TorqueTelltale / J1939 and selected gasoline OBD-II code lookups with evidence-first diagnostic reports for a better shop handoff.
Know what failed.
Know what to bring.
TorqueTelltale gives gasoline car and light-duty truck drivers a generic OBD-II code reference with safe evidence prompts, while keeping the existing J1939 and light-duty diesel DPF references available for their current lanes.
Working on a light-duty diesel truck? Open the DPF code reference.
A warning light is a clue. The repair needs a case file.
The useful answer is rarely just a part number. TorqueTelltale connects what the truck reported with what the driver saw, measured, and tested in the field.
Context over code
Blend ECU data with the unit, symptoms, conditions, and the story behind the alert.
Proof over guesswork
Turn photos, measurements, and guided electrical checks into evidence a shop can act on.
A handoff that travels
Give the next technician the signal, the confidence, the exclusions, and the next best move.
The field workflow
From dashboard alert to mechanic proof.
Built for the minutes between a fault and a repair decision—when clarity saves the most time.
Read the whole signal
Look up selected generic gasoline OBD-II codes or heavy-duty J1939 signals, then put the code in vehicle context.
Test before you buy
Capture symptoms and safe, code-relevant observations to give the receiving shop useful evidence.
Hand off with confidence
Send the receiving shop a Mechanic Proof report with findings, exclusions, likely parts, and next tools.
The handoff
Give the shop more than a code.
A Mechanic Proof report makes the reasoning visible. That means fewer blind parts swaps, fewer circular calls, and a better first conversation at the bay.
