FI SYSTEM DIAGNOSIS 12-23
SDS CHECK
Using SDS, sample the data at the time of new and periodic vehicle inspections.
After saving the sampled data in the computer, file them by model and by user.
The periodically filed data help improve the accuracy of troubleshooting since they can indicate the condition
of vehicle functions that has changed with time.
For example, when a vehicle is brought in for service but the troubleshooting of a failure is not easy, compar-
ing the current data value to the past filed data value at time of normal condition can allow the specific
engine failure to be determined.
Also, in the case of a customer vehicle which is not periodically brought in for service with no past data value
having been saved, if the data value of a good vehicle condition have been already saved as a master
(STD), comparison between the same models helps facilitate the troubleshooting.
• Set up the SDS tools. ( 12-20)
