Diagnostic Options With the PIWIS II Tester

Diagnostic Options With The PIWIS Tester II

The DME functions and diagnostic options largely correspond to those of the DFI control unit EMS SDI 4.1 for the V8 Cayenne engines:
- adaptation to current components/functions (e.g. new sensors/systems)
- extension (e.g. Start Stop system, thermal management).

Fault Memory
- Adaptation to current legal regulations (e.g. USA: Permanent fault memory = Mode A, via Scan Tool)

Fault Deletion Counter
- 40 warm-up phases have to be completed to delete a sporadic fault in order to decrement the deletion counter from 40 to 0

Actual Values
- Mixture adaptations are preserved in the event of an interruption in the power supply
- Extension of actual values (e.g. Start Stop system, thermal management)

Drive Links
- New drive links (e.g. for Start Stop system)

NOTE: For the DFI control unit EMS SDI 6.1 also, a corresponding code comprising letters and numbers is specified in front of every actual value for each actual value filter. This simplifies assignment in the case of different languages. The explanation of individual selected actual values is also new; this function is displayed using the softkey F1 (? / Help) (as with 9X7 DFI vehicles).
