DVIR is no longer a clipboard. iMatrix combines the driver's pre-trip walk-around with live CAN diagnostics from FC-501, Sentry-1 cargo verification, and NEO-1 reefer pre-cool readings — into one signed, timestamped record that auditors and drivers both trust.
iMatrix mobile app guides the pre-trip and post-trip walk-around. Photos, defects, and notes attach to the trip record automatically.
FC-501 reads brake pressure, lamp circuits, fault codes, and tire-pressure SPNs in real time — so a "no defects" check has the bus to back it up.
One PDF per inspection. Driver signature, vehicle ID, GPS at submission, photos, CAN snapshot, sensor readings — everything FMCSA wants on a single page.
A driver's eyeballs catch some things; the CAN bus and ambient sensors catch the rest. Put together, FC-501, Sentry-1, and NEO-1 turn a 5-minute walk-around into a full vehicle health snapshot.
Live J1939 fault codes, brake-system pressure, lamp-circuit status, and odometer at the moment of inspection. Auto-fills the DVIR's mechanical section so the driver isn't guessing.
Door-open events between post-trip and next pre-trip flag potential tampering or unauthorized loads. The driver sees "last opened: 18:42 yesterday" before signing.
For refrigerated DVIR, NEO-1 confirms cargo box is at setpoint before the driver signs the pre-trip. No more "the reefer was running" with no proof.
Drivers don't change their workflow — they just open the iMatrix app at start of shift. Everything else happens in the background and ends up in the same record.
Driver opens the app. iMatrix Cloud pulls the most recent FC-501 health snapshot and the overnight Sentry-1 / NEO-1 events into the inspection form.
Driver checks each item, captures photos, notes defects. The app prompts on items the bus already flagged ("DTC P0420 — confirm exhaust").
Driver signs digitally. iMatrix Cloud timestamps with GPS, attaches the CAN snapshot, and emits the PDF to the maintenance queue and FMCSA archive.
If a DOT inspector pulls the truck over, the most recent DVIR is one tap away in the driver app — and one query away in iMatrix Cloud for the back office.
FMCSA-mandated DVIR with CAN-confirmed brake, light, and engine status. Defect-to-shop hand-off is automatic.
NEO-1 confirms reefer is at temp before the driver signs. FSMA documentation builds itself.
Lighter inspection workflows, same audit trail. Photos of vehicle damage protect the driver and the company on rental returns.
