Auto Repair Intermediate

A scanner reads codes. A diagnostician reads stories. This lesson covers the freeze-frame data, mode 6 stats, and live-data approach that turns a P0171 into a 15-minute fix instead of a parts-cannon afternoon.

Tires don't wear unevenly by accident. This lesson covers ball joint and tie rod inspection, alignment angles (camber, caster, toe) and reading tire-wear patterns like a forensic report.

Brakes are the #1 safety system. This lesson moves past pads and rotors into hydraulic diagnosis, ABS module faults, and the seized-caliper symptoms that send untrained techs in circles.

The best techs lose money to bad write-ups. This lesson covers labor times, parts markup, the multi-point inspection that sells real work honestly, and the workflow that doubles a shop's throughput.
