Function System functions of the Golf - Ecomatic => Self study programme No.146, Golf - Ecomatic The Ecomatic (clutch electronics) control unit -J327- is equipped with a fault memory. If faults occur in the monitored sensors or components, these are stored in the memory together with an indication of the type of fault. Faults which occur only occasionally are known as sporadic faults and are additionally coded as such. After evaluating the information, the Ecomatic (clutch electronic) control unit -J327- categorizes the different faults and stores them => -fault table-from Page 01-41 . If faults do not reoccur within Electrical faults that affect vehicle performance can be determined with the fault reader V.A.G 1551. The possibilities offered by the self-diagnosis can only be fully utilized with the fault reader V.A.G 1551 in operating mode 1 "Rapid data transfer". Functions which the fault reader V.A.G 1551 can register , List of selectable functions. Ecomatic control unit -J327- fault recognition If a fault is present it will be stored as a statistical fault. If the fault is no longer present after a set period of time or distance travelled, it will be converted to a "sporadic fault". Faults which are stored in the memory as sporadically occurring faults, will be displayed as "sporadic faults" when retrieved by fault reader V.A.G 1551. "SP" appears on the right of the display in such cases. If the printer is switched on, "sporadic faults" are printed out after the fault is addressed. Faults which are stored in the memory as sporadically occurring faults are automatically erased after 1,000 km (625 miles) or 20 hours. If a fault is present which necessitates a fault indication the Ecomatic, gear display and automatic Ecomatic override warning lamps will flash 10 times at a frequency of 1 second, at intervals of 1 minute. |
