Mobile Diesel Diagnostics
Find the fault before throwing parts at it.
Advance responds to commercial breakdowns with diagnostic capability aimed at identifying the actual cause, determining whether a roadside repair is practical, and getting the right repair path started.
Mobile fault tracing for commercial trucks
A code identifies the system that noticed a problem; it does not always identify the failed part. Roadside diagnostics can evaluate engine and aftertreatment faults, electrical and charging problems, no-start conditions, sensor and circuit issues, air-system faults and derates.
- Active and inactive fault-code review
- Battery, charging, starter and power-distribution testing
- DPF, DEF and SCR fault diagnosis
- Sensor, connector and wiring checks
- Air-system and brake-related fault tracing
Diagnosis should lead to a practical next step
If the failure is repairable roadside, the technician can proceed when parts, conditions and safety allow. A forced regeneration is used only when the underlying conditions support it. If the truck needs shop-level work, towing is available through the same dispatch number.
Call with the symptoms, warning messages and fault codes you can safely provide. You do not need to know the failed component before requesting service.
