AI is Rewriting the Rules for Diesel Repair
Term

customer journey

The customer journey is the whole process a customer goes through when they bring a vehicle in. If a shop understands each step, it can use tools (including AI) to make the experience smoother.

Term

predictive maintenance solution

Predictive maintenance means using information from the vehicle to guess when something is going to need fixing soon. Instead of waiting for a breakdown, the shop can plan ahead and schedule the work.

Term

just in time

Just in time means ordering or receiving parts right when the job is ready for them. That can help the shop avoid having a big pile of parts sitting around.

Term

service writers

Service writers are the people at the shop who write up the repair paperwork and keep the details organized. If their notes are messy, it can be harder for technicians to know what to do.

Term

technotes

Technotes are the written technical notes used in a repair order to capture observations, diagnostic results, and instructions for the next steps. In diesel repair, clean technotes help technicians and service writers communicate consistently across shifts and roles.

Term

PM services

PM services are planned checkups and routine work meant to prevent problems. Instead of fixing things after they break, you service them on a schedule.

Term

warranty

Warranty is the period where the manufacturer covers certain repairs. After that, owners and fleets have to manage maintenance more independently, so better planning matters more.

Company

PitStop

PitStop is a company mentioned in the episode that builds software for predictive maintenance. The host says it helps solve real problems using data from vehicles and repairs.

Term

TPMS

TPMS is the system that watches your tire pressure and warns you if something’s off. It helps catch tire problems early instead of noticing after the fact.

Term

soot levels

Soot levels are how much dirty particulate builds up in a diesel’s exhaust. If soot is getting too high, it can point to problems and can help you plan service before things get expensive.

Company

FullBay

FullBay is a company mentioned as having a huge amount of data from service orders and repairs. The host’s idea is that more data helps make better predictions about when maintenance should happen.

Concept

break-fix

Break-fix means you wait until something breaks, then you fix it. Predictive maintenance tries to avoid that by planning service ahead of time.

Concept

roadside repairs

Roadside repairs are what you do when a vehicle breaks down and needs help on the side of the road. Predictive maintenance aims to prevent those situations by catching issues earlier.

Term

telematics

Telematics is technology that tracks what a vehicle is doing and sends that information to a computer system. It helps a repair shop or fleet manager spot problems early.

Term

PM scheduling

PM scheduling is planning routine maintenance before something breaks. It’s like following a service calendar, but guided by vehicle data.

Term

predictive data

Predictive data means using past and current vehicle information to guess what will need fixing soon. Instead of waiting for a breakdown, it helps plan service ahead of time.

Term

sensorsthroughoutthevehicle

Sensors are the vehicle’s measuring tools—like things that watch temperatures, pressures, or engine conditions. They send information so problems can be spotted earlier.

Term

red flag

A red flag is an alert that something is wrong enough that you should act quickly. The system is basically saying, “We’ve seen this before—get it checked.”

Term

fleet management system

A fleet management system is a tool for managing many vehicles at once. It helps schedule maintenance and keep vehicles operating efficiently.

Term

parts inventory

Parts inventory just means the spare parts a repair shop keeps in stock. If the shop has the right parts ready, repairs can happen faster instead of waiting on shipping.

Term

parts turns

“Parts turns” is basically how fast a shop goes through the parts it has stored. If parts sit too long, they can become outdated and tie up cash.

Term

KPI

A KPI is a number a business watches to see how well it’s doing. In this case, inventory is important because it affects how quickly repairs can be finished.

Term

obsolete inventory

“Obsolete inventory” is stock that can’t be used or sold because it no longer matches current vehicle needs, part numbers, or demand. For repair shops, it’s a cash-flow problem because the money is stuck in parts that won’t move.

Term

bad data

Bad data is incorrect information in the computer system. If the parts database is wrong, the AI (and people) can end up looking for the wrong parts or wasting time.

Term

catalog

A catalog here means the shop’s organized list of parts. If it’s set up well, it’s easier to find the right part quickly.

Term

parts cross information

Parts cross information is basically “part number matching.” It helps a shop figure out what replacement part corresponds to what’s actually on the truck.

Term

parts availability

Parts availability means whether the needed parts are actually ready to use and can arrive fast. If parts aren’t available, repairs get delayed and that costs money.

Term

AI

AI is computer software that can “look” at an image and make a best guess about what’s wrong. In this case, it’s meant to help find the right parts faster.

Term

fidelity

Fidelity here means how accurate the AI’s information is. Better fidelity means it’s more likely to point you to the right parts based on what it sees.

Jeep Cherokee

A Jeep Cherokee is an SUV made by Jeep. The 1991 version is an older model, and people who own them often do a lot of their own maintenance to keep them going.
