LONG-HAUL TRACTOR
Iveco Stralis / S-Way
Iveco Cursor 11 / 13 engines with Hi-SCR are efficient when sensors and harnesses are healthy. Wiring and gearbox oil pressure are the recurring themes.
SYMPTOMS
What you'll notice
Tell-tale signs the Iveco Stralis / S-Way is asking for attention.
- Intermittent misfire cleared by wiggle-test
- AdBlue / NOx fault with no obvious cause
- Harsh shifts or transmission warning
- Engine derate after long highway runs
DIAGNOSTICS
How we find the fault
- 1
EASY IVECO multi-ECU scan
Capture EDC17, UCM and TCU faults with freeze-frame.
- 2
Harness continuity & resistance
Pin-to-pin test on injector and SCR harness against OEM spec.
- 3
NOx / urea sensor verification
Cross-check sensor outputs vs commanded dosing.
- 4
Transmission live data
Monitor line pressures, solenoid duty cycles under road test.
