Used Vehicle Inspection: Why, How and a better way

Vehicle Inspections are especially important for “high value” used – Cars, Motorcycles, Commercial Trucks & RV’s. A used vehicle that has suffered damage through poor driving, hard use or been subject to an accident – is not as valuable as a vehicle that has been lightly used, well maintained and never been subject to any accidents.

Used car buyers are often warned to obtain a complete inspection before purchase to minimize the risk that the used vehicle has hidden defects or damages.

Likewise, for those dealing with a large used item inventory, such as motor vehicle leasing companies or fleet operators, need reliable vehicle inspections. For example, cars coming off short-term or long-term leases need to be inspected so the leasing agent can know whether to charge the lessee for damage the lessee is responsible for.

In the past, inspections were generally performed manually using pre-printed forms. The more modern is a web upload version to upload the status  memory checklist which inspectors follow, and then go back to a computer at the end of the day to upload the pictures and the web form “Inspection Web Form”. It’s quite likely that the inspector has performed numerous inspections for the day. At upload time his ability to jog his memory might be faded by the passage of time. It’s quite likely at such time that they have forgotten or missed to capture some key details.

At CarDr.com we realized the need for a live guided mobile Inspection system using a comprehensive checklist to note Vehicle condition but also to connect historical databases and the On Board Diagnostics (OBD) of the Vehicle.

The wealth of information from the OBD is truly breathtaking – it’s like doing an MRI on a car while driving it. It allows for our state-of-the art Machine Learning system to understand the vehicle from the on On-Board Diagnostics.

OBD is a systematic evolution of the modern automobiles. This system monitor’s whether the car’s exhaust exceeds the standard at any time from the running status of the engine . Once the standard is exceeded, a warning will be issued immediately. When the system is faulty , the fault (MIL) light or the check engine (Check Engine) warning light is on, and the powertrain control module (PCM) stores the fault information in the memory. The fault code is  read from the PCM using our Inspector app via our state of the art OBD Scanner.  According to the prompt of the fault code, the maintenance personnel can quickly and accurately determine the nature and location of the fault.

Our Inspector APP scans the OBD and retrieves live 23 OBD parameters. Using these OBD PID’s  we are  able to put our finger on the vehicle’s pulse, read its heartbeat, and see how its vitals change during a test drive. Your used car inspection report will include information such as coolant and engine oil temperature, engine load, and throttle position. With these data points, you can tell how hard your car has to work at getting up to speed, if it needs help staying cool, and what types of repairs might be needed—whether immediately or down the road.

The OBD Parameters scanned include: Engine load, Engine RPM, Vehicle speed, Throttle position, Coolant temperature, Fuel trim, Fuel pressure, Fuel system status, Intake manifold pressure, Intake air temperature, MAF air flow rate, Air status, Oxygen sensor status, Runtime since engine star,t Distance with MIL on, Fuel tank level input, System vapor pressure, Absolute load, value, Hybrid battery pack life, Engine oil temperature, Engine fuel rate, Torque, VIN &  Various DTCs
