Warning light diagnostics. Real answers.
Check engine light that won't clear. Lane assist or collision alert that came on after a repair. Intermittent stalling, limp mode, or a calibration that won't complete. We scan the full system and find the actual cause — not a guess.
Tell us what your car's doing. We'll tell you what's actually wrong.
Diagnostics for your specific car.
Each manufacturer has its own scan tool, its own warning codes, and its own pattern of common findings. Pick yours for the brand-specific diagnostic process — including what we look for before any calibration is even possible.
Domestic — Ford, GM, Stellantis.
Scan and diagnostic procedures for F-Series, Silverado, Ram, Wrangler, and the rest of the domestic lineup.
Your Buick is the quietest car in your driveway, which is exactly why you noticed something was off in the first place.
View diagnosticsCadillac
Your Cadillac told you Super Cruise is unavailable, your Lyriq is showing a charging fault, or your Escalade is throwing warnings after a small tap in the parking lot.
View diagnosticsChevrolet
Silverado runs Springfield's job sites.
View diagnosticsChrysler
Your Chrysler Pacifica is throwing a Driver Drowsiness Detection warning, your Pacifica Hybrid stopped charging overnight, or your Voyager is showing a service light you have never seen before.
View diagnosticsDodge
Your Dodge is throwing a warning light, acting strange after a repair, or just feels off.

F-150 is the unofficial state vehicle of Illinois, and a lot of them carry plow mounts, fifth-wheel hitches, lift kits, and toolboxes the factory never imagined.
View diagnosticsGMC
Your GMC is the workhorse on your property and the long-haul driver on your trips.

Your Wrangler is throwing weird codes after a 4-inch lift and 35s.

View diagnosticsJapanese — Toyota, Honda, Nissan, Subaru, Mazda.
Brand-correct diagnostics for Toyota, Honda Sensing, Nissan ProPILOT, Subaru EyeSight, Mazda i-Activsense, plus the AcuraWatch and Infiniti luxury tiers.
Your Acura is built around Precision Crafted Performance.
View diagnosticsHonda
Honda owners keep their cars longer than almost anybody else on the road, and that means our diagnostic bay sees Honda Sensing in every stage of its life — from the first 2015 systems that just barely qualified as ADAS to the brand-new Honda Sensing 360 suite.
View diagnosticsInfiniti
Infiniti's dealer network has been shrinking for years, and if you own a Q50, Q60, QX50, QX60, or QX80 in central Illinois, the nearest factory store is no longer a quick drive.
View diagnosticsMazda
Mazdas are engineered as a tightly tuned system — the steering, the engine, the brakes, and the cameras are all talking to each other every second you're driving.
View diagnosticsNissan
Nissan put driver assistance technology in nearly every model on the road.
View diagnosticsSubaru
Your Outback flashed a check engine light on the way home from Costco.
View diagnosticsToyota
Toyota builds some of the most reliable cars on the road, and Springfield is full of them — RAV4s in every driveway, Tacomas and Tundras at every job site, Camrys and Corollas in every parking lot.
View diagnosticsKorean — Hyundai, Kia, Genesis.
Hyundai SmartSense, Kia Drive Wise, and Genesis Active Safety diagnostics — including HDA 2 lane-change health checks.
European — BMW, Mercedes-Benz, Audi.
Dealer-level scans for BMW Driving Assistant tiers, Mercedes Distronic and Drive Pilot, and Audi pre sense — without the drive to Champaign or St. Louis.
When a yellow or red icon shows up on the virtual cockpit and you don't recognize it, you need someone who can talk to every control unit your Audi has on board.
View diagnosticsBMW
BMW packs more electronics into a 3 Series than most full-size trucks, and when something goes wrong it usually surfaces in two places at once — the iDrive center screen and the cluster.
View diagnosticsMercedes-Benz
The nearest Mercedes-Benz dealer to Springfield is in Bloomington, Champaign, or St.
