Why On-Site Diagnostics Matter
Towing a truck to a shop just to find out what’s wrong wastes time and money. Our mobile diagnostics let us identify the problem where you are, often starting repairs immediately.

What This Service Covers
Engine diagnostics from Albert’s Road Service goes far beyond reading a fault code and Googling the description. We use factory-level diagnostic software for every major engine platform to perform deep analysis — reading active and inactive fault codes, monitoring live sensor data, running injector balance tests, performing cylinder contribution tests, checking fuel pressure and return flow, and analyzing aftertreatment system operation.
Our diagnostic capability includes software platforms like Cummins INSITE, Detroit Diesel Diagnostic Link (DDDL), PACCAR Davie, Volvo Tech Tool (PTT), and International ServiceMaxx. These aren’t generic code readers — they’re the same tools the dealer uses, and they give us the ability to perform active tests, ECM parameter adjustments, and forced regenerations that generic tools simply cannot do.
We also diagnose aftertreatment-related issues including DPF (Diesel Particulate Filter), DOC (Diesel Oxidation Catalyst), SCR (Selective Catalytic Reduction), DEF (Diesel Exhaust Fluid), and EGR (Exhaust Gas Recirculation) systems. These systems are the single biggest source of check engine lights, derate conditions, and downtime on modern diesel trucks.
Common Problems We Fix
Check engine lights with derate. Your truck goes into a 5 mph or 25 mph forced derate, usually related to aftertreatment faults — high DPF soot load, DEF quality issues, SCR efficiency codes, or NOx sensor failures. We diagnose the root cause and either repair the component or perform a forced regeneration to restore full power.
Hard starting and rough idle. Worn injectors, low fuel pressure, intake air leaks, and faulty sensors cause hard starts and rough running. We use cylinder contribution tests and injector balance testing to identify which injectors are failing and fuel pressure analysis to pinpoint supply problems.
Power loss under load. If your truck runs fine unloaded but loses power pulling a hill, possible causes include turbocharger issues, restricted DPF, intake air leaks, fueling problems, and transmission-related issues. We test boost pressure, EGT (exhaust gas temperature) readings, and fuel delivery to isolate the cause.
Excessive smoke. Black smoke usually means excess fuel or restricted air. White smoke at startup often points to low compression, worn injectors, or coolant leaks into the combustion chamber. Blue smoke means oil consumption. We diagnose the specific cause rather than guessing.
Coolant in the oil or oil in the coolant. This is a serious condition that can indicate head gasket failure, cracked cylinder head, or EGR cooler leak. Early diagnosis prevents catastrophic engine damage. We perform the testing needed to determine the source.
High idle or erratic idle. Throttle position sensor faults, intake air leaks, injector problems, and ECM parameter issues can all cause idle problems. We use live data monitoring to identify the root cause quickly.
Our Process
- Call 561-475-8052. Describe your symptoms — warning lights, performance issues, smoke color, when it happens. This helps us prepare the right diagnostic software and tools.
- On-site diagnostic session. We connect to the engine ECM and read all active and inactive fault codes. But we don’t stop there — we review freeze frame data, monitor live sensor readings, and perform targeted active tests.
- Root cause analysis. Fault codes tell us what the ECM detected, but not always why. We dig deeper using sensor data, mechanical testing, and experience to find the root cause, not just the symptom.
- Clear report. We explain what’s wrong, what caused it, what it’ll cost to fix, and what happens if you don’t fix it. No technical jargon without explanation.
- Immediate repair when possible. Many diagnostic calls lead to on-site repair — sensor replacement, forced regenerations, wiring repairs, filter changes. We carry common parts and can often resolve the issue on the first visit.
Why Choose Mobile Service
Don’t drive a derated truck across town. If your truck is in a forced derate, driving it to a shop means crawling at 5 mph through traffic — or risking further engine damage. Mobile diagnostics comes to you and resolves the issue where you are.
Same tools the dealer uses, without the dealer wait. Dealer service departments are booked weeks out. We use the same factory software and perform the same diagnostic procedures, but we show up today — not two weeks from now.
No diagnostic fishing expeditions. Some shops hook up a generic scanner, read a code, replace the part the code mentions, and hope for the best. When that doesn’t work, they try the next part. That approach is expensive for you. Our factory tools and systematic approach mean we get the right answer the first time.
Florida heat stresses engines harder. South Florida’s year-round heat means cooling systems, turbochargers, and aftertreatment systems are constantly working near their limits. Ambient temperatures above 90 degrees reduce cooling system efficiency and increase exhaust gas temperatures. We account for these Florida-specific factors in our diagnosis.

Frequently Asked Questions
Q: Can you clear my check engine light without fixing the problem? A: We can clear codes, but if the underlying problem isn’t fixed, the light will come back — usually within a few miles. More importantly, ignoring the root cause often leads to forced derate, further component damage, or a roadside breakdown. We recommend proper diagnosis and repair.
Q: What’s the difference between your diagnostics and a generic code reader? A: A generic code reader tells you a fault code number and a generic description. Our factory-level tools show us live sensor data, freeze frame information, active test results, injector balance data, and much more. It’s the difference between being told “your engine has a problem” and knowing exactly which component failed and why.
Q: How long does a diagnostic session take? A: A straightforward fault code diagnosis typically takes 30 to 60 minutes. More complex issues — intermittent faults, derate conditions with multiple codes, or performance complaints without codes — may take 1 to 2 hours. We’ll keep you informed throughout the process.
Q: Can you do a forced DPF regeneration on-site? A: Yes. Forced regeneration is one of our most common diagnostic service calls. Using factory software, we can initiate a stationary regeneration to burn off accumulated soot and clear DPF-related codes. If the regen doesn’t complete, that tells us there’s an underlying issue we need to address.
Q: Do you reprogram ECMs or update engine software? A: Yes, we can perform ECM parameter adjustments and reflashes for most engine platforms. This includes speed limiter adjustments, idle shutdown settings, PTO parameters, and factory software updates that address known issues.
