Examiner is the Fiat diagnostic tool, if used to its full potential it is very good. The problem is that vehicle electronic systems log things that arent normal as error codes. System ecu's dont log codes for items that are sending an incorrect signal that is still within its min and max limits. The technician interprets the fault codes , the parameter readings obtained and also carries out tests to operate actuators and obtain more information. What you pay for is not just to connect a bit of electronics to your car and read a code, its also to make sense of that code and carry out a full diagnosis.
For example, F1 cars have telemetry and data logging. The techs can see all the data live as it happens, and look back over it inch by inch for a problem at a later date.
Fiat cars have error code storage, which stores a code when something abnormal occurs, depending on the system, it may record certain information regarding certain parameters.
The F1 techs can see exactly what happens at any point in time. The Fiat techs use their skill, product knowledge, and diagnostic abilities to decipher the information they obtain to make a diagnosis. That is why most Techs want to speak to the customer directly and get as much information as possible from them. Technicians ask leading questions to make the customer think about the fault. Sometimes Technicains send customers away with pen and paper to write a diary of what happens and when, to establish a pattern of when a fault occurs.
£75 to connect examiner is alot, £75 to diagnose a fault can be cheap depending on what it needs to diagnose the fault.
