Freightliner work

What we fix on Freightliner units.

Highway Cascadias fail differently from urban units. We start from the duty cycle, then the codes.

DD13 / DD15 diagnosticsDDDL fault trees, injector and turbo actuator testing, live data capture on the road.
Aftertreatment and DEF faultsDEF quality and dosing, SCR efficiency codes, NOx sensor verification.
DPF service and regen faultsSoot and ash loading assessed, forced regens run, filters cleaned or replaced.
Air brake and ABS workChambers, slack adjusters, valves and ABS faults, plus pre-CVSA blitz checks.
Detroit DT12 and drivetrainAutomated transmission faults, clutch actuator calibration, differentials and driveshafts.
Annual safety inspectionFull MTO annual with the itemized defect list and the sticker on a clean pass.
How it runs

Diagnose first, quote second, repair third.

01

Fault pull

Full ECM and aftertreatment scan, freeze-frame data captured before anything is cleared.

02

Trace it

Sensors, wiring and actuators verified against spec — no parts ordered on a guess.

03

Written quote

Parts and hours itemized, with the must-do work separated from what can wait.

04

Repair and verify

Work completed, then re-scanned and road-tested before the unit leaves.

Book it

Book your Freightliner in.

Send the code and the mileage. Aftertreatment faults are the fastest way to lose a Cascadia to a derate, so those get slotted first.

Do you have Detroit software?+

Yes — DDDL for Detroit engines, plus Cummins INSITE, Cat ET and JPRO for everything else in a mixed fleet.

Can you fix a DEF quality fault without replacing the tank?+

Usually. We test the fluid, the quality sensor and the dosing unit before condemning any of them.

What about an M2 with a Cummins?+

No problem — mixed drivetrains are routine here. INSITE covers the Cummins side.
