolved the issue.

9.3 Data Logging to Identify an Intermittent Transmission Problem

A customer complained of intermittent transmission slipping on their vehicle. The technician performed a diagnostic scan but found no DTCs. However, the technician suspected a problem with the transmission control system. They used a diagnostic tool to log data from the transmission control module (TCM) while driving the vehicle. Analysis of the data log revealed that the TCM was intermittently losing communication with the engine control module (ECM), causing the transmission to slip. Repairing the communication wiring resolved the issue.
