Diagnostic Mode 01 - Read Current System Data
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2017 Audi S5, 2016 Audi S5, 2016 Audi S4, 2015 Audi S5, and 2015 Audi S4. 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".
The current values of the component or system that is being monitored will be displayed on the scan tool screen.
