Fantastic Cars And How To Judge Them!

Vehicle inspection methods such as vehicle history, VIN number check, visual inspection won’t let you go far. To determine the true value of a car, you need to look deep and analyze all of the car’s systems to find any hidden problems. Whether you are a car dealer or a buyer or a company selling cars online, CaRPM will always make you feel confident!

So what insights does this CaRPM report provide?

Here is an overview of the report:


CaRPM Inspection Report gives an in-depth view of a car by capturing and analyzing data using an OBD device to identify the problems it has. After a complete assessment of the car’s systems, we rate it based on the fuel economy, pickup, fault(s) and other parameters that summarize the health of the car. The results are reinforced with our algorithms and presented in a very easy to understand report.

Test Drive:

The fuel economy, pickup and torque of the car, based on a test drive, are compared to a brand new car driven in city conditions. It gives an estimate of how much the car’s performance has depreciated since it was bought. The battery section will tell you if the car’s battery is fine and whether or not you need to spend any money on its repairs/replacement.

System Status:

With an ever increasing amount of data flowing in a car, it becomes very difficult to inspect everything in a car in a quick inspection. We have divided these problems into various sections under the System Status section to help identify the malfunctioning parts better. Any fault(s) that appear in the car is categorized into these systems. CaRPM is able to read both, current and potential problems in a car, thereby ensuring that car buyers are never in for unpleasant surprises.The report points out which part/sensor is likely to cause the problem, the causes behind it and helps you understand the total cost of repair for any given car.

Car Maintenance:

The Car Maintenance section gives you an in-depth idea of how well has the car been maintained. It indicates the effects of the way each car has been maintained, and whether it shows any problems due to careless maintenance.

  • Engine misfire and engine knocking are related to incomplete combustion in a gasoline (petrol) engine. As the spark plugs, ignition cables, and ignition coils wear over time, their ability to transfer the needed spark to ignite the air and fuel mixture inside the combustion chambers becomes compromised.We read any anomalies related to the ignition system in the engine.
  • Odometer tampering is a huge problem when buying a used car and the reason is simple, cars with lower mileage sell faster, and are worth more money. We read the mileage stored in the car’s ECU (car’s brain/computer) and have caught several odometer fraud cases.
  • A car that runs at an abnormally high temperature is beyond stressful. It can leave you on the side of the road and later at a repair shop with an expensive repair bill. Don’t worry though, CaRPM keeps an eye on the temperature needle of a car for you.
  • Fuel trim and fuel system relates to sensors that maintain a recommended ratio between the air and fuel mixing in the engine. A warning can be caused by anything as simple as a clogged air/fuel filter or an expensive oxygen (O2) sensor malfunctioning.
  • When the engine of a car is rotating while the car is in a neutral/parking position with “the foot off the gas”, the RPM of the engine then is referred to as Idling RPM. Each car has its own recommended RPM ranges for such cases. Values shooting above recommended ones would cause shaking and unwanted vibrations in the engine.
  • Fuel pressure denotes the pressure with which fuel is carried from the fuel pump to the engine, while boost pressure indicates the maximum boost the car produced during the test drive. The engine might suffer poor performance and have difficulty in starting if the fuel pressure is low.
  • Exhaust emissions are a significant source of pollution and OBD can detect pollution failure giving you a clear picture of the car’s emission status.
  • Color Code:
    CaRPM Inspection Report follows a simple color code — Green denotes perfectly working parts with no problems, Red denotes a warning sign and that the car needs repair work. Yellow signs with a ‘Data not available’ sign appear if certain parameters needed for our algorithms to run are not supported in a car.

How will you get our report?

The CaRPM Inspection Report can be viewed on the web, printed, saved and emailed. The reports are stored on our servers and can be easily retrieved, unlike paper checklists that get lost or thrown in a box.
