These are real pages from the book. The table of contents is the full one: 8 parts and 60 topics.

The Problem Isn't You. It's How It Was Explained to You.

You're under a 2006 pickup with a flashlight. The catalytic converter isn't the original, and you have to decide right there: does it pass the visual or not?

The manual has the answer, but it's spread across paragraphs on replacement parts, Executive Orders and model years. You read it last night, and under the truck it's gone.

Aftermarket converters need a CARB EO number covering that model year

In the book, that converter is one page: the right install drawn next to the wrong one, with an arrow pointing to the label. Aftermarket converter? Look for a CARB EO number that covers that model year.

The PCV system, EVAP, EGR, the MIL bulb check and the readiness monitors work the same way: each one has its own page, drawn.

You get it, you check it and you move on, without going back to the manual between cars.

COMPARE FOR YOURSELF

The Same Topic, Two Ways to Study It

THIS
  • The manual: line after line of rules
  • EVAP components explained only in words
  • You reread it three times to find what makes it fail
Evaporative emission control systems shall be inspected for the presence and proper connection of all components originally installed by the manufacturer, or approved replacements thereof, including but not limited to the charcoal canister, purge control valve or solenoid, associated vapor and vacuum hoses, and the fuel tank filler cap. Any component found missing, disconnected, modified or defective, as determined by reference to the vehicle emission control information label and applicable manufacturer specifications, shall result in failure of the visual inspection.
FOR THIS
  • The EVAP system in one drawing
  • Missing, disconnected or modified: visual fail, in one box
  • The VECI label tells you which parts should be there
Visual inspection: is it there, is it connected, is it the right part

One Page, One Topic, All Clear

Think of it this way:

A 2003 sedan rolls into the bay. You plug into the DLC: EVAP shows incomplete, every other monitor complete. Pass or fail? You need the answer before the customer asks.

In the book you open the monitors page: complete, incomplete and not supported side by side, with the model-year rule right under them. Gas cars 2000 and newer: EVAP is the only monitor that may be incomplete. On readiness, this one moves on.

1976–1999 gasoline: tailpipe test. ASM in enhanced areas, TSI outside them.

Same with the VECI label, the fuel cap test, two-speed idle and the five gases with their units: each one on its own page.

Smog Check Inspector Illustrated is 8 parts and 60 topics, all drawn, and it ends with the whole inspection on one page plus a quick review of monitors, codes and gas readings.

What you see drawn, you don't have to memorize.

Frequently Asked Questions

Is it for me if I've been fixing cars for years and now want the inspector license?

Yes. It doesn't teach you how a car works: it puts the California inspection procedure, the program terms and the rules in order, one topic per page.

Where does the content come from?

From the Bureau of Automotive Repair materials: the Smog Check Manual, the Smog Check Inspection Procedures Manual and the regulations in CCR Title 16. It follows today's OBD-based inspection with BAR-OIS: most 2000-and-newer cars get the OBD test, and the tailpipe test (ASM or two-speed idle) is covered for the older vehicles that still get it.

Is it official material?

No. It's an independent illustrated study book, not affiliated with BAR, CARB, the DMV or PSI.

Does it replace the required training courses?

No. It doesn't replace the BAR-required training or hands-on practice, it doesn't count as training hours and it doesn't come with a certificate. It's for studying and reviewing what you learn there.

Are the practice questions the ones on the exam?

No. They're written for this book, in exam style, and each answer points you to the page to go back to.

When and how does it arrive?

The book and the 2 bonus books arrive as PDFs by email, at the address you enter at checkout. One-time payment, no subscription.

Does it work outside California?

No. It's built on California's Smog Check program: BAR rules, California limits and the PSI inspector exam. Other states run different emissions programs with their own rules.

Can I have it on paper?

We don't ship printed copies, but the PDF is printable: print it at home or at a print shop and keep it in the bay.

How does the refund work?

You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.

Before You Close This Page

No more rereading the manual with nothing sticking.

The CARB EO rule, the monitors and the five gases: you see them drawn, and that's it.

You walk into the PSI exam knowing where everything is.

Drawings make studying faster.
