CoreDiag analyzes every repair order with NHTSA recalls, complaints, TSBs, and AI — giving your techs ranked diagnostic suggestions in seconds. No extra tools to learn.
14-day free trial. No credit card required.
Intermittent rough idle on a 5.0L F-150 with a cycling MIL is consistent with a VCT system fault or carbon buildup on intake valves. Recommend pulling freeze frame data and checking for P0011/P0021 before disassembly.
How it works
A service writer enters the vehicle and customer concern into CoreDiag. VIN decode pulls the rest automatically.
CoreDiag cross-references NHTSA recalls, complaints, and TSBs for that vehicle, then generates ranked diagnostic suggestions in seconds.
The tech reviews the AI suggestion on the RO, runs the recommended tests, and rates the accuracy — making CoreDiag smarter over time.
