Battery Issues
Related Problems: Parasitic draws (something draining the battery when the car is off).
Diagnosis: Testing battery health, charge level, and ability to hold a charge.
Charging System Problems
Diagnosis: Checking alternator output voltage and current, inspecting the drive belt.
Starting System Problems
Diagnosis: Checking for power to the starter, listening for unusual noises (clicking, whirring), testing the starter motor itself.
Wiring and Connections
Related Problems: Short circuits, open circuits, intermittent electrical issues.
Ignition System
Diagnosis: Identifying issues causing a no-start condition, rough running, or misfires (spark plugs, ignition coils, ignition module, crankshaft/camshaft position sensors).
Computer Systems and Sensors
Diagnosis: Using scan tools to read diagnostic trouble codes (DTCs) and diagnose problems with the engine control unit (ECU), transmission control unit (TCU), and various sensors (oxygen sensors, mass airflow sensor, etc.).
Dashboard and Instrument Cluster
Diagnosis: Identifying issues with gauges not working, warning lights staying on, or the entire instrument cluster malfunctioning (wiring, sensors, the cluster itself).
