Diagnostics & Preventive Maintenance
Proactive systems checks, diagnostics, and maintenance programs to reduce downtime and extend engine life.
Book a Diagnostic/PM AppointmentWhen Diagnostics & PM Matter
Modern heavy trucks have complex electronic systems, sensors, and mechanical parts that degrade gradually. Regular diagnostics help catch small issues before they escalate, while a preventive maintenance schedule keeps critical systems in check.
Suggested Intervals & Triggers
- Full diagnostics every 60,000-100,000 km or annually
- Preventive maintenance checks every 25,000-50,000 km (oil, filters, fluids, belts)
- Immediate diagnostics if warning lights, fuel economy drops, or abnormal behavior occur
Key Goals of Diagnostics & PM
- Identify sensor drift, error codes, or electronic faults early
- Monitor systems like engine, transmission, emissions, brakes, electrical
- Extend component life through scheduled maintenance
Common Issues We See
- Fault codes in ECM/TCM from degraded sensors
- Intermittent or hard to replicate electrical faults
- Sensor misreads due to corrosion or poor grounding
- Missed maintenance stressing components (belts, filters)
- Fluid contamination or degradation
Winter Watch - Manitoba Conditions
- Sensors or wiring malfunction from ice or freeze cycles
- Voltage drop interfering with diagnostics or module data
- Salt corrosion on connectors and terminals
- Delayed fault detection as modules enter safe mode
Preventive Tips
- Run full diagnostic scans before and after winter
- Apply dielectric grease on exposed connectors
- Follow tighter maintenance intervals in sub-zero conditions
- Keep diagnostic logs to track system performance over time
