A GPS that reads the vehicle's computer can report its fault codes, such as P0300. OBD Doctor gathers them for the whole fleet, explains each one in plain words and puts what needs checking today at the top.
Every fault has its urgency: check today, check this week or watch. The fleet manager knows where to start.
P0087 stops being a number: "fuel rail/system pressure too low", what it means and what to check at the workshop.
When each fault appeared, when it cleared and how many days it stayed active, on a timeline.
By code, by make and model and by group, and whether the fleet is getting better or worse week by week.
Each fault goes from detected to in the workshop to repaired. If the company uses FleetCare, the work order is created from the vehicle page.
