IGNITION AND INJECTION1717 - 25Diagnostic – GeneralThis document is presenting the diagnostic for the injection computers SIRIUS 32, which havenr.program E1 and Diag.variant 10.In order to perform the diagnostic of this injection system, it is necessary to use the followingelements:- Diagnostic Technical Note- Functional electric diagram of the respective vehicle- CLIP technical tester, 90 ways terminal (ELE 1497).DIAGNOSTIC PERFORMING STEPS- CLIP tester connection to the diagnostic socket for identification of the SIRIUS 32 computertype, of the “E1” program and the diagnostic variant “10”.- Information identification in thedocument “Diagnostic” corresponding to theinjection system.- Reading and observing of the working instructions presented in the diagnostic documentation.- Reading of the failures memorized by the injection computer, by means of the CLIP tester andcauses identification by means of chapter “ Failures interpretation”DO NOT ERASE THE MEMORIZED FAILURES BEFORE READING THEM BYMEANS OF THE CLIP TESTERWrite the memorized failures, after having previously red by means of the CLIP tester, in orderto be taken into consideration and treated, if these are to be themselves erased.1. Treat all existent failures.2. Memorized failures:Perform the operations mentioned in “Recommendations” corresponding to each failure, in orderto confirm the failure.If the failure is becoming present, then it must be treated.3. For vehicle provided with OBD.If the failure is memorized and the OBD indicator is on, read the failure context remarks, thecorresponding state at” OBD indicator lighting requesting”, in order to establish if this is the causefor indicator lighting.In such case, treat the failure as being present.REMARK: the state “ OBD indicator lighting requesting” may be YES or NO and may beconsulted by selecting menu “ FUNCTIONS”, then OBD INDICATOR LIGHTING”.Perform the conformity checking (evidencing of eventually disturbances not yet declared by thesystem self-diagnostic).Validate the reparation performing (failure cause elimination).Take benefit of the information from the failure-locating tree, in case the problem is persisting.vnx.su
