DEALER LEVEL DIAGNOSTICS. IN YOUR HANDS.
Read fault codes, reset derates, force DPF regens, and monitor live engine data from the cab or across your entire fleet. Built exclusively for Class 8 heavy-duty trucks.
Stop reacting.
Start controlling.
For years, truck owners and fleet managers have been stuck in the same reactive cycle. A warning light comes on, the truck derates, and suddenly you're losing time, money, and control.
The warning light
A fault code appears. The truck loses power. Your driver is stranded on the side of the road trying to figure out what happens next.
The scramble
Now you’re calling shops, checking tow options, and guessing whether the truck can safely keep moving or needs immediate attention.
The downtime
Every hour the truck sits still costs money. Missed loads, delayed deliveries, and expensive diagnostics start piling up fast.
You take control
Get dealer-level diagnostics, live fault data, remote commands, and real-time visibility so you can make decisions before small problems become major downtime.

Saved me from a $1,200 shop visit. Forced a regen from my phone in 20 minutes and got back on the road. Pays for itself in one use.Owner-operator, Cummins ISX
We run 23 trucks. Before OTR Remote, a derate meant pulling the truck. Now I reset it from my desk and keep the load moving.Fleet manager, Midwest Freight
I knew about a DPF issue on truck 14 before my driver even noticed. That's the difference. You're ahead of the problem instead of behind it.Operations director, 48-truck fleet
