HEAVY-DUTY DIESEL DIAGNOSTICS
Find the Cause
DIAGNOSE THE PROBLEM BEFORE REPLACING PARTS
SYSTEMATIC TROUBLESHOOTING FOR COMMERCIAL TRUCKS, SEMIS AND CHARTER BUSES
Warning lights, power loss, starting trouble, abnormal smoke and other performance concerns can have several possible causes. Bo’s Garage evaluates the symptoms and checks the related systems to help identify where the problem begins.
Our diagnostic approach combines the available electronic information with visual inspection, measurements and system testing appropriate to the concern. The findings are then used to recommend the next repair step.
We diagnose CAT, Cummins, Detroit Diesel, Mack, International, Volvo and Paccar diesel engines. Call with your vehicle information, warning lights and symptoms so we can discuss the problem.

Why Diagnostics Matter
THE SAME SYMPTOM CAN HAVE MORE THAN ONE CAUSE
GOOD REPAIR DECISIONS BEGIN WITH ACCURATE INFORMATION
Modern heavy-duty diesel engines rely on mechanical, electrical, fuel, air and cooling systems working together. A problem in one system can create symptoms that appear to come from somewhere else.
Fault codes can provide useful direction, but they do not always identify the failed component by themselves. Proper diagnosis may also require visual inspection, measurements and testing of the systems related to the complaint.
Identifying the source of the problem helps define the appropriate repair and reduces unnecessary parts replacement.
WHEN DIAGNOSTIC SERVICE MAY BE NEEDED
The symptoms and operating conditions help determine which systems should be inspected and tested.
Our Process
FROM SYMPTOMS TO A REPAIR PLAN
A SYSTEMATIC APPROACH TO FINDING THE SOURCE OF THE PROBLEM
GATHER INFORMATION
We review the truck, bus or engine information, warning lights, symptoms and the conditions under which the problem occurs.
INSPECT & REVIEW DATA
The vehicle receives an initial inspection, and available electronic fault information is reviewed when applicable.
TEST RELATED SYSTEMS
The mechanical, electrical, fuel, air or cooling systems connected to the concern are checked as needed.
EXPLAIN THE FINDINGS
We review what was identified and discuss the recommended repair or next diagnostic step.
From Symptoms to a Plan
CLEARER ANSWERS FOR HEAVY-DUTY REPAIRS
DIAGNOSTICS HELP DEFINE THE RIGHT SCOPE OF WORK
Diagnostic findings may point to a sensor or wiring concern, fuel or air-delivery problem, cooling-system issue, worn component or internal engine damage.
Because Bo’s Garage also provides full-service heavy-duty repair and diesel engine rebuilding, the next stage of work can be handled by the same shop when the required service is available.
Call with the year, make and model, engine manufacturer, warning lights and symptoms you are experiencing.
