Modularization sense command.
Four, in byte and module type mapping table, the last byte of each frame ID is matched, is identified
To the module type of each frame ID of correspondence, in vehicle and module type mapping table, obtained by the vehicle of current vehicle
The corresponding multiple module types of the vehicle are compared with the module type (which module be assembled with) recognized, are not had
There is the module type (module lost) being identified to.
Which module current vehicle can be assembled with to, those modules are lost and are fed back by the display screen of vehicle diagnostic equipment
To maintenance personal.
The method of the present invention can allow maintenance personal to know which vehicle is assembled with the electronic control module type of automatic identification vehicle
Which module is module be lost, so that auxiliary maintaining personnel diagnose.
Such as: it when maintenance personal's equipment in use checks vehicle, first has to judge whether the vehicle has corresponding module, tradition
Mode be to go directly onboard to look for according to the experience of user completely, for experienced master worker, he may know at a glance
Road is either with or without but for novice users, he may not know the position of this module at which and look like that this just gives
Maintenance increases difficulty, checks at this point, novice users can carry out diagnosis to vehicle by equipment completely, either with or without corresponding mould
Block, user can be shown to by scanning through, and saved the time of maintenance and user is helped to increase service experience.
Wherein, byte and module type mapping table and vehicle and module type mapping table are set to vehicle diagnostics
