FIND THE ROOT CAUSE
Advanced diagnostics. Less guesswork.
Scan-tool data, electrical testing and mechanical verification, done at your location. We find the real cause before anything gets replaced.

HOW WE DIAGNOSE
Test, don’t guess.
- Step 1
We listen first
When it happens, how often, what changed and what’s been done already. The story narrows it down fast.
- Step 2
Full scan & live data
Every module, stored and pending codes, freeze-frame and live data from a professional Autel scan tool.
- Step 3
Pinpoint tests
Voltage drops, wiring, fuel pressure, boost and smoke tests, injector balance rates and mechanical checks to prove the cause.
- Step 4
Clear estimate
You get the cause, what it takes to fix and an itemized estimate before any repair.
- Step 5
Verify the fix
After the repair we re-scan, clear codes and road-test or run the truck to confirm it’s fixed.
FROM OUR SHOP
Dealer-level tools, at your truck.
WHAT WE DIAGNOSE
Every system on your truck.
Engine & drivability
Low power, hard starts, misfires, rough idle, smoke and stalling.
Electrical systems
Wiring, batteries, charging, sensors, modules and intermittent faults.
Network & modules
CAN-bus communication faults, no-communication modules and programming concerns.
Turbo & air systems
Boost control, VGT performance, charge-air leaks and intake restrictions.
Fuel injection
High-pressure fuel, injector balance rates, return-flow tests and supply-side testing.
Fuel systems →Emissions & DPF/DEF
Regen problems, NOx sensors, DEF quality and derate codes.
Transmission
Shift concerns, transmission codes, adaptive values and fluid condition.
Overheating
Cooling-system pressure tests, fan clutch, thermostat and head-gasket checks.

DASH WARNING LIGHTS
What’s that light mean?
A quick guide to the warnings we get called about most.
Check engine light
A stored fault in the engine or emissions system. Steady: book soon. Flashing: stop and call.
DEF / emissions warning
Usually a countdown to a speed or power derate. Don’t ignore it; book quickly.
Wait-to-start / glow plug
Glow plug, relay or controller fault. Expect hard starts in cold mornings.
Coolant temperature
Pull over safely and shut it down. Driving hot can warp heads and blow gaskets.
Battery / charging
Alternator, batteries or wiring. Diesels need strong batteries to crank.
ABS / traction
Wheel-speed sensors, wiring or the ABS module. Normal brakes still work, but have it checked.
Why not just read the code?
A code is a symptom, not a diagnosis.
P0087 (low rail pressure) can be a clogged filter, a failing lift pump, a leaking injector or a dying high-pressure pump. Parts-cannon repairs get expensive fast. We test until we know, then fix it once.

Warranty details →OWNER QUESTIONS
Before you book.
How much does a diagnosis cost?
Diagnostic time is billed at your truck class rate: $149/hr (Class 1), $198/hr (Class 2–6) or $298/hr (Class 7–8). We tell you up front what testing we plan to do.
Can you diagnose at my location?
Yes. Our scan tools and test equipment come to your home, job site or yard.
My parts store read the code for free. Why pay for diagnosis?
A free code read tells you which system is unhappy, not which part failed. Testing confirms the cause so you don’t pay for parts you didn’t need.
Do you diagnose gas trucks too?
Yes. Ford, Ram, Chevrolet and GMC gas trucks get the same process.
