About this app
QuickDTC is the free, fast way to look up commercial truck fault codes — and get real answers from a community of drivers and mechanics who have been there.
Stop guessing what a dashboard warning means. Enter the code exactly as it appears on your dash or scan tool, and QuickDTC tells you what it is, how serious it is, whether you can keep driving, and what to check.
WHAT YOU CAN DO
- Look up any SPN/FMI, MID/PID, or dashboard P-code in seconds
- See the meaning, severity, likely causes, symptoms, and basic checks
- Know whether it's safe to keep driving or whether you should stop
- Works across major truck brands — Freightliner, Volvo, Kenworth, Peterbilt, International and more
- Browse the full code database any time
WORKS OFFLINE
Codes are saved to your phone, so you can look them up even with no signal — exactly when you're most likely to need them, out on the road.
A REAL COMMUNITY
QuickDTC isn't just a database. Ask questions, share fixes, and get answers from other drivers and mechanics:
- Post your problem and get real-world advice
- Upvote the answers that actually helped
- See accepted answers marked clearly
- Official QuickDTC Team responses are clearly badged
ALWAYS UP TO DATE
The code database refreshes automatically — when new codes or fixes are added, your app stays current.
QuickDTC is free to use.
