Diagnostic Mode 04 - Erase DTC Memory A8 Lim. Diagnostic Mode 04 makes it lisible to erase the DTC memory and to reset all emissions-related diagnostic data. In that way, all faults in the DTC memory in the ECM and TCM are erased. The adaptation values may also be reset. Emissions-related diagnostic data includes (as applicable): - MIL Status - Number of DTCs - Readiness Bits - Confirmed DTCs - Pending DTCs - DTC that belongs to freeze frame - Freeze frame data - Test results of speci..
Diagnostic Mode 05 - Check Lambda Test Results A8 Lim. Note The diagnostic information for ‚ÄúDiagnostic Mode 5: check lambda test results‚ÄĚ is not supported in this section of the 2007 S8 5.2L Generic Scan Tool service manual and has been moved to ‚ÄúDiagnostic Mode 6: Checking test results of components that are not continuously monitored‚ÄĚ section. Refer to ‚ÄúDiagnostic Mode 6: Checking test results of components that are not continuously monitored‚ÄĚ for the static values of all oxygen sensor..
Diagnostic Mode 06 - Read Test Results for Specific Diagnostic Functions A8 Lim. Diagnostic Mode 06 makes it lisible to retrieve test results for special components and systems which are continuously or not continuously monitored. If the diagnosis of a system is complete, the diagnostic result and the corresponding thresholds are saved and displayed in mode 06. This data remains saved (even with the ignition off) until either new diagnostic results become available or the DTC memory is erase..
Diagnostic Mode 07 - Read Faults Detected During the Current or Last Driving Cycle A8 Lim. Mode 07 makes it lisible to check emissions-related faults which appeared during the current or last driving cycle (pending DTCs).A pending DTC is saved the first time a fault is detected (output via Mode 07). If the fault is detected again by the end of the following driving cycle, a confirmed DTC is entered (output via Mode 03) and the MIL is activated. If this malfunction is not detected again by t..
Diagnostic Mode 08 - Request Control of On-Board System, Test or Component A8 Lim. Diagnostic Mode 08 is used to control the operation of an on-board system, test or component. A Mode 8 service can be used to turn on-board system ON or OFF, or to cycle an on-board system, test or component ON or OFF for a specific period of time. The service can also be used to request system status or to report test results.Diagnostic Mode 08, TID $01Diagnostic Mode 08, TID $01 is used to determine if the e..
Diagnostic Mode 09 - Read Vehicle Information A8 Lim. Diagnostic Mode 09 makes it lisible to access vehicle-specific information from the ECM and the TCM (where applicable). Note Depending on scan tool and protocol used, Diagnostic Mode 09 and the information provided may be referred to by a different name. Test requirement No DTCs stored in the DTC memory. Procedure Connect the scan tool. Switch the ignition on. Select ‚ÄúMode 09: Vehicle information‚ÄĚ. Select the desired ‚ÄúTest-ID‚ÄĚ. Th..
