Truck Breakdown Assistant
Tell us what's happening. You'll get possible causes, safe things to look at from the roadside, when to stop driving, and the nearest mobile mechanic.
Safety first
- Get as far off the road as you can, put your hazards on and set out your warning triangles.
- Stay out of traffic. Don't go under the truck on a shoulder.
- Fire, smoke from a wheel, a fuel leak near the exhaust, or anyone hurt: call 911.
1. Your truck (optional)
2. What's happening?
Have a fault code? (SPN and FMI)
Codes are shown on your dash, ELD or scan tool. We link common code numbers to the system they belong to. For the exact definition, use your truck's dash, ELD or the manufacturer's service tool.
