What to Expect

Your Smog Check, Step by Step

Here's exactly what happens when you come to our Higuera St shop β€” from prep to pulling away.

Before You Arrive

Quick Prep

What to Bring

Your vehicle and payment. DMV renewal notice speeds check-in but isn't required.

Check Engine Light

If it's on, automatic fail. Get it diagnosed first β€” we handle diagnostics here too.

Warm It Up

Drive for a few minutes before arriving. Coming from anywhere in SLO, Cal Poly, or the coast? That drive is plenty.

Walk-In or Book?

Either works. Book online for guaranteed timing. Walk-ins are welcome β€” weekday mornings are quietest.

At the Shop

The Inspection Process

1

Check In

Pull into our lot on Higuera at Madonna. Service advisor takes your vehicle info. Booked online? Already queued.

2

Visual Inspection

Quick walk-around β€” catalytic converter, gas cap, exhaust, hoses. Confirming everything's present and connected.

3

OBD-II Diagnostic Scan

For 1996+ vehicles, technician plugs into the diagnostic port under your dash. Reads trouble codes, checks monitor readiness, verifies check engine light function.

4

Results & Filing

10–15 minutes for the test. Pass and we file your certificate electronically with the DMV same day.

5

Done

Pay, grab your receipt, head out. Total visit under 25 minutes. Enough time before your Thursday night Farmer's Market stroll.

If Your Vehicle Doesn't Pass

We Fix It Here

Most vehicles pass. If yours doesn't, your technician explains what failed β€” clearly, without jargon.

As a full Multicare facility, we diagnose and repair most emissions issues right here on Higuera. Common causes: oxygen sensors, catalytic converters, gas cap seals, incomplete readiness monitors. Many are same-day fixes.

Re-test after our repair at no additional inspection fee. One shop, one visit.

Pro Tips

Set Yourself Up to Pass

Fix the Check Engine Light

Automatic fail if on. Get diagnosed before your smog appointment.

Drive It First

Cars that sit (common for Cal Poly students who mostly bike) may have incomplete monitors. Drive normally for a few days before testing.

Come Early

Don't wait until registration deadline day. Come a few weeks early β€” if something needs fixing, you'll have time.

15 Minutes on Higuera. Done.
