DESCRIPTION - DIAGNOSTIC MULTIPLE CONNECTOR - Fiat GRANDE PUNTO 1.9 Multijet
The vehicle is equipped with numerous electronic control units with an autodiagnostic function. When a diagnostic tester (Examiner or other device) is connected to these control units, self-diagnosis data can be read (parameters, errors) or the available active diagnostic tests can be carried out.All the diagnostic lines flow into the EOBD connector (European On Board Diagnosis) which conforms with Directive 98/69/CE (EURO 3) - ISO standard J1962 - located under the dashboard to the left of the driver above the Body Computer.Via the same connector it is possible to diagnose all the nodes (control units) connected to the low speed B-CAN network and the high-speed C-CAN dynamic control network.
FUNCTIONAL DESCRIPTION - DIAGNOSTIC MULTIPLE CONNECTOR - Fiat GRANDE PUNTO 1.9 Multijet
Central diagnostic socket R10 is supplied directly by the battery at pin 16 of the line protected by fuse F45 of Body Computer M1; pins 4 and 5 are earthed.Pins 6 and 14 are connected to the C-CAN network: electric steering control unit M86, engine control unit M10, lABS/ESP control unit M50 and - in versions with ESP - yaw sensor K74 are monitored and diagnosed via this network.Pin 1 and 9 are connected to the B-CAN network: instrument panel E50, radio P20, Convergence control unit M162, TPMS control unit M47, climate control unit M70, supplementary heater M75, Air Bag control unit M60 and parking sensor control unit M84 are monitored and diagnosed via this network
