Diagnostic Mode 01 - Read Current System Data
WARNING: This page is about a different car, the 2009 Audi S8, 2008 Audi S8, and 2007 Audi S8. However, it is still accessible from the selected car via links, so may be relevant.
Diagnostic Mode 01 makes it possible to access current emissions-related measured values and diagnostic data. The original measured values (no replacement values), input and output data and system status information are displayed using Diagnostic Mode 1.
Test requirement
- Coolant temperature at least 80 C.
Procedure
- Connect the scan tool.
- Start the engine and run at idle.
- Select "Diagnostic Mode 1: Obtain data.".
- From the following table, select the desired the "PID" that is to be monitored, e.g. "PID 05-Coolant temperature".
NOTE:
- More than one "PID" may be selected and monitored.
The current values of the component or system that is being monitored will be displayed on the scan tool screen.
