The Truth About Diag, Flat Rate Pay, and Shop Culture with Josh Whiteman
Term

EVAP system

The EVAP system helps keep fuel vapors from polluting the air. It stores these vapors and sends them to the engine to be used as fuel instead of letting them escape into the environment.

Term

case studies

Case studies are examples of car problems that have been studied closely to understand what went wrong and how it was fixed. They help mechanics learn from each other's experiences.

Term

wholesalers

Wholesalers are companies that buy many cars at once, usually to sell them to other car sellers. They focus on selling a lot of cars quickly, even if they don't make much money on each one.

Term

ADAS

ADAS means Advanced Driver Assistance Systems. These are special features in cars that help drivers stay safe, like warning you if you're drifting out of your lane or helping you brake automatically.

Term

Red Seal program

The Red Seal program is a way for skilled workers in Canada to prove they are qualified to do their jobs. It helps them work in different parts of the country without needing to take extra tests.

Term

Ohm's law

Ohm's law is a rule that helps us understand how electricity works. It explains how much electricity flows through a wire based on the voltage and resistance.

Term

pressure transducer

A pressure transducer is a tool that measures how much pressure is in something, like a tire or engine. It sends this information as an electrical signal so that it can be monitored easily.

Term

module

A module in a car is like a small computer that controls different parts of the car. For example, one module might help manage the engine, while another controls the lights.

Term

corrosion

Corrosion is when metal parts get damaged over time because of moisture or chemicals. This can cause problems in how the car works, especially with electrical connections.

Term

diagnostic strategy

A diagnostic strategy is how a mechanic figures out what's wrong with a car. It involves checking different parts and running tests to find the problem.

Term

TSB

A TSB is a notice from a car manufacturer that tells mechanics about common problems with certain models and how to fix them. It's like a guide to help them solve issues more easily.

Term

EVAP light

The EVAP light on your dashboard means there's an issue with the system that keeps fuel vapors from leaking into the air. It's important to fix it to keep your car running cleanly.

Term

code scan

A code scan is when a mechanic checks your car's computer for error messages that can tell them what's wrong with the vehicle. It's like reading a report card for your car's health.

Term

mass airflow sensor

The mass airflow sensor is a part that checks how much air is going into the engine. It helps the car know how much fuel to use for the best performance. If it breaks, the car might not run well.

Term

lean code

A lean code means there's too much air and not enough fuel going into the engine. This can make the car run poorly and cause more pollution. It usually means something needs to be fixed.

Term

fuel trim

Fuel trim is how the car's computer adjusts the amount of fuel going into the engine to make sure it runs well. It helps keep the engine efficient and reduces pollution.

Term

O2 sensor

An O2 sensor checks how much oxygen is in the car's exhaust. This helps the car's computer decide how much fuel to use for the best performance and to reduce pollution.

Term

OBD1

OBD1 is an early car computer system that helps mechanics find problems with the engine and emissions. It gives basic error codes to help diagnose issues.

Term

Mode 6

Mode 6 is a part of the car's diagnostic system that helps mechanics check how well different parts are working. It gives more detailed information than basic error codes.

Term

voltage drop

Voltage drop is when the electrical voltage decreases as it travels through wires. Mechanics check this to find problems in the car's electrical system.

Jeep Wagoneer
Car

Jeep Wagoneer

The Wagoneer is a large SUV made by Jeep. It's designed for families and off-road adventures, with lots of space and modern features.

Term

OBD2

OBD2 is a newer car computer system that helps mechanics check for problems in real-time. It's more advanced than the older OBD1 system and is found in most cars made after 1996.

Term

Power Probe

Power Probe is a tool that mechanics use to check electrical systems in cars. It helps them find problems with wiring and connections quickly.

Term

12-volt battery

A 12-volt battery is the main battery used in cars. It provides power to start the engine and run things like lights and radio.

Term

auxiliary battery

An auxiliary battery is an extra battery in a car that helps provide power for things like lights and electronics, especially when the main battery isn't enough.

Term

service information

Service information is the technical details and instructions that car makers give to help mechanics fix cars. It includes things like wiring diagrams and repair steps.

Term

pinpoint tests

Pinpoint tests are detailed checks that mechanics use to find specific electrical problems in cars. They help narrow down the cause of an issue step by step.

Term

resistance

Resistance is how much a material slows down electric current. In cars, high resistance can mean there are problems with the wires or connections that need fixing.

Term

corroded battery terminals

Corroded battery terminals are when the connections on a car battery get rusty or dirty. This can make it hard for the car to start or cause electrical problems.

Term

Bureau of Automotive Repair

This is a government office that helps people with car repair issues. If someone feels they were treated unfairly by a repair shop, they can report it to this agency for help.

Part

starter motor

This is a part of the car that helps start the engine. If it doesn't work properly, the car might not start at all.

Term

battery terminal cleaning

This is when you clean the parts of the battery where the cables connect. Keeping them clean helps the car start better and keeps the battery working longer.

Term

flat rate tech

A flat rate tech is someone who gets paid a fixed amount for each repair they do, instead of being paid by the hour. This means they can earn more money if they work quickly.

Part

headlight bulb

A headlight bulb is the light that helps you see when driving at night. Sometimes, changing it can be tricky and may require taking off other parts of the car.

Part

taillight bulb

A taillight bulb is the light at the back of a car that shows when the car is stopping or turning. Changing it can sometimes be complicated depending on the car.
