↗Mobile & in-shop diagnostics · Quebec
Stop replacing.
Start proving.
Electrical, electronic and mechanical diagnostics for trucks, heavy equipment, commercial vehicles and unfamiliar machinery. The system dictates the test—not a parts list.
◆ Machine measurements◆ Ranked hypotheses◆ Confirmed cause
The difference
A code, noise or loss of power is a clue. Diagnostics connect that clue to the physical mechanism that produced it.
Diagnostic capabilities
One fault can cross several systems.
A “mechanical” fault may be electrically controlled. An “electrical” fault may be caused by mechanical load. We follow energy and information across the machine.
Mechanical
Engines, transmissions, cooling systems, vibration, noise and performance loss.
↗Diesel & engine controls
Injection, boost, aftertreatment, live data and functional testing.
↗Hydraulics & equipment
Pressure, flow, temperature, controls and subsystem interactions.
↗Diagnostic reasoning
From symptom to demonstrated cause.
Live evidence from the machine comes first. Hypotheses remain provisional until a measurement supports or eliminates them.
Define the symptom
Reproduce the fault and separate observations from assumptions.
Understand the system
Map inputs, outputs, enable conditions and energy paths.
Test with purpose
Choose the measurement that eliminates the most hypotheses.
Prove the cause
Confirm the failure mechanism and verify operation after the repair.

Fault causing downtime now?
Bring the diagnostic process to the breakdown.
Our dedicated 24/7 roadside unit handles no-starts and complex field failures.
Fleet-level diagnostics
What if your PEP included a diagnostician?
Turn preventive inspections into evidence about recurring faults and avoidable downtime.
The next logical test
Describe the symptom. We will start with the facts.
Include the machine, location, fault conditions and testing already performed.
