How do you choose the best diagnostic scanner

HOW TO SELECT THE BEST DIAGNOSTIC SCANNER

  • Don't be impressed by a list of a number of vehicles ( it may hide an empty box ) or a summary of ECU references.
  • Ask for a list of the operational systems ( for instance MP 5.2 of Peugeot, Bosch EDC 1663 (common rail), Lucas Epix ( diesel control), Siemens SID ( common rail ), etc.

ONLY THE NUMBER OF SYSTEMS DETERMINES THE QUALITY OF POSSIBLE COMMUNICATIONS WITH THE ECU'S

In the technical diagnostic language it is called protocol dialogs and their number confirùs the universality, the power and the possibilities of the scanner.

In technische diagnosetaal spreekt men van protocol dialogen en de hoeveelheid hiervan geeft de veelzijdigheid, de kracht en de mogelijkheden van het toestel aan.

Regarding the yealy software updates; it is not the number of updates that is important, but above all the quantity of added operational systems.

A good scanner has to be able to carry out at least the most essential tasks, but a protocol scanner has to get access to the comfort and related systems as well, such as;

 

Central locking
Interior monitoring
Communication system
Xenon lights
Comfort modules BSI, KBM, BCM
Multiple information screens
Air suspension
Tyre pressure monitoring
Cruise control
Key programming
Electric power steering
Parking brake
Wipers and washers
Rain sensor
Electric seats
Electric contact
Sun roof
Licht module COM 2000 / 2003
Controller area network ( CAN )
Vehicle area network ( VAN )
Etc.

 

 

It's also important to know if the scanner keeps on working when you don't install the updates.
