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 "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.
