Heavy Duty & Commercial Vehicle Diagnostic Tools

When a commercial vehicle is down, the meter is running. Fleet downtime costs between $500 and $2,000 or more per vehicle per day in lost revenue, missed deliveries, contract penalties, and emergency rental costs. The difference between diagnosing a fault in 30 minutes versus 3 hours is not just a matter of shop efficiency — it is the difference between a fleet customer who stays with you and one who finds a shop with better tools. Heavy-duty and commercial vehicle diagnostics require tools that speak the protocols these vehicles use, cover the wide range of engine, transmission, ABS, and body control modules found in Class 4 through Class 8 trucks, and provide the depth of diagnostic data that fleet managers and commercial repair shops demand.

Commercial vehicles are a different world from passenger cars. They use different communication protocols — J1939, J1708/J1587 in addition to standard OBD-II — and come from a wider variety of manufacturers with less standardization across brands. A tool that is excellent on passenger cars may be completely blind on a Freightliner, a Peterbilt, or an International. Autel's commercial vehicle solutions are built specifically for this segment.

In commercial repair, diagnostic speed directly translates to revenue. A tool that helps your technician find the fault in 30 minutes instead of 2 hours saves 90 minutes of bay time, reduces vehicle downtime for the customer, and allows your shop to turn more jobs per day. The MS909CV's diagnostic depth and guided procedures are designed to reduce diagnostic time on every job.
