A dash light only tells you that something is off. Mobile diagnostics tells you what, and Dash Power Workz does it where the truck is parked: at the yard, at the dock or on the shoulder. You don’t pay for a tow just to find out what’s wrong.
Codes are a starting point, not the answer. A sensor code can come from the sensor, the wiring to it, a connector full of water or the system that sensor is watching. We trace it back before replacing parts.
What we diagnose
- Check engine, stop engine and derate warnings
- Engine fault codes, active and inactive
- Electrical and electronics: wiring, connectors and grounds
- Charging and starting: batteries, alternators and starters
- Pressure, temperature, speed and NOx sensors
- Aftertreatment faults: DPF, DEF and regen problems
- Air system and brake warning lights
- Trailer lighting circuits and plugs

Electrical problems take patience
A chafed wire under the frame, a corroded plug at the nose box or a bad ground can show up as three different problems at once. Electrical and electronics work is a regular part of our week, on tractors and trailers both.
Once the cause is found, you get a plain answer: what failed, what it takes to fix, and whether the truck is safe to move in the meantime.
