Diagnostic Mode 01 - Read Current System Data: 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.
