How to find a good auto repair shop

What happens here

After connecting the scanner, the device powers on and automatically begins to communicate with the vehicle's various control modules, including the Engine Control Unit (ECU) and the Transmission Control Module (TCM). The scanner retrieves any stored Diagnostic Trouble Codes (DTCs), which are standardized codes indicating specific malfunctions. While the video explicitly shows an engine code (P2646 - Rocker Arm Actuator System Performance), the process would be identical for retrieving transmission-related codes (e.g., P07XX series codes).

Goal: Retrieve stored error codes from the vehicle's computer
