Batteries, alternators, starters, TIPM and module faults, grounds, and wiring on 1500-5500 trucks tested where the unit is parked.

Why Call a Mobile Ram Tech
Keep your Ram trucks working, not waiting
Whether it is one 1500 or a yard full of 3500 and 5500 work trucks, dropping a Ram at a dealer means days in a queue and a loaner you probably will not get. For most driveability, electrical, brake, and maintenance work, that trip is avoidable.
Lowcountry Diagnostics brings the diagnostics and tools to your Ram and works the fault in order, then either fixes it on-site or gives you a clear direction. For fleets, we schedule the whole run at your yard so trucks are back in service the same day.
Why operators call us
- Mobile service where the truck is sitting
- Testing before parts replacement

How We Work
What happens on a Ram truck call
1. Tell us the truck
Year, Ram 1500 through 5500, gas or diesel, warning lights, and the symptom point us to the right first tests.
2. We come to you
Yard, jobsite, home, or roadside across the Charleston area — no tow needed to start diagnosing.
3. Diagnose before parts
Codes, live data, and targeted circuit testing confirm the actual fault instead of guessing.
4. Repair on-site where practical
Electrical, brakes, cooling, and maintenance are handled at the truck; bigger jobs get a clear direction.
5. Plain-language findings
You learn what was checked, what failed, the likely cause, and the recommended next step in writing.
6. Keep the fleet moving
Fleet Rams get priority scheduling and preventive maintenance to head off the next breakdown.
